public class SortingIntEncoder extends IntEncoderFilter
IntEncoderFilterwhich sorts the values to encode in ascending order before encoding them. Encoding therefore happens upon calling
close(). Since this encoder is usually chained with another encoder that relies on sorted values, it does not offer a default constructor.
|Constructor and Description|
Initializes with the given encoder.
|Modifier and Type||Method and Description|
Instructs the encoder to finish the encoding process.
Encodes an integer to the output stream given in
Reinitializes the encoder with the give

reInit. An implementation may do here additional cleanup required to complete the encoding, such as flushing internal buffers, etc.

NOTE: overriding classes should make sure they either call
super.close() or close the output stream themselves.

public IntDecoder createMatchingDecoder()
IntDecoderwhich matches this encoder. Every encoder must return an
nullis not a valid value. If an encoder is just a filter, it should at least return its wrapped encoder's matching decoder.
NOTE: this method should create a new instance of the matching decoder and leave the instance sharing to the caller. Returning the same instance over and over is risky because encoders and decoders are not thread safe.
public void reInit(OutputStream out)
OutputStream. For re-usability it can be changed without the need to reconstruct a new object.
NOTE: after calling
IntEncoder.close(), one must call
this method even if the output stream itself hasn't changed. An example
case is that the output stream wraps a byte, and the output stream itself
is reset, but its instance hasn't changed. Some implementations of
IntEncoder may write some metadata about themselves to the output
stream, and therefore it is imperative that one calls this method before
encoding any data.
