SerializableObjectFactory

public SerializableObjectFactory()

Method Detail

size

public int size(java.lang.Object obj)

Description copied from interface: RawBinaryFactory

Get size of raw binary object in bytes

Specified by:

size in interface RawBinaryFactory

Parameters:

obj - raw binary object

Returns:

size of packed raw binary object

pack

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

Description copied from interface: RawBinaryFactory

Pack raw binary object to byte array

Specified by:

pack in interface RawBinaryFactory

Parameters:

obj - raw binary object

arr - array to store packed image of raw binary object

offs - 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)

Description copied from interface: RawBinaryFactory

Unpack raw binary object

Specified by:

unpack in interface RawBinaryFactory

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)

Description copied from interface: RawBinaryFactory

Check if specified las supported by thisd factory

Specified by:

supports in interface RawBinaryFactory

Parameters:

cls - raw binary object class

Returns:

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