public BinaryHandler(boolean pisCompressed)

Creates a Binary Handler.

Parameters:

public BinaryHandler()

Method Detail

serialize

public void serialize(Object data,
             Object metaData,
             CompressibleByteArrayOutputStream op,
             ServerInfo serverInfo)
               throws IOException

The data to serialize must be a byte array.

Specified by:

serialize in interface DataHandler

Parameters:

data - Data to serialize

metaData - Additional Info to serialize if required by the handler like the Object Class for example. Pass null if the Data Handler does not require addtional info.

op - An output stream which can automatically compress the data in a session if it crosses a configured. Compression Threshold

serverInfo - Redis ServerInfo containing the Redis Server details

Throws:

IOException - If there is an error during serialization

deserialize

public Object deserialize(Object metaData,
                 byte[] b,
                 int offset,
                 int len,
                 ServerInfo serverInfo)
                   throws IOException

Description copied from interface: DataHandler

de-serialize value

Specified by:

deserialize in interface DataHandler

Parameters:

metaData - Additional Info to de-serialize if required by the handler

b - Byte Array containing the data from the Redis Server

offset - Starting offset of the data

len - Length of the data in bytes

serverInfo - Redis ServerInfo containing the Redis Server details

Returns:

De-serialized Data

Throws:

IOException - If there is an error during de-serialization
