Interface IExtensionSingleton

All Known Implementing Classes:

CSSModuleBuilder, LessModuleBuilder

public interface IExtensionSingleton

Aggregator extensions implementing this interface will be treated as singletons when the extensions are created declaratively (e.g. from plugin.xml). This means that only one instance of the class will be created regardless of how many extension points use the class.

Note that the IExtensionInitializer.initialize(IAggregator, IAggregatorExtension, IExtensionRegistrar) method will still be called once for each extension point that is initialized (although, not concurrently) so extensions implementing this interface need to take steps to avoid duplicating work in their initializers.
