Interface RawBinaryFactory

All Known Implementing Classes:

SerializableObjectFactory

public interface RawBinaryFactory

Interace of factory for packing/unpacking raw binary objects

Method Summary

int	pack(java.lang.Object obj, byte[] arr, int off) Pack raw binary object to byte array
int	size(java.lang.Object obj) Get size of raw binary object in bytes
boolean	supports(java.lang.Class cls) Check if specified las supported by thisd factory
java.lang.Object	unpack(java.lang.Class cls, byte[] arr, int off, int size) Unpack raw binary object

Method Detail

size

public int size(java.lang.Object obj)

Get size of raw binary object in bytes

Parameters:

obj - raw binary object

Returns:

size of packed raw binary object

pack

public int pack(java.lang.Object obj,
                byte[] arr,
                int off)

Pack raw binary object to byte array

Parameters:

obj - raw binary object

arr - array to store packed image of raw binary object

off - offset in the array where object should be packed

Returns:

bumer of bytes in packed object image. It should be the same as returned by RawBinary.size method.

unpack

public java.lang.Object unpack(java.lang.Class cls,
                               byte[] arr,
                               int off,
                               int size)

Unpack raw binary object

Parameters:

cls - class of raw binary object

arr - array containing packed raw binary object

off - offset of packed binary object in the array

size - size of packed binary object

Returns:

created raw binary object with unpacked content

supports

public boolean supports(java.lang.Class cls)

Check if specified las supported by thisd factory

Parameters:

cls - raw binary object class

Returns:

true if factory is able to pack/unpack instances of these class
