The SoBoolOperation engine evaluates expressions of boolean logic.
The multivalue fields SoBoolOperation::a and SoBoolOperation::b are combined according to the operations set in SoBoolOperation::operation, with the resulting TRUE or FALSE value set on SoBoolOperation::output.
Enumeration of available boolean logic operators.
| Enumerator | |
|---|---|
| CLEAR | Always set SoBoolOperation::output to |
| SET | Always set SoBoolOperation::output to |
| A | Output result = SoBoolOperation::a |
| NOT_A | Output result = ! SoBoolOperation::a |
| B | Output result = SoBoolOperation::b |
| NOT_B | Output result = ! SoBoolOperation::b |
| A_OR_B | r = a || b |
| NOT_A_OR_B | r = !a || b |
| A_OR_NOT_B | r = a || !b |
| NOT_A_OR_NOT_B | r = !a || !b |
| A_AND_B | r = a && b |
| NOT_A_AND_B | r = !a && b |
| A_AND_NOT_B | r = a && !b |
| NOT_A_AND_NOT_B | r = !a && !b |
| A_EQUALS_B | r = a==b |
| A_NOT_EQUALS_B | r = ! a==b |
