Class SecureHashBuffer

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

        +--ostore.util.SecureHashBuffer

All Implemented Interfaces:

OutputBuffer

Direct Known Subclasses:

SHA1HashBuffer

public abstract class SecureHashBuffer

extends OutputBufferImpl

A MessageDigest-like interface for building SecureHashes.

Users should call add for each object to include in the SecureHash and then call toHash once. Invocations of toHash reset the SecureHashBuffer, so do not attempt to produce intermediate hashes with a single buffer.
