/**
|
|
* Interface for a model and expression transformation.<br>
|
|
*
|
|
* Implementing classes provide a combined model and expression transformation, allowing the calculation
|
|
* of a (potentially simpler) expression in the transformed model to calculate the result of the
|
|
* original expression in the original model.<br>
|
|
*
|
|
* The general idea is the following sequence of calls:<br>
|
|
*
|
|
* {@code ModelExpressionTransformation t = ...;}<br>
|
|
* {@code StateValues resultTransformed = check t.getTransformedExpression() in t.getTransformedModel()}<br>
|
|
* {@code StateValues result = t.projectToOriginalModel(resultTransformed);}
|
