abstract java.io.InputStream |
decorate(IOContext ctxt,
byte[] src,
int offset,
int length)
Method called by
JsonFactory instance when
creating parser on given "raw" byte source. |
java.io.DataInput |
decorate(IOContext ctxt,
java.io.DataInput input)
Method called by
JsonFactory instance when
creating parser given an DataInput, when this decorator
has been registered. |
abstract java.io.InputStream |
decorate(IOContext ctxt,
java.io.InputStream in)
Method called by
JsonFactory instance when
creating parser given an InputStream, when this decorator
has been registered. |
abstract java.io.Reader |
decorate(IOContext ctxt,
java.io.Reader r)
Method called by
JsonFactory instance when
creating parser given an Reader, when this decorator
has been registered. |
public abstract java.io.InputStream decorate(IOContext ctxt, java.io.InputStream in) throws java.io.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 sourcejava.io.IOExceptionpublic abstract java.io.InputStream decorate(IOContext ctxt, byte[] src, int offset, int length) throws java.io.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 callerjava.io.IOExceptionpublic java.io.DataInput decorate(IOContext ctxt, java.io.DataInput input) throws java.io.IOException
JsonFactory instance when
creating parser given an DataInput, when this decorator
has been registered.
Default implementation simply throws UnsupportedOperationException
