Interface ObjectKey<O>

Type Parameters:
O - The type of object that the key references
All Known Implementing Classes:
ExtensionKey, ExtensionPointKey, FactoryParametersKey, PluginInfoKey, ServletWrapperKey
public interface ObjectKey<O>
Instances of object keys should be something that uniquely identifies an object that has been defined by an extension. Object keys are mainly used to lookup in which file a certain object has been defined (see ExtensionsManager.getFileByObjectKey(ObjectKey)) and/or to get information about the object itself (see ExtensionsFile.getObjectForKey(ObjectKey))

It is up to the actual implementations to decide what actually makes up a key that can be used to identify an object. Implementors of this interface should implement equals() and hashCode() methods to only match with it's own class. Implementations should be immutable.
