Modifier and Type	Method and Description
byte[]	decode(ByteBuffer buffer) Decodes a ByteBuffer to an object of type T.
ByteBuffer	encode(byte[] object) Encodes an object of type T as a ByteBuffer.
boolean	equals(Object value, ByteBuffer readBuffer) Byte arrays do not have a content-based equals method so this throws UnsupportedOperationException.

Method Detail

encode

public ByteBuffer encode(byte[] object)

Description copied from interface: Portability

Encodes an object of type T as a ByteBuffer.

Specified by:

encode in interface Portability<byte[]>

Parameters:

object - object to be encoded

Returns:

the encoded object

decode

public byte[] decode(ByteBuffer buffer)

Description copied from interface: Portability

Decodes a ByteBuffer to an object of type T.

Specified by:

decode in interface Portability<byte[]>

Parameters:

buffer - bytes to decode

Returns:

the decoded object

equals

public boolean equals(Object value,
                      ByteBuffer readBuffer)
               throws UnsupportedOperationException

Byte arrays do not have a content-based equals method so this throws UnsupportedOperationException.

The lack of any implementation only prevents this portability being used as a key portability. Using byte arrays as keys in map would be extremely questionable in any case. If necessary this portability could be sub-classed to do deep array comparison.

Specified by:

equals in interface Portability<byte[]>

Parameters:

value - object to compare to

readBuffer - buffer containing encoded object

Returns:

true if the two parameters are "equal"

Throws:

UnsupportedOperationException
