In Groovy we can invoke an implicit call() method on a Groovy object. We can leave out the call method name and just use (). We can use meta programming to add an implementation for the call() method to a class. In the following example script we add an implementation for the call() method with a single parameter to the String class. The implementation returns the element found at the range specified by the argument when we invoke the method:
  • 6
  • 0
  • 631
  • 329
