Package org.eclipse.xtext.xbase.jvmmodel

Class AbstractModelInferrer

java.lang.Object

org.eclipse.xtext.xbase.jvmmodel.AbstractModelInferrer

All Implemented Interfaces:

IJvmModelInferrer

public abstract class AbstractModelInferrer
extends java.lang.Object
implements IJvmModelInferrer

A base dispatch class to be subclassed by clients. It allows subclasses to use Xtend's dispatch methods in order to avoid explicit tree navigation and instanceof checking. see also IJvmModelInferrer

Since:

2.7

Method Detail

infer

public void infer(org.eclipse.emf.ecore.EObject e,
                  IJvmDeclaredTypeAcceptor acceptor,
                  boolean preIndexingPhase)

Description copied from interface: IJvmModelInferrer

This method is called at two different times in a resource's life-cycle, reflected by whether {preIndexingPhase} is set to true or false. When set to true everything is still in a pre-indexing phase, that means linking hasn't been done yet. In this phase you just need to create the Jvm-elements which should be indexed (i.e. found globally). For regular Xbase expressions only the JvmTypes with the correct qualified name are needed at this point.

You must only infer Jvm elements which directly result from elements contained in the current resource!

When this method is called with preIndexingPhase set to false, you need to do the full inference including setting all links. But still you have to it in a particular order. First you need to create the complete tree structure and make sure you have passed the created JvmTypes to the acceptor. Only pass top level JvmTypes to the acceptor. Only if the tree structure is created and its root types have been passed to the acceptor, you are free to resolve any cross references.

Specified by:

infer in interface IJvmModelInferrer

Parameters:

e - the root element from the parse result

acceptor - an acceptor awaiting derived root JvmDeclaredTypes

preIndexingPhase - whether the call is done in before indexing. During this phase clients may not rely on any global indexing information and only need to provide the information needed by the language's IDefaultResourceDescriptionStrategy. IF not implemented differently this is just the JvmDeclaredTypes with their qualified name, but no members and no other data.
