Method Detail

hasMoreBytes

public boolean hasMoreBytes()
                     throws IOException

Description copied from interface: InputAccessor

Method to call to check if more input is available. Since this may result in more content to be read (at least one more byte), a IOException may get thrown.

Specified by:

hasMoreBytes in interface InputAccessor

Returns:

Whether there is at least one more input byte accessible

Throws:

IOException - If check for more content failed due to issue with underlying input abstraction

nextByte

public byte nextByte()
              throws IOException

Description copied from interface: InputAccessor

Returns next byte available, if any; if no more bytes are available, will throw EOFException.

Specified by:

nextByte in interface InputAccessor

Returns:

Next content byte, if available

Throws:

IOException - If called and there is no more content available

reset

public void reset()

Description copied from interface: InputAccessor

Method that can be called to reset accessor to read from beginning of input.

Specified by:

reset in interface InputAccessor

createMatcher

public DataFormatMatcher createMatcher(JsonFactory match,
                                       MatchStrength matchStrength)
