SoEngineOutput::SoEngineOutput (void )

Constructor. The SoEngineOutput will initially not be contained within an SoEngine nor will it have any slave fields attached.

See also

SoEngineOutput::~SoEngineOutput (void ) [virtual]

Destructor.

SoType SoEngineOutput::getConnectionType (void ) const

Returns the type of the engine output.

int SoEngineOutput::getForwardConnections (SoFieldList & fl) const

Adds all slave fields connected to this output to fl. Returns the number of slaves.

See also

void SoEngineOutput::enable (const SbBool flag)

Sets the enabled flag. If output is disabled, the fields connected to this output will not be changed when the engine is evaluated.

See also

SbBool SoEngineOutput::isEnabled (void ) const

Returns status of the enabled flag.

See also

SoEngine * SoEngineOutput::getContainer (void ) const

Returns the engine containing this output. If the engine containing this output is a NodeEngine, this method returns NULL.

See also

SoNodeEngine * SoEngineOutput::getNodeContainer (void ) const

Returns the node engine containing this output. If the engine containing this output is not a NodeEgine, this method returns NULL.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since

SbBool SoEngineOutput::isNodeEngineOutput (void ) const

Returns TRUE if the container is a NodeEngine.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since

void SoEngineOutput::setContainer (SoEngine * engine)

Sets the engine containing this output.

See also

void SoEngineOutput::setNodeContainer (SoNodeEngine * nodeengine)

Sets the NodeEngine containing this output.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since

void SoEngineOutput::addConnection (SoField * f)

Adds f to the list of connections from this output.

Adds 1 to the reference count of the container engine.

See also

void SoEngineOutput::removeConnection (SoField * f)

Removes f from the list of connections from this output.

Subtracts 1 from the reference count of the container engine. If the reference count reaches zero (which will happen if this was the last connection and the application programmer did not explicitly ref the engine), the container engine will be deallocated.

See also

int SoEngineOutput::getNumConnections (void ) const

Returns the number of fields in the list of connections.

See also

SoField * SoEngineOutput::operator[] (int i) const

Returns the field at index i in the list of connections.

Please note that this might not be the same field as the one the output was originally connected to, since a field converted might have been inserted to converted the output to match the field type.

See also

void SoEngineOutput::prepareToWrite (void ) const

Disables notifications on fields connected to this output. This is done before the engine is evaluated, since the fields we are going to write into have already been notified.

See also

void SoEngineOutput::doneWriting (void ) const

Restores the notification flags on fields connected to this output after evaluating.

See also

void SoEngineOutput::touchSlaves (SoNotList * nl, SbBool donotify)

Notify the fields attached to this engine output that the output value has changed.

If donotify is TRUE, propagate the notification to the fields. Otherwise just mark the fields 'dirty' for re-evaluation.

Note that this method is not part of the original Open Inventor API.

SoFieldContainer * SoEngineOutput::getFieldContainer (void )

Convenience method that returns a field container. This method can be used both for NodeEngine and Engine outputs.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
