List of dynamicInvoker() Examples

Examples of dynamicInvoker()

java.lang.invoke.CallSite.dynamicInvoker()
Produces a method handle equivalent to an invokedynamic instruction which has been linked to this call site.
This method is equivalent to the following code:
```
 {@code MethodHandle getTarget, invoker, result; getTarget = MethodHandles.publicLookup().bind(this, "getTarget", MethodType.methodType(MethodHandle.class)); invoker = MethodHandles.exactInvoker(this.type()); result = MethodHandles.foldArguments(invoker, getTarget)}
```
@return a method handle which always invokes this call site's current target
java.lang.invoke.ConstantCallSite.dynamicInvoker()
Returns this call site's permanent target. Since that target will never change, this is a correct implementation of {@link CallSite#dynamicInvoker CallSite.dynamicInvoker}. @return the immutable linkage state of this call site, a constant method handle @throws IllegalStateException if the {@code ConstantCallSite} constructor has not completed
java.lang.invoke.MutableCallSite.dynamicInvoker()
