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. Enumeration values: 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 (  )  [protected]

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.
