* Usage: |
| jtulach@154 | 25 |
* First method parse must be called with valid logical expression on |
| jtulach@154 | 26 |
* input. |
| jtulach@154 | 27 |
* If it returns zero then it is possible to call method evaluate with |
| jtulach@154 | 28 |
* array of input values as parameter. Method evaluate can be invoked |
| jtulach@154 | 29 |
* many time with different input values. |
| jtulach@52 | 30 |
* Method parse can be called anytime to change logical expression. |
