All Implemented Interfaces:

Guard, SlotGuard, ValueGuard

public final class AnyGuard

extends BaseGuard

Safe: The "any" guard behavior -- don't worry, be happy.

As a ValueGuard, accepts everything without any coercion (the identity coercion). As a SlotGuard, makes a coercion-free settable slot. The object named "any" delegates to the one AnyGuard.
