Modifier and Type	Method and Description
BufferSizePredictor	getBufferSizePredictor(Object o) Deprecated. Returns a marshalled payload size predictor for a particular type.

Method Detail

getBufferSizePredictor

public BufferSizePredictor getBufferSizePredictor(Object o)

Deprecated.

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

objectToBuffer

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

Deprecated.

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

Parameters:

o - object to marshall

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

Returns:

a ByteBufferImpl

Throws:

Exception

IOException

InterruptedException

objectToBuffer

public ByteBuffer objectToBuffer(Object obj)
                          throws IOException,
                                 InterruptedException

Deprecated.

Description copied from interface: Marshaller

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

Specified by:

objectToBuffer in interface Marshaller

Parameters:

obj - object to marshall

Returns:

a ByteBufferImpl

Throws:

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

InterruptedException - if the marshalling process was interrupted. Clients should take this as a sign that the marshaller is no longer available, maybe due to shutdown, and so no more marshalling should be attempted.

objectToByteBuffer

public byte[] objectToByteBuffer(Object o)
                          throws IOException,
                                 InterruptedException

Deprecated.

Description copied from interface: Marshaller

Marshalls an object to a byte array.

Specified by:

objectToByteBuffer in interface Marshaller

Parameters:

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

Returns:

a byte array

Throws:

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

InterruptedException - if the marshalling process was interrupted. Clients should take this as a sign that the marshaller is no longer available, maybe due to shutdown, and so no more marshalling should be attempted.

objectToByteBuffer

public byte[] objectToByteBuffer(Object obj,
                        int estimatedSize)
                          throws IOException,
                                 InterruptedException

Deprecated.

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

Throws:

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

InterruptedException - if the marshalling was interrupted. Clients should take this as a sign that the marshaller is no longer available, maybe due to shutdown, and so no more unmarshalling should be attempted.

objectFromByteBuffer

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

Deprecated.

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

Throws:

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

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

objectFromInputStream

public Object objectFromInputStream(InputStream inputStream)
                             throws IOException,
                                    ClassNotFoundException

Deprecated.

This method implements StreamingMarshaller.objectFromInputStream(java.io.InputStream), but its implementation has been moved here rather that keeping under a class that implements StreamingMarshaller in order to avoid code duplication.

Throws:

IOException

ClassNotFoundException
