Example 1 with N4JSTypeSystem

use of org.eclipse.n4js.typesystem.N4JSTypeSystem in project n4js by eclipse.

the class ComposedMemberFactory method allTypeRefAreEqual.

/**
 * Compares the return types of the new {@link TMember}.
 * <p>
 * Returns true iff no new composition type is created. That is, all return {@link TypeRef}s of the siblings are

    N4JSTypeSystem ts = cmi.getTypeSystem();
    List<TypeRef> allTypeRefs = cmi.getTypeRefsOfMemberType(METHOD, FIELD, GETTER, SETTER);
    TypeRef siTypeRef = ts.createSimplifiedIntersection(allTypeRefs, cmi.getResource());
    Iterator<TypeRef> typeRefIt = allTypeRefs.iterator();
