Class TrimSuffixEncoder

java.lang.Object

morfologik.stemming.TrimSuffixEncoder

All Implemented Interfaces:

ISequenceEncoder

public class TrimSuffixEncoder
extends java.lang.Object
implements ISequenceEncoder

Encodes dst relative to src by trimming whatever non-equal suffix src has. The output code is (bytes):

 {K}{suffix}
 

where (K - 'A') bytes should be trimmed from the end of src and then the suffix should be appended to the resulting byte sequence.

Examples:

 src: foo
 dst: foobar
 encoded: Abar
 
 src: foo
 dst: bar
 encoded: Dbar

Method Detail

encode

public java.nio.ByteBuffer encode(java.nio.ByteBuffer reuse,
                                  java.nio.ByteBuffer source,
                                  java.nio.ByteBuffer target)

Description copied from interface: ISequenceEncoder

Encodes target relative to source, optionally reusing the provided ByteBuffer.

Specified by:

encode in interface ISequenceEncoder

Parameters:

reuse - Reuses the provided ByteBuffer or allocates a new one if there is not enough remaining space.

source - The source byte sequence.

target - The target byte sequence to encode relative to source

Returns:

Returns the ByteBuffer with encoded target.

decode

public java.nio.ByteBuffer decode(java.nio.ByteBuffer reuse,
                                  java.nio.ByteBuffer source,
                                  java.nio.ByteBuffer encoded)

Description copied from interface: ISequenceEncoder

Decodes encoded relative to source, optionally reusing the provided ByteBuffer.

Specified by:

decode in interface ISequenceEncoder

Parameters:

reuse - Reuses the provided ByteBuffer or allocates a new one if there is not enough remaining space.

source - The source byte sequence.

encoded - The previously encoded byte sequence.

Returns:

Returns the ByteBuffer with decoded target.

toString

public java.lang.String toString()

Overrides:
