Detailed Description

Base class for all music graph nodes in the Silence system.

Nodes can transform silence::Events produced by child nodes. Nodes can produce silence::Events.

virtual void csound::Node::addChild ( Node node) [virtual]
virtual void csound::Node::clear ( ) [virtual]
virtual ublas::matrix<double> csound::Node::createTransform ( ) [virtual]
virtual double& csound::Node::element ( size_t  row,

) [virtual]
virtual ublas::matrix<double> csound::Node::getLocalCoordinates ( ) const [virtual]

Returns the local transformation of coordinate system.

virtual void csound::Node::produceOrTransform ( Score score,
size_t  beginAt,
size_t  endAt,
const ublas::matrix< double > &  compositeCordinates 
) [virtual]

The default implementation does nothing.

Derived nodes that produce notes from scratch should transform them using the composite transformation of coordinate system, which is passed in from the traverse() function.

Reimplemented in csound::Cell, csound::ChordLindenmayer, csound::CounterpointNode, csound::Hocket, csound::MCRM, csound::RemoveDuplicates, csound::Random, csound::Rescale, csound::ScoreNode, and csound::VoiceleadingNode.

virtual void csound::Node::setElement ( size_t  row,
size_t  column,
double  value 
) [virtual]
virtual ublas::matrix<double> csound::Node::traverse ( const ublas::matrix< double > &  globalCoordinates,
Score score 
) [virtual]

The default implementation postconcatenates its own local coordinate system with the global coordinates, then passes the score and the product of coordinate systems to each child, thus performing a depth-first traversal of the music graph.

Reimplemented in csound::Hocket, and csound::Sequence.
