All Implemented Interfaces:

Supplier<MethodHandle>

Direct Known Subclasses:

public abstract class UnreflectHandleSupplier

implements Supplier<MethodHandle>

Lazy memoized holder for MethodHandles. Defers binding of the method handle until after access checks are suppressed (which happens in a virtual method call after construction) and avoids serialization of MethodHandle.
