class Gecode::BoolVar

Describes a boolean variable.

A boolean variable can be either true or false.

Boolean variables are boolean operands and hence respond to everything that Gecode::Bool::BoolOperand responds to. Any constraint found in Gecode::Bool::BoolConstraintReceiver can thereby be placed on boolean variables.
