Class StemmerPatchTrieBinaryIO

java.lang.Object

org.egothor.stemmer.StemmerPatchTrieBinaryIO

public final class StemmerPatchTrieBinaryIO
extends Object

Binary persistence helper for patch-command stemmer tries.

This class persists FrequencyTrie instances whose values are compact patch commands represented as String. The serialized trie payload is the native binary format of FrequencyTrie, wrapped in GZip compression.

The helper centralizes the codec and compression details so that higher-level loader APIs can remain focused on source selection rather than stream mechanics.

Method Details

read

public static FrequencyTrie<String> read(Path path)
                                  throws IOException

Reads a GZip-compressed binary patch-command trie from a filesystem path.

Parameters:

path - source file

Returns:

deserialized trie

Throws:

NullPointerException - if path is null

IOException - if reading or decompression fails

read

public static FrequencyTrie<String> read(String fileName)
                                  throws IOException

Reads a GZip-compressed binary patch-command trie from a filesystem path string.

Parameters:

fileName - source file name or path string

Returns:

deserialized trie

Throws:

NullPointerException - if fileName is null

IOException - if reading or decompression fails

read

public static FrequencyTrie<String> read(InputStream inputStream)
                                  throws IOException

Reads a GZip-compressed binary patch-command trie from an input stream.

The supplied stream is consumed but not interpreted as plain trie bytes; it is first decompressed using GZIPInputStream.

Parameters:

inputStream - source stream

Returns:

deserialized trie

Throws:

NullPointerException - if inputStream is null

IOException - if reading or decompression fails

write

public static void write(FrequencyTrie<String> trie,
 Path path)
                  throws IOException

Writes a GZip-compressed binary patch-command trie to a filesystem path.

Parameters:

trie - trie to persist

path - target file

Throws:

NullPointerException - if any argument is null

IOException - if writing fails

write

public static void write(FrequencyTrie<String> trie,
 String fileName)
                  throws IOException

Writes a GZip-compressed binary patch-command trie to a filesystem path string.

Parameters:

trie - trie to persist

fileName - target file name or path string

Throws:

NullPointerException - if any argument is null

IOException - if writing fails

write

public static void write(FrequencyTrie<String> trie,
 OutputStream outputStream)
                  throws IOException

Writes a GZip-compressed binary patch-command trie to an output stream.

Parameters:

trie - trie to persist

outputStream - target stream

Throws:

NullPointerException - if any argument is null

IOException - if writing fails
