size

public int size()

Description copied from class: Payload

Return the estimate of in-memory size of this payload.

Specified by:

size in class Payload

Returns:

An estimate of the in-memory size of this payload.

serializedSize

public int serializedSize()

Description copied from class: Payload

Return the estimate of serialized size of this payload when passed through serialization. The estimate needs to be reasonably accurate and should err on the side of caution and report a slightly-higher size in face of uncertainty.

Specified by:

serializedSize in class Payload

Returns:

An estimate of serialized size.

writeReplace

protected Object writeReplace()

Description copied from class: Payload

Return the serialization proxy for this object.

Specified by:

writeReplace in class Payload

Returns:

Serialization proxy
