Class CommandRegistryImpl<C extends Command>

java.lang.Object

org.kie.workbench.common.command.registry.command.CommandRegistryImpl<C>

All Implemented Interfaces:

CommandRegistry<C>, DynamicRegistry<C>, Registry<C>, SizeConstrainedRegistry

public class CommandRegistryImpl<C extends Command>
extends Object
implements CommandRegistry<C>

The default generic implementation for the CommandRegistry type. It's implemented for achieving an in-memory and lightweight registry approach, don't do an overuse of it. Note: The Stack class behavior when using the iterator is not the expected one, so used ArrayDeque instead of an Stack to provide right iteration order.
