Class InvokeBinding

java.lang.Object
  org.jbpm.wire.binding.InvokeBinding

All Implemented Interfaces:

Binding

public class InvokeBinding
extends java.lang.Object
implements Binding

Defines a InvokeOperation

A invoke is defined by a <invoke> xml element.

This element has a attribute "method", which specifies the name of the method to invoke.

This element contains a list of child elements that defines ArgDescriptors. (see WireParser ) This list of ArgDescriptors will be used to create the arguments of the invoked method.

Example

Consider the following class:

 public class Foo {
   String bar = "";
   public void appendToBar(String text) {
     bar += text;
   }
 }

The following Xml declaration will create an object 'o' of class 'Foo' (see ObjectDescriptor), and invoke the method o.appendToBar with the value hello as a parameter.

 <objects>
   <object name='o' class='Foo'>
     <invoke method='appendToBar'>
       <arg>
        <string value='hello' />
       </arg>
     </invoke>
   </object>
 </objects>

The resulting value of o.bar will be hello.
