Method Detail

of
public static Formula of(Formula leftOperand, Formula rightOperand)
Construct a LTL-equivalent formula for (leftOperand)R(rightOperand). The method examines the operands and might choose to construct a simpler formula. However, the size of the syntax tree is not increased. In order to syntactically construct (leftOperand)R(rightOperand) use the constructor.- Parameters:
leftOperand
- The left operand of the R-operatorrightOperand
- The right operand of the R-operator- Returns:
- a formula equivalent to (leftOperand)R(rightOperand)
