Class InputBufferImpl

java.lang.Object
  |
  +--ostore.util.InputBufferImpl

All Implemented Interfaces:

Cloneable, InputBuffer

Direct Known Subclasses:

ByteArrayInputBuffer, FromBytesInputBuffer, NetworkInputBuffer, RandomAccessFileInputBuffer, StreamInputBuffer

public abstract class InputBufferImpl

extends Object

implements InputBuffer

Implements all of the functionality of InputBuffer except nextByte and nextBytes. A subclass can inherit from this class to implement an InputBuffer interface while only having to define nextByte and nextBytes.

clone

public Object clone()
             throws CloneNotSupportedException

Description copied from interface: InputBuffer

Buffers must support clone such that the read pointer on a cloned buffer is independent of the original. This functionality is used in Tapestry and will be used in SignedQS as well, I think. It relates to the need to deserialize a buffer twice. Whether or not we keep using it is subject to change.

Specified by:

clone in interface InputBuffer

Overrides:

clone in class Object

CloneNotSupportedException
