Usage

From source file:auto.parse.processor.AutoParseProcessor.java

private void findLocalAndInheritedMethods(TypeElement type, List<ExecutableElement> methods) {

    if (type.getSuperclass().getKind() != TypeKind.NONE) {

        // method after any interfaces that declared it.

    }
    // Add each method of this class, and in so doing remove any inherited method it overrides.
    // This algorithm is quadratic in the number of methods but it's hard to see how to improve
    // that while still using Elements.overrides.
