Attributes

Remarks

Makes a direct method handle to m, if the lookup class has permission. If m is non-static, the receiver argument is treated as an initial argument. If m is virtual, overriding is respected on every call. Unlike the Core Reflection API, exceptions are <em>not</em> wrapped. The type of the method handle will be that of the method, with the receiver type prepended (but only if it is non-static). If the method's accessible flag is not set, access checking is performed immediately on behalf of the lookup class. If m is not public, do not share the resulting handle with untrusted parties.

The returned method handle will have MethodHandle#asVarargsCollector variable arity if and only if the method's variable arity modifier bit (0x0080) is set.

If m is static, and if the returned method handle is invoked, the method's class will be initialized, if it has not already been initialized.
