Class	Description
Catalog<C>	A Catalog is a collection of named Commands (or Chains) that can be used to retrieve the set of commands that should be performed based on a symbolic identifier.
CatalogBase<C>	Simple in-memory implementation of Catalog.
CatalogFactory<C>	A CatalogFactory is a class used to store and retrieve Catalogs.
CatalogFactoryBase<C>	A simple implementation of CatalogFactory.
Chain<C>	A Chain represents a configured list of Commands that will be executed in order to perform processing on a specified Context.
ChainBase<C>	Convenience base class for Chain implementations.
Command<C>	A Command encapsulates a unit of processing work to be performed, whose purpose is to examine and/or modify the state of a transaction that is represented by a Context.
ConfigParser	Class to parse the contents of an XML configuration file (using Commons Digester) that defines and configures commands and command chains to be registered in a Catalog.
ConfigRuleSet	Digester RuleSet for configuring Chain of Responsibility command chains, and adding them to an appropriate Catalog.
Context	A Context represents the state information that is accessed and manipulated by the execution of a Command or a Chain.
ContextBase	Convenience base class for Context implementations.
CopyCommand<C>	Copy a specified literal value, or a context attribute stored under the fromKey (if any), to the toKey.
DispatchCommand<C>	An abstract base command which uses introspection to look up a method to execute.
DispatchLookupCommand<C>	This command combines elements of the LookupCommand with the DispatchCommand.
Filter<C>	A Filter is a specialized Command that also expects the Chain that is executing it to call the postprocess() method if it called the execute() method.
LookupCommand<C>	Look up a specified Command (which could also be a Chain) in a Catalog, and delegate execution to it.
RemoveCommand<C>	Remove any context attribute stored under the fromKey.
