modelgraph

Module modelgraph

 class modelgraph.modelgraph.ModelGraph(**kwargs)  

Bases: pysbs.modulegraph.modulegraph.ModuleGraph

ModelGraph is the Model specialized graph. It is derived from base class ModuleGraph. It handle all specific methods and properties of the Model Graph.

 addGraphAnnotation(aKey: str, aValue) → pysbs.modulegraph.moduleannotation.ModuleAnnotation  

Create an Annotation object and add it to the given graph Annotation handle graph information attributes like description, author, tags…

Parameters:
  • aGraph (ModuleGraph) – the graph where the node will be created
  • aKey (str) – the key word, title, path of the annotation, can be ‘description’, ‘author’ …
  • aValue (str) – the string value of the annotation
Returns:

annotation obj

Return type:

ModuleAnnotation

 connectNodes(aNodeLeft: pysbs.modulegraph.modulenode.ModuleNode, aNodeRight: pysbs.modulegraph.modulenode.ModuleNode, aOutputIdentifer: str = None, aInputIdentifer: str = None) → pysbs.modulegraph.moduleconnection.ModuleConnection  

Connect two nodes by their outputs to inputs, in model graph all inputs are operands. If output and input identifier are not set first of each will be used. Currently there is no type check during the connection, so as long as the output and input exists the connection will be done but could be not valid for the evaluation.

Parameters:
  • aNodeLeft (ModuleNode) – the left node
  • aNodeRight (ModuleNode) – the right node, which received connection
  • aOutputIdentifer (str) – the output pin’s identifier, in the case where the left node has several output
  • aInputIdentifer (str) – the input pin’s identifier, in the case where the right node has several input
Returns:

the connection object

Return type:

ModuleConnection

 createNode(aGraph: modulegraph.ModuleGraph, aNodeId: str, aPos=(0, 0, 0))  

Top def to create an atomic node (not an instance) by given a node id createNode(aModelgraph, “Structure::NodeBool”)

Parameters:
  • aNodeId – the path id of the node
  • aPos – a x, y, z position value
Returns:

ModuleNode

 exposeNode(aNode: pysbs.modulegraph.modulenode.ModuleNode, aIdentifier: str, aDescription: str = '', aInGroup: str = '', aDisplayName: str = '', aGammaType: str = '', aGraphDefinitionId: str = None, aSoftRange=None, aHardRange=None) → pysbs.modulegraph.moduleparaminput.ModuleParamInput  

Expose as a graph input parameter a constant node

Parameters:
  • aGraph (ModuleGraph) – the graph where the input parameter will be created
  • aNode (ModuleNode) – the constant node to exposed as graph input
  • aIdentifier (str) – the identifier of the graph input parameter
  • aDescription (str) – Graph input description
  • aInGroup (str) – Graph input group
  • aDisplayName (str) – Graph input display name
  • aGammaType (str) – Graph input gamma type
  • aSoftRange (list) – a soft range for the graph parameter
  • aHardRange (list) – a hard range for the graph parameter
Returns:
