Class ImmutableExtensionPointCollection<T extends ExtensionPoint<?>>

java.lang.Object

com.inductiveautomation.ignition.gateway.config.ImmutableExtensionPointCollection<T>

All Implemented Interfaces:

ExtensionPointCollection<T>

public class ImmutableExtensionPointCollection<T extends ExtensionPoint<?>>
extends Object
implements ExtensionPointCollection<T>

An immutable collection of extension points. See build(ResourceType, ModuleManager, ExtensionPoint[]) for a way to build an instance of this class. This class can be created very early in the lifecycle of a gateway (after modules are loaded, but before they are set up or started). This because as of 8.3, modules have a static lifecycle fixed to the gateway, so we know that the set of possible extension points cannot change.

Uses a "hollywood style" method of collecting extension point implementations. See GatewayModuleHook.getExtensionPoints();
