UTF8StreamJsonParser

public UTF8StreamJsonParser(IOContext ctxt,
                            int features,
                            InputStream in,

                            boolean bufferRecyclable)
Method Detail

getCodec

public ObjectCodec getCodec()
Description copied from class: JsonParser
Accessor for ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:
getCodec in class JsonParser

setCodec

public void setCodec(ObjectCodec c)
Description copied from class: JsonParser
Setter that allows defining ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:
setCodec in class JsonParser

version

public Version version()
Description copied from class: JsonParser
Accessor for getting version of the core package, given a parser instance. Left for sub-classes to implement.

Specified by:
version in interface Versioned
Overrides:
version in class ParserMinimalBase

releaseBuffered

public int releaseBuffered(OutputStream out)
                    throws IOException
Description copied from class: JsonParser
Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given stream if possible; if underlying input is byte-based it can released, if not (char-based) it can not.

Overrides:
releaseBuffered in class JsonParser
Returns:
-1 if the underlying content source is not byte based (that is, input can not be sent to OutputStream; otherwise number of bytes released (0 if there was nothing to release)
Throws:
IOException - if write to stream threw exception

getInputSource

public Object getInputSource()
Description copied from class: JsonParser
Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Overrides:
getInputSource in class JsonParser

loadMore

protected boolean loadMore()
                    throws IOException
Specified by:
loadMore in class ParserBase
Throws:
IOException

_loadToHaveAtLeast

protected boolean _loadToHaveAtLeast(int minAvailable)
                              throws IOException
Helper method that will try to load at least specified number bytes in input buffer, possible moving existing data around if necessary

Throws:
IOException

_closeInput

protected void _closeInput()
                    throws IOException
Specified by:
_closeInput in class ParserBase
Throws:
IOException

_releaseBuffers

protected void _releaseBuffers()
                        throws IOException
Method called to release internal buffers owned by the base reader. This may be called along with _closeInput() (for example, when explicitly closing this reader instance), or separately (if need be).

Overrides:
_releaseBuffers in class ParserBase
Throws:
IOException

getText

public String getText()
               throws IOException,
                      JsonParseException
Description copied from class: JsonParser
Method for accessing textual representation of the current token; if no current token (before first call to JsonParser.nextToken(), or after encountering end-of-input), returns null. Method can be called for any token type.

Specified by:
getText in class ParserMinimalBase
Throws:
IOException
JsonParseException

getValueAsString

public String getValueAsString()
                        throws IOException,
                               JsonParseException
Description copied from class: JsonParser
Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), default value of null will be returned; no exceptions are thrown.

Overrides:
getValueAsString in class JsonParser
Throws:
IOException
JsonParseException

getValueAsString

public String getValueAsString(String defValue)
                        throws IOException,
                               JsonParseException
Description copied from class: JsonParser
Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), specified default value will be returned; no exceptions are thrown.

Overrides:
getValueAsString in class ParserMinimalBase
Throws:
IOException
JsonParseException

_getText2

protected String _getText2(JsonToken t)

getTextCharacters

public char[] getTextCharacters()
                         throws IOException,
                                JsonParseException
Description copied from class: JsonParser
Method similar to JsonParser.getText(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over JsonParser.getText()) is to avoid construction of a String object (which will make a copy of contents).

Specified by:
getTextCharacters in class ParserMinimalBase
Throws:
IOException
JsonParseException

getTextLength

public int getTextLength()
                  throws IOException,
                         JsonParseException
Description copied from class: JsonParser
Accessor used with JsonParser.getTextCharacters(), to know length of String stored in returned buffer.

Specified by:
getTextLength in class ParserMinimalBase
Returns:
Number of characters within buffer returned by JsonParser.getTextCharacters() that are part of textual content of the current token.
Throws:
IOException
JsonParseException

getTextOffset

public int getTextOffset()
                  throws IOException,
                         JsonParseException
Description copied from class: JsonParser
Accessor used with JsonParser.getTextCharacters(), to know offset of the first text content character within buffer.

Specified by:
getTextOffset in class ParserMinimalBase
Returns:
Offset of the first character within buffer returned by JsonParser.getTextCharacters() that is part of textual content of the current token.
Throws:
IOException
JsonParseException

getEmbeddedObject

public Object getEmbeddedObject()
                         throws IOException,
                                JsonParseException
Description copied from class: JsonParser
Accessor that can be called if (and only if) the current token is JsonToken.VALUE_EMBEDDED_OBJECT. For other token types, null is returned.

Note: only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees).

Specified by:
getEmbeddedObject in class JsonParser
Throws:
IOException
JsonParseException

getBinaryValue

public byte[] getBinaryValue(Base64Variant b64variant)
                      throws IOException,
                             JsonParseException
Description copied from class: JsonParser
Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JsonParser.getText() and decoding result (except for decoding part), but should be significantly more performant.

Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

Specified by:
getBinaryValue in class ParserMinimalBase
Parameters:
b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).
Returns:
Decoded binary data
Throws:
IOException
JsonParseException

readBinaryValue

public int readBinaryValue(Base64Variant b64variant,
                           OutputStream out)
                    throws IOException,
                           JsonParseException
Description copied from class: JsonParser
Similar to JsonParser.readBinaryValue(OutputStream) but allows explicitly specifying base64 variant to use.

Overrides:
readBinaryValue in class JsonParser
Parameters:
b64variant - base64 variant to use
out - Output stream to use for passing decoded binary data
Returns:
Number of bytes that were decoded and written via OutputStream
Throws:
IOException
JsonParseException

_readBinary

protected int _readBinary(Base64Variant b64variant,
                          OutputStream out,
                          byte[] buffer)
                   throws IOException,
                          JsonParseException
Throws:
IOException
JsonParseException

public JsonToken nextToken()
                    throws IOException,
                           JsonParseException
Description copied from class: JsonParser
Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.

Specified by:
nextToken in class ParserMinimalBase
Returns:
Next token from the stream, if any found, or null to indicate end-of-input
Throws:
IOException
JsonParseException

close

public void close()
           throws IOException
Description copied from class: JsonParser
Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled. Whether parser owns the input source depends on factory method that was used to construct instance (so check JsonFactory for details, but the general idea is that if caller passes in closable resource (such as InputStream or Reader) parser does NOT own the source; but if it passes a reference (such as File or URL and creates stream or reader it does own them.

Specified by:
close in interface Closeable
Overrides:
close in class ParserBase
Throws:
IOException

nextFieldName

public boolean nextFieldName(SerializableString str)
                      throws IOException,
                             JsonParseException
Description copied from class: JsonParser
Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.FIELD_NAME with specified name and returns result of that comparison. It is functionally equivalent to:
  return (nextToken() == JsonToken.FIELD_NAME) && str.getValue().equals(getCurrentName());
but may be faster for parser to verify, and can therefore be used if caller expects to get such a property name from input next.

Overrides:
nextFieldName in class JsonParser
Parameters:
str - Property name to compare next token to (if next token is JsonToken.FIELD_NAME)
Throws:
IOException
JsonParseException

                            JsonParseException
Description copied from class: JsonParser
Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_STRING returns contained String value; otherwise returns null. It is functionally equivalent to:
  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;
but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:
nextTextValue in class JsonParser
Throws:

Description copied from class: JsonParser
Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 32-bit int value; otherwise returns specified default value It is functionally equivalent to:
  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getIntValue() : defaultValue;
but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:
nextIntValue in class JsonParser
Throws:
IOException
JsonParseException

nextLongValue

public long nextLongValue(long defaultValue)
                   throws IOException,
                          JsonParseException
Description copied from class: JsonParser
Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 64-bit long value; otherwise returns specified default value It is functionally equivalent to:
  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getLongValue() : defaultValue;
but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Description copied from class: JsonParser
Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE returns matching Boolean value; otherwise return null. It is functionally equivalent to:
  JsonToken t = nextToken();
  if (t == JsonToken.VALUE_TRUE) return Boolean.TRUE;
  if (t == JsonToken.VALUE_FALSE) return Boolean.FALSE;
  return null;
but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Throws:

JsonParseException

parseNumberText

protected JsonToken parseNumberText(int c)
                             throws IOException,
                                    JsonParseException
Initial parsing method for number values. It needs to be able to parse enough input to be able to determine whether the value is to be considered a simple integer value, or a more generic decimal value: latter of which needs to be expressed as a floating point number. The basic rule is that if the number has no fractional or exponential part, it is an integer; otherwise a floating point number.

Because much of input has to be processed in any case, no partial parsing is done: all input text will be stored for further processing. However, actual numeric value conversion will be deferred, since it is usually the most complicated and costliest part of processing.

Throws:
IOException
JsonParseException

slowParseFieldName

protected Name slowParseFieldName()
                           throws IOException,
                                  JsonParseException
Method called when not even first 8 bytes are guaranteed to come consequtively. Happens rarely, so this is offlined; plus we'll also do full checks for escaping etc.

Throws:
IOException
JsonParseException

parseEscapedFieldName

protected Name parseEscapedFieldName(int[] quads,
                                     int qlen,

                                     int ch,
                                     int currQuadBytes)
                              throws IOException,
                                     JsonParseException
Slower parsing method which is generally branched to when an escape sequence is detected (or alternatively for long names, or ones crossing input buffer boundary). In any case, needs to be able to handle more exceptional cases, gets slower, and hance is offlined to a separate method.

Throws:
IOException
JsonParseException

_handleUnusualFieldName

protected Name _handleUnusualFieldName(int ch)
                                throws IOException,
                                       JsonParseException
Method called when we see non-white space character other than double quote, when expecting a field name. In standard mode will just throw an expection; but in non-standard modes may be able to parse name.

Throws:
IOException
JsonParseException

                           JsonParseException
Method called to skim through rest of unparsed String value, if it is not needed. This can be done bit faster if contents need not be stored for future access.

Throws:
IOException
JsonParseException

Method for handling cases where first non-space character of an expected value token is not legal for standard JSON content.

Throws:
IOException
