Attributes

Remarks

Produces a method handle for a reflected constructor. The type of the method handle will be that of the constructor, with the return type changed to the declaring class. The method handle will perform a newInstance operation, creating a new instance of the constructor's class on the arguments passed to the method handle.

If the constructor's accessible flag is not set, access checking is performed immediately on behalf of the lookup class.

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

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