Direct Known Subclasses:

AdapterCaster, AuxiliaryCaster

public abstract class DistinctCaster
extends CasterTorso

A concret caster client that can handle commands as found in its KEY_HANDLE list. Additionally, commands found in the KEY_DENY list are never handled. For commands not found in either list, the subclass has to be more specific on the concrete implementation of the handles(stella.CommandEvent) method.

Method Detail

init

public void init()

On init, we construct positive and negative lists.

Specified by:

init in interface Initializable

Overrides:

init in class CasterTorso

handles

public boolean handles(CommandEvent ce)

We look if the class we are asked for is in the positive or negative list. If not, we call the abstract method defaultHandles(stella.CommandEvent)

defaultHandles

public abstract boolean defaultHandles(CommandEvent ce)

For classes not in the deny or allow list.

classList

public static List<Class<? extends CommandEvent>> classList(String comma)

Constructs a list of command events from a comma separated string.
