Parameters:

filterCommandName - the command name for which this factory is registered

factory - the factory responsible for creating FilterCommands for the specified name

Returns:

the previous factory associated with commandName, or null if there was no mapping for commandName

unregister

public static FilterCommandFactory unregister(String filterCommandName)

Unregisters the FilterCommandFactory registered for the given command name

Parameters:

filterCommandName - the FilterCommandFactory's filter command name

Returns:

the previous factory associated with filterCommandName, or null if there was no mapping for commandName

isRegistered

public static boolean isRegistered(String filterCommandName)

Checks whether any FilterCommandFactory is registered for a given command name

Parameters:
