All Implemented Interfaces:

IExternalActivity

public class GetObjectAtActivity
extends AbstractExternalActivity

The GetObjectAtActivity allows a Brahms active instance to retrieve the java object at a given index in an array of java.io.Serializable. The Brahms java activity declaration takes three parameters:

• array - A java.io.Serializable variable bound to the array.
• index - The index into the array.
• javaObject - An unbound java.io.Serializable variable that will be bound to the object at the given index of the array.
• result - An unbound boolean variable that will be given the value true if the activity completes successfully
