Method Detail

encode

public ByteBuffer encode(LinkedNode<T> object)

Description copied from interface: Portability

Encodes an object of type T as a ByteBuffer.

Specified by:

encode in interface Portability<LinkedNode<T>>

Parameters:

object - object to be encoded

Returns:

the encoded object

decode

public LinkedNode<T> decode(ByteBuffer buffer)

Description copied from interface: Portability

Decodes a ByteBuffer to an object of type T.

Specified by:

decode in interface Portability<LinkedNode<T>>

Parameters:

buffer - bytes to decode

Returns:

the decoded object

equals

public boolean equals(Object object,
