Method Detail

objectToByteBuffer

public byte[] objectToByteBuffer(java.lang.Object obj,
                                 int estimatedSize)

Description copied from interface: Marshaller

Marshalls an object to a byte array. The estimatedSize parameter is a hint that can be passed in to allow for efficient sizing of the byte array before attempting to marshall the object. The more accurate this estimate is, the less likely byte[]s will need to be resized to hold the byte stream generated by marshalling the object.

Specified by:

objectToByteBuffer in interface Marshaller

Parameters:

obj - object to convert to a byte array. Must not be null.

estimatedSize - an estimate of how large the resulting byte array may be

Returns:

a byte array with the marshalled form of the object

objectToByteBuffer

public byte[] objectToByteBuffer(java.lang.Object obj)

Description copied from interface: Marshaller

Marshalls an object to a byte array.

Specified by:

objectToByteBuffer in interface Marshaller

Parameters:

obj - object to convert to a byte array. Must not be null.

Returns:

a byte array

objectFromByteBuffer

public java.lang.Object objectFromByteBuffer(byte[] buf)

Description copied from interface: Marshaller

Unmarshalls an object from a byte array.

Specified by:

objectFromByteBuffer in interface Marshaller

Parameters:

buf - byte array containing the binary representation of an object. Must not be null.

Returns:

an object

objectFromByteBuffer

public java.lang.Object objectFromByteBuffer(byte[] buf,
                                             int offset,
                                             int length)

Description copied from interface: Marshaller

Unmarshalls an object from a specific portion of a byte array.

Specified by:

objectFromByteBuffer in interface Marshaller

Parameters:

buf - byte array containing the binary representation of an object. Must not be null.

offset - point in buffer to start reading

length - number of bytes to consider

Returns:

an object

objectToBuffer

public ByteBuffer objectToBuffer(java.lang.Object o)

Description copied from interface: Marshaller

A method that returns an instance of ByteBuffer, which allows direct access to the byte array with minimal array copying

Specified by:

objectToBuffer in interface Marshaller

Parameters:

o - object to marshall

isMarshallable

public boolean isMarshallable(java.lang.Object o)

Description copied from interface: Marshaller

A method that checks whether the given object is marshallable as per the rules of this marshaller.

Specified by:

isMarshallable in interface Marshaller

Parameters:

o - object to verify whether it's marshallable or not

Returns:

true if the object is marshallable, otherwise false

getBufferSizePredictor

public BufferSizePredictor getBufferSizePredictor(java.lang.Object o)

Description copied from interface: Marshaller

Returns a marshalled payload size predictor for a particular type. Accurate prediction of a type's serialized payload size helps avoid unnecessary copying and speeds up application performance.

Specified by:

getBufferSizePredictor in interface Marshaller

Parameters:

o - Object for which serialized predictor will be returned

Returns:

an instance of BufferSizePredictor

mediaType

public MediaType mediaType()

Specified by:

mediaType in interface Marshaller

Returns:

the MediaType associated with the content produced by the marshaller
