Package nl.openedge.baritus.interceptors Description

Interceptors.

Interceptors provide a means to encapsulate cross-cutting code that is executed on pre-defined points in the line of execution.

Interceptors can be used to decorate the normal execution. Also, by throwing FlowExceptions, interceptors can alter the flow of execution. An interceptor can throw a FlowException if it wants Baritus to stop normal processing and go to the given declared view (using ReturnNowFlowException) such as 'error', or dispatch to an arbitrary - non declared - URL (using DispatchNowFlowException) location.
