Method Detail

getFixedSize

public int getFixedSize()

Specified by:

getFixedSize in interface Codec<T>

Returns:

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

isDeepCopySupported

public boolean isDeepCopySupported()

Specified by:

isDeepCopySupported in interface Codec<T>

Returns:

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

deepCopy

public T deepCopy(T source)

Specified by:

deepCopy in interface Codec<T>

Returns:

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

isEstimatedSizeSupported

public boolean isEstimatedSizeSupported()

Specified by:

isEstimatedSizeSupported in interface Codec<T>

Returns:

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

estimatedSize

public int estimatedSize(T object)

Specified by:

estimatedSize in interface Codec<T>

Returns:

the estimated marshaled size of the object.
