Class GenericExecContextPluginFactory<ExecContextPluginInterface extends org.azyva.dragom.execcontext.plugin.ExecContextPlugin>

java.lang.Object

org.azyva.dragom.execcontext.plugin.support.GenericExecContextPluginFactory<ExecContextPluginInterface>

Type Parameters:

ExecContextPluginInterface - ExecContextPlugin sub-interface returned by the ExecContextPluginFactory.

All Implemented Interfaces:

org.azyva.dragom.execcontext.plugin.ExecContextPluginFactory<ExecContextPluginInterface>

public class GenericExecContextPluginFactory<ExecContextPluginInterface extends org.azyva.dragom.execcontext.plugin.ExecContextPlugin>
extends Object
implements org.azyva.dragom.execcontext.plugin.ExecContextPluginFactory<ExecContextPluginInterface>

Generic implementation of ExecContextPluginFactory based on a simple class that implements (a sub-interface of) ExecContextPlugin.

ExecContextPlugin instances are obtained from ExecContextPluginFactory. But in many cases an ExecContextPlugin can be instantiated by creating an instance of a class with a constructor having an ExecContext as its only argument. This generic class simply wraps such a class inside a simple ExecContextPluginFactory.

This class ensures that for a given ExecContextPlugin implementation class and ExecContext, the same ExecContextPlugin instance is returned. This to make it so that if a single ExecContextPlugin implementation class that extends multiple ExecContextPlugin interfaces, the same instance is actually used for all of them (for a given ExecContext), which is generally what such an implementation class would expect.
