Examples of org.jruby.embed.ScriptingContainer.clear()

org.jruby.embed.ScriptingContainer.clear()
Removes all of the mappings from this map. The map will be empty after this call returns. Ruby variables are also removed from Ruby instance. However, Ruby instance keep having global variable names with null value. This is a short cut method of ScriptingContainer#getVarMap().clear().

         // the result must be a string
         return result != null ? result.toString() : null;
      }
      finally {
         if (container != null)
            container.clear();
      }
