Dumping the BeanShell namespace in a rule

[#1]

Many times, in a rule, you have no idea what are all the variables that are available to you. The following code snippet will dump all the variables available in the beanshell namespace for the currently executing rule:

UPDATE (1/14/2015): Added check for transient variable name which is a reserved word in Java. See red below.

<Rule name='Namespace'>

  <Source>

System.out.println("Beanshell namespace:");

for (int i=0; i&lt; this.variables.length; i++){

   String name = this.variables[i];

if ("transient".equals(name)) { continue; }

   Object value = eval(name);

   if (value == void)

       print(name + " = void");

   else if (value == null)

       print(name + " = null");

    else

       print (name + ":" + value.getClass().getSimpleName() + " = " + value);

}

  </Source>

</Rule>

As an example, when adding the code above to a buildmap rule, I see the following printed out:

Beanshell namespace:

state: HashMap = {}

context: InternalContext = sailpoint.server.InternalContext@ceb3c0

schema: Schema = sailpoint.object.Schema@630f2f[id=ff8080813fcad43c013fcad460590017,name=<null>]

application: Application = sailpoint.object.Application@87d5ce[id=ff8080813fcad43c013fcad460550015,name=PAM]

bsh: XThis = 'this' reference (XThis) to Bsh object: NameSpace: Bsh Object (bsh.NameSpace@1e43069)
