Major changes according to changes in SAMSON SDK 0.8.0. The SAMSON 0.8.0 release brings major changes in SAMSON and SAMSON SDK. It also improves stability and fixes known issues.

Below are listed the changes in the Python Scripting API per sub-module.

Facade#

Facade.SAMSON#

The getActiveModel function has been renamed to getActiveStructuralModel (samson.Facade.SAMSON.getActiveStructuralModel).

New/updated functions:

  • samson.Facade.SAMSON.importFromFile() function now receives a preferredFolder instead of a preferredLayer;

  • samson.Facade.SAMSON.setActiveStructuralModel()

  • get node at a particular (x, y) position (getAtom, getBond, getNode);

  • get nodes in a rectangle getNodes.

DataModel#

DataModel.Type#

samson.DataModel.Type: small changes and issue fixes.

DataModel.Document#

Folder

Class: samson.DataModel.Document.Folder

samson.DataModel.Document.Layer has been changed to samson.DataModel.Document.Folder.

Layer has been changed to a more general Folder (samson.DataModel.Document.Folder). A Folder object can contain almost any node types, including other folders. Any usage of an active layer (samson.Facade.SAMSON.getActiveLayer()) should be modified to e.g. an active document (samson.Facade.SAMSON.getActiveDocument()). Any other usages of an Layer should be modified to use either a Folder or an active document.

Folder (samson.DataModel.Document.Folder) has parts of the Layer functionality and some new functionality e.g. get lists of nodes of different types.

Document

Class: samson.DataModel.Document.Document.

New functionality:

  • getActiveCamera

  • setActiveCamera

  • getActiveStructuralModel

  • setActiveStructuralModel

  • createGroup

  • groupSelection

  • selectGroupNodes

  • addGroupNodesToSelection

  • removeGroupNodesFromSelection

  • intersectGroupNodesWithSelection

Camera

Class: samson.DataModel.Document.Camera.

New/updated functionality:

  • transform;

  • center - centers the camera around nodes in the provided node indexer (samson.DataModel.DataGraph.NodeIndexer).

DataModel.DataGraph#

Node

Class: samson.DataModel.DataGraph.Node.

New/updated functionality:

  • getNextNode

  • getPreviousNode

  • getDocument

  • canAddChild

  • canAddChildType

  • isOneOf

  • isType

  • isModel

  • isStructuralModel

The structural root (samson.Modeling.StructuralModel.Root) is now hidden and implicit. When creating a structural model (samson.Modeling.StructuralModel.StructuralModel) it is not necessary anymore to add it to the structural root of a Document (samson.DataModel.Document.Document), it will be done implicitly.

Path

Class: samson.Modeling.StructuralModel.Path.
