Examples of org.jboss.dna.graph.request.processor.RequestProcessor

org.jboss.dna.graph.request.processor.RequestProcessor
A component that is used to process and execute {@link Request}s. This class is intended to be subclassed and methods overwritten to define the behavior for executing the different kinds of requests. Abstract methods must be overridden, but non-abstract methods all have meaningful default implementations.
