Class AbstractSaslImpl

java.lang.Object

org.jboss.sasl.digest.AbstractSaslImpl

Direct Known Subclasses:

DigestMD5Base

abstract class AbstractSaslImpl
extends java.lang.Object

The base class used by client and server implementations of SASL mechanisms to process properties passed in the props argument and strings with the same format (e.g., used in digest-md5). Also contains utilities for doing int to network-byte-order transformations.
