Method Detail

projectOpened

public void projectOpened()

Description copied from interface: ProjectComponent

Invoked when the project corresponding to this component instance is opened.

Note that components may be created for even unopened projects and this method can be never invoked for a particular component instance (for example for default project).

Specified by:

projectOpened in interface ProjectComponent

Overrides:

projectOpened in class CompilerReferenceServiceBase<JavaBackwardReferenceIndexReaderFactory.BackwardReferenceReader>
