The default constructor must be public to allow for instantiation through Java reflection.

Method Details

serialize

public JPPFBuffer serialize(Object o)
                     throws Exception

Serialize an object into an array of bytes.

Specified by:

serialize in interface ObjectSerializer

Parameters:

o - the object to Serialize.

Returns:

a JPPFBuffer instance holding the serialized object.

Throws:

Exception - if the object can't be serialized.

serialize

public JPPFBuffer serialize(Object o,
 boolean noCopy)
                     throws Exception

Serialize an object into an array of bytes.

Specified by:

serialize in interface ObjectSerializer

Parameters:

o - the object to Serialize.

noCopy - avoid copying intermediate buffers.

Returns:

a JPPFBuffer instance holding the serialized object.

Throws:

Exception - if the object can't be serialized.

serialize

public void serialize(Object o,
 OutputStream os)
               throws Exception

Serialize an object into an output stream.

Specified by:

serialize in interface ObjectSerializer

Parameters:

o - the object to Serialize.

os - the output stream to serialize to.

Throws:

Exception - if the object can't be serialized.

serialize

public void serialize(Object o,
 OutputStream os,
 boolean closeStream)
               throws Exception

Serialize an object into an output stream.

Parameters:

o - the object to Serialize.

os - the output stream to serialize to.

closeStream - whether to close the stream before returning.

Throws:

Exception - if the object can't be serialized.

deserialize

public Object deserialize(JPPFBuffer buf)
                   throws Exception

Read an object from an array of bytes.

Specified by:

deserialize in interface ObjectSerializer

Parameters:

buf - buffer holding the array of bytes to deserialize from.

Returns:

the object that was deserialized from the array of bytes.

Throws:

Exception - if the ObjectInputStream used for deserialization raises an error.

deserialize

public Object deserialize(byte[] bytes)
                   throws Exception

Read an object from an array of bytes.

Specified by:

deserialize in interface ObjectSerializer

Parameters:

bytes - buffer holding the array of bytes to deserialize from.

Returns:

the object that was deserialized from the array of bytes.

                   throws Exception

Read an object from an array of bytes.

Specified by:

deserialize in interface ObjectSerializer

Parameters:

bytes - buffer holding the array of bytes to deserialize from.

offset - position at which to start reading the bytes from.

length - the number of bytes to read.

Returns:

the object that was deserialized from the array of bytes.
