Method Detail

encode

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

Write the payload of the object to the DataOutput stream.

Parameters:

object -

dataOut -

Throws:

java.io.IOException

decode

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

Read the payload of the object from the DataInput stream.

Parameters:

dataIn -

Returns:

unmarshalled object

Throws:

java.io.IOException

getFixedSize

int getFixedSize()

Returns:

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

isEstimatedSizeSupported

boolean isEstimatedSizeSupported()

Returns:

true if the estimatedSize(Object) operation is supported.

estimatedSize

int estimatedSize(T object)

Parameters:

object -

Returns:

the estimated marshaled size of the object.

isDeepCopySupported

boolean isDeepCopySupported()

Returns:

true if the deepCopy(Object) operations is supported.

deepCopy

T deepCopy(T source)

Returns:

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