Constructor Detail

BaseSerializingTranscoder

public BaseSerializingTranscoder()

Method Detail

setCompressionThreshold

public void setCompressionThreshold(int to)

Set the compression threshold to the given number of bytes. This transcoder will attempt to compress any data being stored that's larger than this.

Parameters:

to - the number of bytes

setCharset

public void setCharset(java.lang.String to)

Set the character set for string value transcoding (defaults to UTF-8).

serialize

protected byte[] serialize(java.lang.Object o)

Get the bytes representing the given serialized object.

deserialize

protected java.lang.Object deserialize(byte[] in)

Get the object represented by the given serialized bytes.

compress

public static final byte[] compress(byte[] in)

Compress the given array of bytes.

decompress

protected byte[] decompress(byte[] in)

Decompress the given array of bytes.

Returns:

null if the bytes cannot be decompressed

decodeString

protected java.lang.String decodeString(byte[] data)

Decode the string with the current character set.

encodeString

protected byte[] encodeString(java.lang.String in)

Encode a string into the current character set.
