Interface OutputProcessor

All Known Implementing Classes:

AbstractBufferingOutputProcessor, AbstractEncryptEndingOutputProcessor, AbstractEncryptOutputProcessor, AbstractEncryptOutputProcessor.AbstractInternalEncryptionOutputProcessor, AbstractOutputProcessor, AbstractSignatureEndingOutputProcessor, AbstractSignatureEndingOutputProcessor.SignedInfoProcessor, AbstractSignatureOutputProcessor, AbstractSignatureOutputProcessor.InternalSignatureOutputProcessor, FinalOutputProcessor, XMLEncryptOutputProcessor, XMLSignatureEndingOutputProcessor, XMLSignatureOutputProcessor

public interface OutputProcessor

This is the Interface which every OutputProcessor must implement. The order of processors is defined by:

1. XMLSecurityConstants.Phase (required)
2. Action order (optional): allows grouping processors per action without them accidentally being reordered incorrectly by processors of unrelated other action. It helps grouping processors where before/after processor classes doesn't cut it: signature-after-encryption is a valid use case, but also encryption-after-signature. There is no absolute ordering of signature processors versus encryption processors. That is where the action order comes in: whichever action comes first, it groups those processors together such they can't accidentally get mingled in between processors of unrelated actions. It's optional, if you set the action order to -1 it will be ignored. The action order thus only defines the order between two processors if both these processors have an action order != -1.
3. Before/after processors based on processor classes (optional): this allows ordering of processors typically belonging to a single action.
