Using the Locking System

Here we will have a look at the Locking System. We will learn how to lock and unlock objects using locks. Locks are used to make sure objects are only used by one owner.

Getting ready

The Locking System doesn't need anything, as it itself is just virtual.

How to do it...

There are three phases to locking: locking, checking and unlocking.

Create a lock

We will now create a lock:

1. Create a new workflow and add a scriptable task.

2. Add the following variables as input:

   Name	Type	Section	Use
   object	String	IN	Any string
   owner	String	IN	Any string

3. Enter the following script:

   LockingSystem.lockAndWait(object ,owner); 
   

4. Add the workflow Display all Locks at the end.

5. Save and run the workflow. Enter as object any string, such as Test and as owner or any other string such as Goofy.

6. Check the logs.

Check for lock

We will now check if an object is locked:

1. Create a new workflow and add a scriptable task.

2. Add the following variables as input:

   Name

   Type
