- Fixed wrong nomenclature (DISJUNCTION vs. CONJUNCTION) - Removed impossible cases from BooleanExpression Transformer -- A root expression of a constraint may never be anything other than a relational expression, an attribute expression returning a boolean value or a boolean literal value. Exceptions to this are only allowed within Boolean expressions of Stream/Filter-Operations.
…negated relational Expressions - TODO: Finish normalizer function
…gated relational expressions.
- added new function (incomplete) the normalizes the relational operator and inserts a symbolic variable reflecting the outcome of the relational expression - TODO: Finish function
…ting the new transformation method. - NOTE: This does not mean that the current state is error free! Needs testing using the current test suite.
