Process binary operation with values v1 and v2. For unary operation the is invalid. The result of the operation is returned in the parameter v1.
- Parameters
-
| op | operation name |
| v1 | first argument (not valid for unary prefix operations) |
| v2 | second argument (not valid for unary postfix operations) |
- Returns
- error code (QtxEvalExpr::Error)
Implements QtxEvalSet.

virtual |
Create true or false value from string representation.
- Parameters
-
| str | string representration of the value |
| val | returning value |
- Returns
true if str can be evaluated as custom value and false otherwise (parameter)
Reimplemented from QtxEvalSet.

Operation priority counts from 1. If the operation is impossible, this function returns value <= 0.
- Parameters
-
| op | operation |
| isBin | true if the operation is binary and false if it is unary |
- Returns
- operation priority
