Enum Class AccessFlag.Location

java.lang.Object

java.lang.Enum<AccessFlag.Location>

java.lang.reflect.AccessFlag.Location

All Implemented Interfaces:

Serializable, Comparable<AccessFlag.Location>, Constable

Enclosing class:

AccessFlag

public static enum AccessFlag.Location
extends Enum<AccessFlag.Location>

A location within a class file where flags can be applied.

Note that since these locations represent class file structures rather than language structures, many language structures, such as constructors and interfaces, are not present.

Since:

20
