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
