Interface ChannelProcessor

All Known Implementing Classes:

InsecureChannelProcessor, SecureChannelProcessor

public interface ChannelProcessor

Decides whether a web channel meets a specific security condition.

ChannelProcessor implementations are iterated by the ChannelDecisionManagerImpl.

If an implementation has an issue with the channel security, they should take action themselves. The callers of the implementation do not take any action.
