public class ProcessingContainer_Impl
extends ProcessingContainer
implements RunnableContainer

Manages a pool of CasProcessor instances. Provides access to CasProcessor instance to Processing Thread. Processing threads check out an instance of Cas Processor and when done invoking its process() method return it back to pool. The container aggregates counts and totals on behalf of all instances of Cas Processor. It also manages error and restart thresholds for Cas Processors as a group. Errors are aggregated for all instances of Cas Processor as a group NOT individually. The container takes appropriate actions when threshold are exceeded. What action is taken depends on declaritive specification in the cpe descriptor.
