org.apache.commons.chain.Context

Packages that use Context

Package	Description
org.apache.commons.chain	The fundamental API contracts for the Chain of Responsibility Pattern as implemented in this package.
org.apache.commons.chain.generic	Concrete implementations of generic Commands that are useful in many different environments, not tied to a particular tier such as Servlets).
org.apache.commons.chain.impl	Convenient base implementations of Chain of Responsibility Pattern contracts from org.apache.commons.chain.

Uses of Context in org.apache.commons.chain

Classes in org.apache.commons.chain with type parameters of type Context

Modifier and Type	Interface	Description
interface	Catalog<C extends Context>	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.
class	CatalogFactory<C extends Context>	A CatalogFactory is a class used to store and retrieve Catalogs.
interface	Chain<C extends Context>	A Chain represents a configured list of Commands that will be executed in order to perform processing on a specified Context.
interface	Command<C extends Context>	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.
interface	Filter<C extends Context>	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.

Methods in org.apache.commons.chain with type parameters of type Context

Modifier and Type	Method	Description
static <C extends Context> CatalogFactory<C>	CatalogFactory.getInstance()	Return the singleton CatalogFactory instance for the relevant ClassLoader.

Classes in org.apache.commons.chain.generic with type parameters of type Context

Modifier and Type	Class	Description
class	CopyCommand<C extends Context>	Copy a specified literal value, or a context attribute stored under the fromKey (if any), to the toKey.
class	DispatchCommand<C extends Context>	An abstract base command which uses introspection to look up a method to execute.
class	DispatchLookupCommand<C extends Context>	This command combines elements of the LookupCommand with the DispatchCommand.
class	LookupCommand<C extends Context>	Look up a specified Command (which could also be a Chain) in a Catalog, and delegate execution to it.
