Method Detail

reset

public void reset()

Description copied from interface: ProcessorChain

resets the chain so that the next event will go again to the first processor in the chain.

Specified by:

reset in interface ProcessorChain

getSecurityContext

public OutboundSecurityContext getSecurityContext()

Description copied from interface: OutputProcessorChain

The actual processed document's security context

Specified by:

getSecurityContext in interface OutputProcessorChain

Returns:

The InboundSecurityContext

getDocumentContext

public DocumentContext getDocumentContext()

Description copied from interface: OutputProcessorChain

The actual processed document's document context

Specified by:

getDocumentContext in interface OutputProcessorChain

Returns:

The DocumentContext

addProcessor

public void addProcessor(OutputProcessor newOutputProcessor)

Description copied from interface: OutputProcessorChain

Adds an OutputProcessor to the chain. The place where it will be applied can be controlled through the Phase, getBeforeProcessors and getAfterProcessors. @see Interface OutputProcessor

Specified by:

addProcessor in interface OutputProcessorChain

Parameters:

newOutputProcessor - The OutputProcessor which should be placed in the chain

removeProcessor

public void removeProcessor(OutputProcessor outputProcessor)

Description copied from interface: OutputProcessorChain

Removes the specified OutputProcessor from this chain.

Specified by:

removeProcessor in interface OutputProcessorChain

Parameters:

outputProcessor - to remove

getProcessors

public List<OutputProcessor> getProcessors()

Description copied from interface: OutputProcessorChain

Returns a list with the active processors.

Specified by:

getProcessors in interface OutputProcessorChain

Returns:

List

processEvent

public void processEvent(XMLSecEvent xmlSecEvent)
                  throws XMLStreamException,
                         XMLSecurityException

Description copied from interface: OutputProcessorChain

Forwards the XMLEvent to the next processor in the chain.

Specified by:

processEvent in interface OutputProcessorChain

Parameters:

xmlSecEvent - The XMLEvent which should be forwarded to the next processor

Throws:

XMLStreamException - thrown when a streaming error occurs

XMLSecurityException - thrown when a Security failure occurs

doFinal

public void doFinal()
             throws XMLStreamException,
                    XMLSecurityException

Description copied from interface: ProcessorChain

Will finally be called when the whole document is processed Important note: Every processor in the chain has to call doFinal() in its own doFinal() method. InputProcessors should call it before doing other stuff to keep the processing order. Remember the input-chain is in principle processed in the reverse order since we "leech" the events through the chain. So that means that we should do the same for the doFinal method, otherwise we may run into troubles.

Specified by:

doFinal in interface ProcessorChain

Throws:

XMLStreamException - thrown when a streaming error occurs

XMLSecurityException - thrown when a Security failure occurs

createSubChain

public OutputProcessorChain createSubChain(OutputProcessor outputProcessor)
                                    throws XMLStreamException,
                                           XMLSecurityException

Description copied from interface: OutputProcessorChain

Create a new SubChain. The XMLEvents will be only be processed from the given OutputProcessor to the end. All earlier OutputProcessors don't get these events. In other words the chain will be splitted in two parts.

Specified by:

createSubChain in interface OutputProcessorChain

Parameters:

outputProcessor - The OutputProcessor position the XMLEvents should be processed over this SubChain.

Returns:

A new OutputProcessorChain

Throws:

XMLStreamException - thrown when a streaming error occurs

XMLSecurityException - thrown when a Security failure occurs

createSubChain

public OutputProcessorChain createSubChain(OutputProcessor outputProcessor,
                                           XMLSecStartElement parentXMLSecStartElement)
                                    throws XMLStreamException,
                                           XMLSecurityException

Specified by:

createSubChain in interface OutputProcessorChain

Throws:

XMLStreamException

XMLSecurityException
