writePayload

public void writePayload(java.lang.Integer object,
                java.io.DataOutput dataOut)
                  throws java.io.IOException

Description copied from interface: Marshaller

Write the payload of the object to the DataOutput stream.

Specified by:

writePayload in interface Marshaller<java.lang.Integer>

Throws:

java.io.IOException

readPayload

public java.lang.Integer readPayload(java.io.DataInput dataIn)
                              throws java.io.IOException

Description copied from interface: Marshaller

Read the payload of the object from the DataInput stream.

Specified by:

readPayload in interface Marshaller<java.lang.Integer>

Returns:

unmarshalled object

Throws:

java.io.IOException

getFixedSize

public int getFixedSize()

Specified by:

getFixedSize in interface Marshaller<java.lang.Integer>

Returns:

-1 if the object do not always marshall to a fixed size, otherwise return that fixed size.

deepCopy

public java.lang.Integer deepCopy(java.lang.Integer source)

Specified by:

deepCopy in interface Marshaller<java.lang.Integer>

Returns:

the source object since integers are immutable.

isDeepCopySupported

public boolean isDeepCopySupported()

Specified by:

isDeepCopySupported in interface Marshaller<java.lang.Integer>

Returns:

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