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

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

Member Function Documentation

SoType SoBoolOperation::getClassTypeId ( void  )
static

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

Reimplemented from SoEngine.

SoType SoBoolOperation::getTypeId ( void  ) const
virtual

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

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
SoGroup * group = (SoGroup *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

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

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

Reimplemented from SoEngine.

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

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

Reimplemented from SoEngine.

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

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

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

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

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.
