The request's publication object
The publication object, an IRequestPublication provides application-specific functionality hooks.
interaction
(Attribute)

response
(Attribute)
The request's response object
Return an IPublisherResponse for the request.
principal
(Attribute)
The authenticated principal
* = required
setPublication(publication)
Set the request's publication object
traverse(object)
Traverse from the given object to the published object
The published object is returned.
The following hook methods on the publication will be called:
- callTraversalHooks is called before each step and after the last step.
- traverseName to actually do a single traversal
retry()
Return a retry request
Return a request suitable for repeating the publication attempt.
processInputs()
Do any input processing that needs to be done before traversing
This is done after construction to allow the publisher to handle errors that arise.
getTraversalStack()
Return the request traversal stack
This is a sequence of steps to traverse in reverse order. They will be traversed from last to first.
setTraversalStack(stack)
Change the traversal stack.
See getTraversalStack.
getPositionalArguments()
Return the positional arguments given to the request.
close()
Release resources held by the request.
setPrincipal(principal)
Set the principal attribute.
It should be IPrincipal wrapped in its AuthenticationService's context.
hold(held)
Hold a reference to an object until the request is closed.
The object should be an IHeld. If it is an IHeld, its release method will be called when it is released.
