public class JsonParserSequence extends JsonParserDelegate
JsonParsers to create a single logical sequence of
tokens, as a single JsonParser.
Fairly simple use of JsonParserDelegate: only need
to override nextToken() to handle transition
JsonParser.Feature, JsonParser.NumberType| Modifier and Type | Field and Description |
|---|---|
protected int |
_nextParser
Index of the next parser in
_parsers. |
protected JsonParser[] |
_parsers
Parsers other than the first one (which is initially assigned
as delegate)

close()
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. |
int |
containedParsersCount()
Method that is most useful for debugging or testing;
returns actual number of underlying parsers sequence
was constructed with (nor just ones remaining active)
|
static JsonParserSequence |
createFlattened(JsonParser first,
JsonParser second)
Method that will construct a parser (possibly a sequence) that
contains all given sub-parsers.
|
JsonToken |
nextToken()
Main iteration method, which will advance stream enough
to determine type of the next token, if any.
|
protected boolean |
switchToNext()
Method that will switch active parser from the current one
to next parser in sequence, if there is another parser left,
making this the new delegate.

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.close in interface Closeableclose in interface AutoCloseableclose in class JsonParserDelegateIOExceptionpublic JsonToken nextToken() throws IOException, JsonParseException
