Class ChannelDecisionManagerImpl

java.lang.Object
  extended by org.springframework.security.web.access.channel.ChannelDecisionManagerImpl
All Implemented Interfaces:
InitializingBean, ChannelDecisionManager

public class ChannelDecisionManagerImpl
extends Object
implements ChannelDecisionManager, InitializingBean

Implementation of ChannelDecisionManager.

Iterates through each configured ChannelProcessor. If a ChannelProcessor has any issue with the security of the request, it should cause a redirect, exception or whatever other action is appropriate for the ChannelProcessor implementation.

Once any response is committed (ie a redirect is written to the response object), the ChannelDecisionManagerImpl will not iterate through any further ChannelProcessors.

The attribute "ANY_CHANNEL" if applied to a particular URL, the iteration through the channel processors will be skipped (see SEC-494, SEC-335).
