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