This method finds the state function with the given name in the current model. It is useful especially when the model was loaded from a file using ImportModel(String).

All non-empty names in the model must be unique, otherwise an instance of IloException is thrown. Similarly an instance of IloException is thrown when a state function with the given name does not exist.

The first call of GetIStateFunction may be slower because a searchable data structure must be built first. Once it is built, the function is fast (time complexity O(n) where n is the length of the name).

Note that name aliases cannot be used in this method as described in the section "Statements > Aliasing" of the CP Optimizer File Format Reference Manual.
