Examples with N4ClassDefinition org.eclipse.n4js.n4JS.N4ClassDefinition used on opensource projects

Example 1 with N4ClassDefinition

use of org.eclipse.n4js.n4JS.N4ClassDefinition in project n4js by eclipse.

the class N4JSMemberRedefinitionValidator method checkUnpairedAccessorFilling.

private void checkUnpairedAccessorFilling(MemberMatrix mm, N4ClassifierDefinition definition) {
    if (definition.getDefinedType().isStaticPolyfill() && mm.hasMixedAccessorPair()) {
        FieldAccessor ownedAccessor = (FieldAccessor) Iterables.getFirst(mm.owned(), null);
        if (null == ownedAccessor) {
            // Should not happen, a mixed accessor pair implies at least one owned member
            return;
        }
        if (!(definition instanceof N4ClassDefinition)) {
            // Non-class static polyfills aren't allowed. Validated somewhere else.
            return;
        }
        TClass filledClass = MemberRedefinitionUtils.getFilledClass((N4ClassDefinition) definition);
        if (null == filledClass) {
            // Invalid static polyfill class. Validated somewhere else.
            return;
        }
        // Iterate over all inherited members
        SourceAwareIterator memberIterator = mm.actuallyInheritedAndMixedMembers();
        while (memberIterator.hasNext()) {
            TMember next = memberIterator.next();
            ContainerType<?> containingType = next.getContainingType();
            // Issue an error if the member isn't owned by the filled class
            if (containingType != filledClass) {
                messageMissingOwnedAccessor(ownedAccessor);
            }
        }
    }
}

Example 2 with N4ClassDefinition

use of org.eclipse.n4js.n4JS.N4ClassDefinition in project n4js by eclipse.

the class N4JSSyntaxValidator method checkClassDefinition.

/**
 * Checks that no "with" is used and that list of implemented interfaces is separated with commas and not with
 * keywords. These checks (with some warnings created instead of errors) should help the transition from roles to
 * interfaces. However, they may be useful later on as well, e.g., if an interface is manually refactored into a
 * class or vice versa.
 * <p>
 * Note that "with" is used in Dart for roles, so maybe it is useful to have a user-friendly message instead of a
 * parser error.
