BackdropPtr GraphElement::addBackdrop ( const string & name = EMPTY_STRING )

inline

Add a Backdrop to the graph.

Definition at line 264 of file Node.h.

NodePtr GraphElement::addGeomNode	(	ConstGeomPropDefPtr	geomPropDef,
		const string &	namePrefix
	)

If not yet present, add a geometry node to this graph matching the given property definition and name prefix.

NodePtr GraphElement::addMaterialNode	(	const string &	name = `EMPTY_STRING`,
		ConstNodePtr	shaderNode = `nullptr`
	)

Add a material node to the graph, optionally connecting it to the given shader node.

NodePtr GraphElement::addNode	(	const string &	category,
		const string &	name = `EMPTY_STRING`,
		const string &	type = `DEFAULT_TYPE_STRING`
	)

inline

Add a Node to the graph.

Parameters

category	The category of the new Node.
name	The name of the new Node. If no name is specified, then a unique name will automatically be generated.
type	An optional type string.

Returns: A shared pointer to the new Node.

Definition at line 194 of file Node.h.

NodePtr GraphElement::addNodeInstance	(	ConstNodeDefPtr	nodeDef,
		const string &	name = `EMPTY_STRING`
	)

inline

Add a Node that is an instance of the given NodeDef.

Definition at line 205 of file Node.h.

string GraphElement::asStringDot ( ) const

Convert this graph to a string in the DOT language syntax. This can be used to visualise the graph using GraphViz (http://www.graphviz.org).

If declarations for the contained nodes are provided as nodedefs in the owning document, then they will be used to provide additional formatting details.

void GraphElement::flattenSubgraphs	(	const string &	target = `EMPTY_STRING`,
		NodePredicate	filter = `nullptr`
	)

Flatten all subgraphs at the root scope of this graph element, recursively replacing each graph-defined node with its equivalent node network.

Parameters

target	An optional target string to be used in specifying which node definitions are used in this process.
filter	An optional node predicate specifying which nodes should be included and excluded from this process.

BackdropPtr GraphElement::getBackdrop ( const string & name ) const

vector<NodePtr> GraphElement::getNodesOfType ( const string & nodeType ) const

inline

Return a vector of nodes in the graph which have a given type.

Definition at line 226 of file Node.h.

void GraphElement::removeBackdrop ( const string & name )
