Description copied from interface: IGrammarConstraintProvider

Returns all constraints form this grammar. If a constraint belongs to multiple ConstraintContexts, it is important to call this method to ensure there is inly one instance fo this constraint.

Specified by:

getConstraints in interface IGrammarConstraintProvider

getConstraints
