SoEngineOutputData

NAME

SoEngineOutputData -

The SoEngineOutputData class is a container for a prototype set of outputs.

This class is instantiated once for each class of objects which use outputs, and which needs to be able to import and export them.

Detailed Description

The SoEngineOutputData class is a container for a prototype set of outputs.

This class is instantiated once for each class of objects which use outputs, and which needs to be able to import and export them.

Each output of a class is stored with the name and type it has been given within its 'owner' class and a pointer offset to the dynamic instance of the output itself.

It is unlikely that application programmers should need to use any of the methods of this class directly.

Member Function Documentation

void SoEngineOutputData::addOutput (const SoEngine * base, const char * name, const SoEngineOutput * output, SoType type)Add a new output to our internal list.

The name and type will be stored along with a pointer offset between base and output, which will be valid for all instances of the class type of base.

void SoEngineOutputData::addOutput (const SoNodeEngine * base, const char * name, const SoEngineOutput * output, SoType type)This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

int SoEngineOutputData::getNumOutputs (void) constReturns the number of outputs contained within this instance.

const SbName & SoEngineOutputData::getOutputName (int index) constReturns the name of the output at index.

SoEngineOutput * SoEngineOutputData::getOutput (const SoEngine * engine, int index) constReturns a pointer to the output at index within the engine instance.

SoEngineOutput * SoEngineOutputData::getOutput (const SoNodeEngine * engine, int index) constThis is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

int SoEngineOutputData::getIndex (const SoEngine * engine, const SoEngineOutput * output) constReturns the internal index value of output in engine. If output is not part of engine, it returns -1.

int SoEngineOutputData::getIndex (const SoNodeEngine * engine, const SoEngineOutput * output) constThis is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

const SoType & SoEngineOutputData::getType (int index) constReturns the type of the output at index.
