Package morfologik.stemming
Class TrimSuffixEncoder
java.lang.Object
morfologik.stemming.TrimSuffixEncoder
- All Implemented Interfaces:
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

encode
Description copied from interface:ISequenceEncoder
- Specified by:
encode
in interfaceISequenceEncoder
- Parameters:
reuse
- Reuses the providedByteBuffer
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 tosource
- Returns:
- Returns the
ByteBuffer
with encodedtarget
.
-
prefixBytes
public int prefixBytes()Description copied from interface:ISequenceEncoder
The number of encoded form's prefix bytes that should be ignored (needed for separator lookup). An ugly workaround for GH-85, should be fixed by prior knowledge of whether the dictionary contains tags; then we can scan for separator right-to-left.- Specified by:
prefixBytes
in interfaceISequenceEncoder

decode
Description copied from interface:ISequenceEncoder

decode
in interfaceISequenceEncoder
- Parameters:
reuse
- Reuses the providedByteBuffer
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
