# The OCL Standard Library

This documentation on the OCL Standard Library is auto-generated from the org.eclipse.ocl.pivot/model/OCL-2.5.oclstdlib that defines the behaviour of the Pivot evaluator and the Xtext editors. It is similar to the OCL 2.4 functionality. It is a prototype of functionality for OCL 2.5 where the use of models may eliminate ambiguities.

The library support for the Ecore and UML bindings in Luna has been upgraded so that the available operations are similar to those documented here for the Pivot binding.
