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.

SYNOPSIS

       #include <Inventor/engines/SoBoolOperation.h>

       Inherits SoEngine.

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::Operation Enumeration 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

Constructor & Destructor Documentation

   SoBoolOperation::SoBoolOperation (void) Default constructor.
   SoBoolOperation::~SoBoolOperation (void) [protected, virtual] Destructor.

Member Function Documentation

   void SoBoolOperation::initClass (void) [static] Sets up initialization for data common to all
       instances of this class, like submitting necessary information to the Coin type system.
       Reimplemented from SoEngine.

Member Data Documentation

   SoMFBool SoBoolOperation::a First set of boolean input 'signal' values.
   SoMFBool SoBoolOperation::b Second set of boolean input 'signal' values.
   SoMFEnum SoBoolOperation::operation Set of boolean logic expressions. Each of these are used
       to combine SoBoolOperation::a with SoBoolOperation::b (for each index value from 0 to the
       last value) to produce the results on the SoBoolOperation::output field.
   SoEngineOutput SoBoolOperation::output (SoMFBool) The result of each (a[i] operation[i] b[i])
       expression.
   SoEngineOutput SoBoolOperation::inverse (SoMFBool) The set of inverse results.
