• org.apache.commons.chain.impl: Javadoc index of package org.apache.commons.chain.impl.


Package Samples:

• org.apache.commons.chain.impl: The fundamental API contracts for the Chain of Responsibilty Pattern as implemented in this package.  

Classes:

• ContextBase: Convenience base class for org.apache.commons.chain.Context implementations. In addition to the minimal functionality required by the org.apache.commons.chain.Context interface, this class implements the recommended support for Attribute-Property Transparency . This is implemented by analyzing the available JavaBeans properties of this class (or its subclass), exposes them as key-value pairs in the Map , with the key being the name of the property itself. IMPLEMENTATION NOTE - Because empty is a read-only property defined by the Map interface, it may not be utilized as an attribute key or property ...
• AddingCommand: Implementation of org.apache.commons.chain.Command that logs its identifier and and attempts to add a new org.apache.commons.chain.Command to the org.apache.commons.chain.Chain . This should cause an IllegalStateException if the org.apache.commons.chain.Chain implementation subclasses ChainBase .
• CatalogBase: Simple in-memory implementation of org.apache.commons.chain.Catalog . This class can also be used as the basis for more advanced implementations. This implementation is thread-safe.
• DelegatingCommand: Implementation of org.apache.commons.chain.Command that logs its identifier and and delegates to the rest of the chain.
• DelegatingFilter: Implementation of org.apache.commons.chain.Filter that logs its identifier and and delegates to the rest of the chain.
• NonDelegatingFilter: Implementation of org.apache.commons.chain.Filter that logs its identifier and and returns true .
• ExceptionCommand: Implementation of org.apache.commons.chain.Command that logs its identifier and and throws an Exception.
• ExceptionFilter: Implementation of org.apache.commons.chain.Filter that logs its identifier and and throws an Exception.
• NonDelegatingCommand: Implementation of org.apache.commons.chain.Command that simply logs its identifier and returns.
• CatalogFactoryBase: A simple implementation of org.apache.commons.chain.CatalogFactory .
• ChainBase: Convenience base class for org.apache.commons.chain.Chain implementations.
• TestContext: Subclass of ContextBase to exercize the automatic delegation to properties of the Context class.
• TestContextTestCase: Extension of ContextBaseTestCase to validate property delegation.
• CatalogFactoryBaseTestCase: Test case for the CatalogFactoryBase class.
• CatalogBaseTestCase: Test case for the CatalogBase class.
• ContextBaseTestCase: Test case for the ContextBase class.
• ChainBaseTestCase: Test case for the ChainBase class.
