Uses of Command in org.apache.commons.chain

Subinterfaces of Command in org.apache.commons.chain

Modifier and Type	Interface	Description
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	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.
