Method Detail

encode

public void encode(T value,
                   java.io.DataOutput dataOut)
            throws java.io.IOException

Description copied from interface: Codec

Write the payload of the object to the DataOutput stream.

Throws:

java.io.IOException

decode

public T decode(java.io.DataInput dataIn)
         throws java.io.IOException

Description copied from interface: Codec

Read the payload of the object from the DataInput stream.

Returns:

unmarshalled object

Throws:

java.io.IOException

createBuffer

protected abstract T createBuffer(byte[] data)

deepCopy

public T deepCopy(T source)

Specified by:

deepCopy in interface Codec<T extends Buffer>

Overrides:

deepCopy in class VariableCodec<T extends Buffer>

Returns:

a deep copy of the source object. If the source is immutable the same source should be returned.

isDeepCopySupported

public boolean isDeepCopySupported()

Specified by:

isDeepCopySupported in interface Codec<T extends Buffer>

Overrides:

isDeepCopySupported in class VariableCodec<T extends Buffer>

Returns:

true if the Codec.deepCopy(Object) operations is supported.

isEstimatedSizeSupported

public boolean isEstimatedSizeSupported()

Specified by:

isEstimatedSizeSupported in interface Codec<T extends Buffer>

Overrides:

isEstimatedSizeSupported in class VariableCodec<T extends Buffer>

Returns:

true if the Codec.estimatedSize(Object) operation is supported.

estimatedSize

public int estimatedSize(T object)

Specified by:

estimatedSize in interface Codec<T extends Buffer>

Overrides:

estimatedSize in class VariableCodec<T extends Buffer>

Returns:

the estimated marshaled size of the object.
