  com.fasterxml.jackson.core.format.InputAccessor.Std

All Implemented Interfaces:

InputAccessor

Enclosing interface:

InputAccessor

public static class InputAccessor.Std
extends Object
implements InputAccessor

Basic implementation that reads data from given InputStream and buffers it as necessary.

Nested Class Summary

Nested classes/interfaces inherited from interface com.fasterxml.jackson.core.format.InputAccessor

InputAccessor.Std

Field Summary

protected byte[]	_buffer
protected int	_bufferedAmount Number of bytes in _buffer that are valid buffered content.
protected InputStream	_in
protected int	_ptr Pointer to next available buffered byte in _buffer.

Constructor Summary

InputAccessor.Std(byte[] inputDocument)
Constructor used when the full input (or at least enough leading bytes of full input) is available.

InputAccessor.Std(InputStream in, byte[] buffer)
Constructor used when content to check is available via input stream and must be read.

Method Summary

DataFormatMatcher	createMatcher(JsonFactory match, MatchStrength matchStrength)
boolean	hasMoreBytes() Method to call to check if more input is available.
byte	nextByte() Returns next byte available, if any; if no more bytes are available, will throw EOFException.
void	reset() Method that can be called to reset accessor to read from beginning of input.

Constructor Detail

InputAccessor.Std

public InputAccessor.Std(InputStream in,
                         byte[] buffer)

Constructor used when content to check is available via input stream and must be read.

InputAccessor.Std

public InputAccessor.Std(byte[] inputDocument)

Constructor used when the full input (or at least enough leading bytes of full input) is available.

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

Throws:

IOException

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

Throws:

IOException

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)
