Class CaptureDecorator

java.lang.Object

org.forgerock.openig.decoration.helper.AbstractDecorator

org.forgerock.openig.decoration.helper.AbstractHandlerAndFilterDecorator

org.forgerock.openig.decoration.capture.CaptureDecorator

All Implemented Interfaces:

Decorator

public class CaptureDecorator
extends AbstractHandlerAndFilterDecorator

The capture decorator can decorates both Filter and Handler instances. It enables the user to see the messages coming in and out of the decorated object.

Multiple input/output can be intercepted:

• CapturePoint.ALL: Prints all of the messages
• CapturePoint.FILTERED_REQUEST: Prints the outgoing request (Filter only)
• CapturePoint.FILTERED_RESPONSE: Prints the outgoing response
• CapturePoint.REQUEST: Prints incoming + outgoing request
• CapturePoint.RESPONSE: Prints incoming + outgoing response

Notice that camel case is not important: all equals ALL and even AlL. It has to be declared inside of the heap objects section:

     
     {
       "name": "capture",
       "type": "CaptureDecorator",
       "config": {
           "captureEntity": false,
           "captureContext": false
       }
     }
     
 

The capture decorator can be configured to globally enable entity capture using the captureEntity boolean attribute (default to false). To capture the context at the capture point as well, use the captureContext boolean attribute (default to false).

To decorate a component, just add the decorator declaration next to the config element:

     
     {
       "type": "...",
       "capture": [ "FILTERED_REQUEST", "RESPONSE" ],
       "config": { ... }
     }
     
 

Notice that the attribute name in the decorated object has to be the same as the decorator heap object name (capture in our example). A default capture decorator is automatically created when OpenIG starts. It can be overridden in the configuration files if default values are not satisfying.
