Modifier and Type | Method and Description |
---|---|
abstract InputStream |
decorate(IOContext ctxt,
byte[] src,
int offset,
int length)
Method called by
JsonFactory instance when
creating parser on given "raw" byte source. |
DataInput |
decorate(IOContext ctxt,
DataInput input)
Method called by
JsonFactory instance when
creating parser given an DataInput , when this decorator
has been registered. |
abstract InputStream |
decorate(IOContext ctxt,
InputStream in)
Method called by
JsonFactory instance when
creating parser given an InputStream , when this decorator
has been registered. |
abstract Reader |
decorate(IOContext ctxt,
Reader r)
Method called by
JsonFactory instance when
creating parser given an Reader , when this decorator
has been registered. |
public abstract InputStream decorate(IOContext ctxt, InputStream in) throws IOException
JsonFactory
instance when
creating parser given an InputStream
, when this decorator
has been registered.ctxt
- IO context in use (provides access to declared encoding).
NOTE: at this point context may not have all information initialized;
specifically auto-detected encoding is only available once parsing starts,
which may occur only after this method is called.in
- Original input sourceIOException
public abstract InputStream decorate(IOContext ctxt, byte[] src, int offset, int length) throws IOException
JsonFactory
instance when
creating parser on given "raw" byte source.
Method can either construct a InputStream
for reading; or return
null to indicate that no wrapping should occur.ctxt
- IO context in use (provides access to declared encoding)
NOTE: at this point context may not have all information initialized;
specifically auto-detected encoding is only available once parsing starts,
which may occur only after this method is called.src
- Input buffer that contains contents to parseoffset
- Offset of the first available byte in the input bufferlength
- Number of bytes available in the input bufferInputStream
to use as input source; or null to indicate
that contents are to be processed as-is by callerIOException
public DataInput decorate(IOContext ctxt, DataInput input) throws IOException
JsonFactory
instance when
creating parser given an DataInput
, when this decorator
has been registered.
Default implementation simply throws UnsupportedOperationException
