Method Detail

serialize

public <T extends Serializable> byte[] serialize(T obj)
                 throws IOException

Serializes an object using default serialization. Compresses the byte array.

Specified by:: serialize in interface IElementSerializer

Parameters:: obj - object
Returns:: byte[]
Throws:: IOException - on i/o problem

serializeObject

protected <T extends Serializable> byte[] serializeObject(T obj)
                          throws IOException

Does the basic serialization.

Parameters:: obj - object
Returns:: byte[]
Throws:: IOException - on i/o problem

deSerialize

public <T extends Serializable> T deSerialize(byte[] data)
                                   throws IOException,
                                          ClassNotFoundException

Uses default de-serialization to turn a byte array into an object. Decompresses the value first. All exceptions are converted into IOExceptions.

Specified by:: deSerialize in interface IElementSerializer

Parameters:: data - bytes of data
Returns:: Object
Throws:: IOException - on i/o problem; ClassNotFoundException - if class is not found during deserialization

deserializeObject

protected <T extends Serializable> T deserializeObject(byte[] decompressedByteArray)
                                            throws IOException,
                                                   ClassNotFoundException

Does the standard deserialization.

Parameters:: decompressedByteArray - array of decompressed bytes
Returns:: Object
Throws:: IOException - on i/o error; ClassNotFoundException - if class is not found during deserialization
