Method Details

encode

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

Description copied from interface: Codec

Write the payload of the object to the DataOutput stream.

Parameters:

value -

dataOut -

Throws:

IOException

decode

public T decode(DataInput dataIn)
         throws IOException

Description copied from interface: Codec

Read the payload of the object from the DataInput stream.

Parameters:

dataIn -

Returns:

unmarshalled object

Throws:

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>

Parameters:

object -

Returns:

the estimated marshaled size of the object.
