Method Detail

withConstraint

public ConstraintFormulaSet withConstraint(ConstraintFormula constraintFormula)

empty

public static ConstraintFormulaSet empty()

reduce

public BoundSet reduce(TypeSolver typeSolver)

Takes a compatibility assertion about an expression or type, called a constraint formula, and reduces it to a set of bounds on inference variables. Often, a constraint formula reduces to other constraint formulas, which must be recursively reduced. A procedure is followed to identify these additional constraint formulas and, ultimately, to express via a bound set the conditions under which the choices for inferred types would render each constraint formula true.

isEmpty

public boolean isEmpty()
