Uses of Command in org.apache.commons.chain

Subinterfaces of Command in org.apache.commons.chain

interface	Chain A Chain represents a configured list of Commands that will be executed in order to perform processing on a specified Context.
interface	Filter 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 that return Command

Command	CatalogFactory.getCommand(String commandID) Return a Command based on the given commandID.
Command	Catalog.getCommand(String name) Return the Command or Chain associated with the specified name, if any; otherwise, return null.

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

void	Chain.addCommand(Command command) Add a Command to the list of Commands that will be called in turn when this Chain's execute() method is called.
void	Catalog.addCommand(String name, Command command) Add a new name and associated Command or Chain to the set of named commands known to this Catalog, replacing any previous command for that name.

Uses of Command in org.apache.commons.chain.generic

Classes in org.apache.commons.chain.generic that implement Command

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

Methods in org.apache.commons.chain.generic that return Command

protected Command

LookupCommand.getCommand(Context context) Return the Command instance to be delegated to.

Uses of Command in org.apache.commons.chain.impl

Classes in org.apache.commons.chain.impl that implement Command

class

ChainBase Convenience base class for Chain implementations.

Fields in org.apache.commons.chain.impl declared as Command

protected Command[]

ChainBase.commands The list of Commands configured for this Chain, in the order in which they may delegate processing to the remainder of the Chain.

Methods in org.apache.commons.chain.impl that return Command

Command

CatalogBase.getCommand(String name) Return the Command associated with the specified name, if any; otherwise, return null.

Methods in org.apache.commons.chain.impl with parameters of type Command

void	ChainBase.addCommand(Command command) See the Chain JavaDoc.
void	CatalogBase.addCommand(String name, Command command) Add a new name and associated Command to the set of named commands known to this Catalog, replacing any previous command for that name.

Constructors in org.apache.commons.chain.impl with parameters of type Command

ChainBase(Command command)
Construct a Chain configured with the specified Command.

ChainBase(Command[] commands)
Construct a Chain configured with the specified Commands.

Uses of Command in org.apache.commons.chain.web
