DynamicMethod (Flux Javadoc. Version 8.2. Released on 31 October 2022.)

All Known Subinterfaces:

DynamicEjbEntityAction, DynamicEjbSessionAction, DynamicJavaAction, DynamicRmiAction, WebServiceAction
```
public interface DynamicMethod
```
Allows arbitrary methods to be called on objects. These objects do not need to implement any specific interface. Note that the listener signature must be set before any arguments are set.
As an example, consider the following method.
```
 public int execute(String s, int i, Long l)
 
```
To invoke this method with arguments "hello", 42, 100, call the following methods.
```
 setListenerSignature("execute(String, int, Long)");
 setArgument(0, "hello");
 setArgument(1, 42);
 setArgument(2, new Long(100));
 
```
