Class SpecificationSourceImpl

java.lang.Object
  org.apache.tapestry.services.impl.SpecificationSourceImpl

All Implemented Interfaces:

EventListener, ISpecificationSource, ReportStatusListener, ResetEventListener

public class SpecificationSourceImpl
extends Object
implements ISpecificationSource, ResetEventListener, ReportStatusListener

Default implementation of ISpecificationSource that expects to use the normal class loader to locate component specifications from within the classpath.

Caches specifications in memory forever, or until resetEventDidOccur() is invoked.
