Wizzi Model instances

A Wizzi Model instance is an in memory javascript object that acts as a context object in a Wizzi Production.

It is an instance of a Wizzi Model DOM and is created by a Wizzi Model factory during a Wizzi Model loading operation, after an mTree has been loaded from an ITTF Document.

To be loaded in a Wizzi Model instance an mTree must be conformant to the Wizzi Schema of the model.

Wizzi Model factory

The javascript module {schema-name}-factory.g.js exports the method 'createLoadModel', that is an HOF that returns the 'loadModel' function. It must be called passing the 'wizzi' object.
