Method Detail

filterAttached

public void filterAttached(com.vordel.precipitate.SolutionPack ctx,
                  Entity entity)
                    throws EntityStoreException

Description copied from class: FilterContainer

Called on a filter's container when the filter is configured. Any domain-specific initialisation of the filter container can be done at this point. This will be called at least once when the filter attaches.

Overrides:

filterAttached in class FilterContainer

Parameters:

ctx - configuration context for the filter attached to this container.

Throws:

EntityStoreException

filterDetached

public void filterDetached()

Overrides:

filterDetached in class FilterContainer

invoke

public abstract boolean invoke(Circuit c,
             Message m)
                        throws CircuitAbortException

invoked by circuit to act on a message

Parameters:

c - The Circuit context

m - The message

Returns:

predicate indicating success of filter execution

Throws:

CircuitAbortException

getCategory

public java.lang.String getCategory()

Get the category of this processor

Returns:

The category

logFatal

public void logFatal(Message m,
            java.lang.String circuitName)
              throws CircuitAbortException

Default action for fatal logging event

Throws:

CircuitAbortException

logFailure

public void logFailure(Message m,
              java.lang.String circuitName)
                throws CircuitAbortException

Default action for failure logging event

Throws:

CircuitAbortException

logSuccess

public void logSuccess(Message m,
              java.lang.String circuitName)
                throws CircuitAbortException

Default action for a successful logging event

Throws:

CircuitAbortException

logMessagePayload

public void logMessagePayload(Message m,
                     java.lang.String circuitName,
                     com.vordel.log.LogFormatter formatter)
                       throws java.io.IOException,
                              com.vordel.log.LoggingException

Default action for a payload logging event

Throws:

java.io.IOException

com.vordel.log.LoggingException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

report

protected final void report(java.lang.String msg,
          java.lang.Throwable t)

report

protected final void report(java.lang.String msg)

getLogMask
