Method Detail

register

public void register(org.infinispan.protostream.SerializationContextInitializer initializer)

getSerializationContext

public org.infinispan.protostream.SerializationContext getSerializationContext()

Returns:

the SerializationContext instance to use

objectFromByteBuffer

public Object objectFromByteBuffer(byte[] buf,
                                   int offset,
                                   int length)
                            throws IOException,
                                   ClassNotFoundException

Description copied from interface: Marshaller

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

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

Throws:

IOException - if unmarshalling cannot complete due to some I/O error

ClassNotFoundException - if the class of the object trying to unmarshall is unknown

isMarshallable

public boolean isMarshallable(Object o)

Description copied from interface: Marshaller

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

Parameters:

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

Returns:

true if the object is marshallable, otherwise false

objectToBuffer

protected ByteBuffer objectToBuffer(Object o,
                                    int estimatedSize)
                             throws IOException

Description copied from class: AbstractMarshaller

This is a convenience method for converting an object into a ByteBuffer which takes an estimated size as parameter. A ByteBuffer allows direct access to the byte array with minimal array copying

Specified by:

objectToBuffer in class AbstractMarshaller

Parameters:

o - object to marshall

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

Throws:

IOException

mediaType

public MediaType mediaType()

Returns:

the MediaType associated with the content produced by the marshaller
