Umple Active Objects
User Manual [Previous] [Next]
Active Objects
An active object is an object that, when constructed, runs its own thread. This is indicated in Umple by the 'active' keyword followed by a block of code. A collection of active objects, working together, constitute a concurrent system.
Additional Umple features are under development to allow for sending signals to and from concurrent objects.
Example
class A {
name;
active {
System.out.println("Object "+getName()+"is now active");
for (int i = 1; i < 10; i++) {
System.out.println(" "+name+" was here");
Thread.sleep(1000);
}
}
public static void main(String[] argv) {
new A("1");
new A("2");
}
}
