Returns the AbstractFactory installed on this context.

Usage

From source file:org.eclipse.e4.emf.internal.xpath.NullEStructuralFeaturePointer.java

@Override
public NodePointer createPath(JXPathContext context) {
    NodePointer newParent = parent.createPath(context);
    if (isAttribute()) {
        return newParent.createAttribute(context, getName());
    }/*  w w  w  .j  a  v a 2s . c om*/
    if (parent instanceof NullPointer && parent.equals(newParent)) {
        throw createBadFactoryException(context.getFactory());
    }
    // Consider these two use cases:
    // 1. The parent pointer of NullPropertyPointer is
    //    a PropertyOwnerPointer other than NullPointer. When we call
    //    createPath on it, it most likely returns itself. We then
    //    take a PropertyPointer from it and get the PropertyPointer
    //    to expand the collection for the corresponding property.
    //
    // 2. The parent pointer of NullPropertyPointer is a NullPointer.
    //    When we call createPath, it may return a PropertyOwnerPointer
    //    or it may return anything else, like a DOMNodePointer.
    //    In the former case we need to do exactly what we did in use
    //    case 1.  In the latter case, we simply request that the
    //    non-property pointer expand the collection by itself.
    if (newParent instanceof EStructuralFeatureOwnerPointer) {
        EStructuralFeatureOwnerPointer pop = (EStructuralFeatureOwnerPointer) newParent;
        newParent = pop.getPropertyPointer();
    }
    return newParent.createChild(context, getName(), getIndex());
}
