Package org.forgerock.openig.filter
Class ChainHandlerHeaplet
java.lang.Object
org.forgerock.openig.heap.GenericHeaplet
org.forgerock.openig.filter.ChainHandlerHeaplet
- All Implemented Interfaces:
Heaplet
A chain of zero or more filters and one handler. The chain is responsible for
dispatching the request to each filter in the chain, and finally the handler.
When a chain dispatches a request to a filter, it creates a "subchain" (a subset of this chain, which contains the remaining downstream filters and handler), and passes it as a parameter to the filter. For this reason, a filter should make no assumptions or correlations using the chain it is supplied with when invoked.
A filter may elect to terminate dispatching of the request to the rest of the chain by not
calling chain.handle(Context, Request)
and generate its own response or dispatch to a
completely different handler.
