Class ChannelDecisionManagerImpl

java.lang.Object
  org.acegisecurity.securechannel.ChannelDecisionManagerImpl

All Implemented Interfaces:

ChannelDecisionManager, InitializingBean

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.
