<T> static T getOrCreate(Object self, String key, Closure<T> create)

Retrieves a value from any object that supports the subscript operators (square bracket notation, implemented by the getAt/putAt methods). If there is no value for the given key, then the create closure is executed and its return value is set on the object for the key, and returned to the calling code.

   assert !myObject['someProperty']
   def result = map.getOrCreate('someProperty') { ->
     return 13
   }
   assert result == 13
   assert myObject['someProperty'] == 13
 

Parameters:

self

key

Returns:

The value stored in the object by key.
