NAME

SoBoolOperation -

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.

Detailed Description

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.

Member Enumeration Documentation

enum SoBoolOperation::OperationEnumeration of available boolean logic operators.

Enumerator:

CLEAR
Always set SoBoolOperation::output to FALSE, no matter the input values.
SET
Always set SoBoolOperation::output to TRUE, no matter the input values.
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
