Class TrimPrefixAndSuffixEncoder

java.lang.Object

morfologik.stemming.TrimPrefixAndSuffixEncoder

All Implemented Interfaces:

ISequenceEncoder

public class TrimPrefixAndSuffixEncoder
extends java.lang.Object
implements ISequenceEncoder

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

 {P}{K}{suffix}
 

where (P - 'A') bytes should be trimmed from the start of src, (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: abc
 dst: abcd
 encoded: AAd
 
 src: abc
 dst: xyz
 encoded: ADxyz

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
