public final Class MhUtil

extends Object
Class Inheritance
Imports
java.lang.invoke.MethodHandle, .MethodHandles, .MethodType, .VarHandle
Static factories for certain VarHandle/MethodHandle variants.

Some methods take no receiver argument. In these cases, the receiver is the lookup class.

The methods will throw an InternalError if the lookup fails.

Here is an example of how one of these methods could be used:

lang=java static MethodHandle BAR_HANDLE = MhUtil.findVirtual(MethodHandles.lookup(), Foo.class,"bar",MethodType.methodType(int.class)); 
                lang=java
static MethodHandle BAR_HANDLE =
        MhUtil.findVirtual(MethodHandles.lookup(),
                Foo.class,"bar",MethodType.methodType(int.class));
