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

◆ 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.

Output result = SoBoolOperation::a

NOT_A 

Output result = ! SoBoolOperation::a

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::SoBoolOperation ( void )

Default constructor.

◆ ~SoBoolOperation()

SoBoolOperation::~SoBoolOperation ( void )
protectedvirtual

Destructor.

Member Function Documentation

◆ createInstance()

void * SoBoolOperation::createInstance ( void )
static

Creates a new instance of the class type corresponding to the SoType object.

◆ getClassTypeId()

SoType SoBoolOperation::getClassTypeId ( void )
static

This static method returns the SoType object associated with objects of this class.

◆ getFieldData()

const SoFieldData * SoBoolOperation::getFieldData ( void ) const
virtual

Returns the SoFieldData class which holds information about inputs in this engine.

Reimplemented from SoFieldContainer.

◆ getInputDataPtr()

const SoFieldData ** SoBoolOperation::getInputDataPtr ( void )
staticprotected

Returns the SoFieldData class which holds information about inputs in this engine.

◆ getOutputData()

const SoEngineOutputData * SoBoolOperation::getOutputData ( void ) const
virtual

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

Implements SoEngine.

◆ getOutputDataPtr()

const SoEngineOutputData ** SoBoolOperation::getOutputDataPtr ( void )
staticprotected

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

◆ getTypeId()

SoType SoBoolOperation::getTypeId ( void ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Implements SoBase.

Member Data Documentation

◆ a

SoMFBool SoBoolOperation::a

First set of boolean input "signal" values.

◆ b

SoMFBool SoBoolOperation::b

Second set of boolean input "signal" values.

◆ inverse

SoEngineOutput SoBoolOperation::inverse

(SoMFBool) The set of inverse results.

◆ operation

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.

◆ output

SoEngineOutput SoBoolOperation::output

(SoMFBool) The result of each (a[i] operation[i] b[i]) expression.
