The Object Constraint Language (OCL) is a language for describing rules that apply to MOF conform modelling languages like UML. The OCL is a text based language that provides constraint and object query expressions that cannot be expressed by a meta modelling language.

To illustrate the usage of this library, an example web page has been set up here.

npm install --save @stekoe/ocl.js

import {OclEngine} from '@stekoe/ocl.js'

const oclEngine = OclEngine.create()
    .addOclExpression(`
        context Person
            inv: self.name->isNotEmpty()
    `);

const validate = oclEngine.evaluate(anObject)
    .getResult();

Register a new OCL expression to the given OCL instance.

• oclExpression (String): The OCL expression to register.

Evaluate the given object wether it does not violate any of the registered OCL expressions.

• object (Object): The object / instance to test against the registered OCL expressions.
