public static FilterCommandFactory register(java.lang.String filterCommandName,
                                            FilterCommandFactory factory)

Register a FilterCommandFactory responsible for creating FilterCommands for a certain command name. If the factory f1 is registered for the name "jgit://builtin/x" then a call to getCommand("jgit://builtin/x", ...) will call f1(...) to create a new instance of FilterCommand

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(java.lang.String filterCommandName)

Unregister 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(java.lang.String filterCommandName)

Check whether any FilterCommandFactory is registered for a given command name

Parameters:

filterCommandName - the name for which the registry should be checked

Returns:

true if any factory was registered for the name

getRegisteredFilterCommands

public static java.util.Set<java.lang.String> getRegisteredFilterCommands()

Get registered filter commands

Returns:

Set of commandNames for which a FilterCommandFactory is registered

createFilterCommand

public static FilterCommand createFilterCommand(java.lang.String filterCommandName,
                                                Repository db,
