C# 클래스 Dynamo.Graph.Workspaces.WorkspaceModel

Clears this workspace of nodes, notes, and connectors.

Creates ModelBase object by given xml data and adds it to corresponding collection of the workspace.

Deletes ModelBase object given by XmlElement from a corresponding collection of the workspace.

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Gets model by GUID which is contained in given Xml data.

Returns model by GUID

Returns appropriate name of workspace for sharing.

Adds a specified collection PresetModel objects to the preset collection of the workspace.

Implement recording node modification for undo/redo.

Updates ModelBase object with given xml data

Deletes AnnotationModel object from annotation collection of the workspace.

Removes a specified PresetModel object from the preset collection of the workspace.

Called when workspace position is changed. This method notifyies all the listeners when a workspace is changed.

Save assuming that the Filepath attribute is set.

Save to a specific file path, if the path is null or empty, does nothing. If successful, the CurrentWorkspace.FilePath field is updated as a side effect

Indicates that the AST for a node in this workspace requires recompilation

Derived workspace classes can choose to override this method to perform clean-up specific to them.

Adds a node to this workspace.

this method creates a new preset state from a set of NodeModels and adds this new state to this presets collection

This method repeatedly shifts subgraphs away vertically from each other when there are any two nodes from different subgraphs overlapping.

Checks if model exists in same group.

This method ensures that all upstream node caches are correct by calling ComputeUpstreamOnDownstream on all source nodes in the graph, this is done in such a way that each node is only computed once.

This function wraps a few methods on the workspace model layer to set up and run the graph layout algorithm.

This method extracts all models from the workspace and puts them into the combined graph object, LayoutSubgraphs.First() True if all the selected models are groups.

This method repeatedly takes a selected node in the combined graph and uses breadth-first search to find all other nodes in the same subgraph until all selected nodes have been processed.

Gets model list by their GUIDs

Returns the nodes in the graph that have no inputs or have none of their inputs filled

Increment the current paste offset to prevent overlapping pasted elements

Checks whether the given connection is inside the node to code set or outside it. This determines if it should be redrawn(if it is external) or if it should be deleted (if it is internal)

Used during open and workspace changes to set the location of the workspace

Requests that a Node or Note model should be centered.

Used during open and workspace changes to set the zoom of the workspace

Forms new connections from the external nodes to the Node To Code Node, based on the connectors passed as inputs.

Forms new connections from the external nodes to the Node To Code Node, based on the connectors passed as inputs.

TODO(Ben): This method is exposed this way for external codes (e.g. the DragCanvas) to record models before they are modified. This is by no means ideal. The ideal case of course is for ALL codes that end up modifying models to be folded back into WorkspaceViewModel in the form of commands. These commands then internally record those affected models before updating them. We need this method to be gone sooner than later.

This method adds relevant models to the undo recorder.

Removes a node from this workspace. This method does not raise a NodesModified event. (LC notes this is clearly not true)

This function calls the graph layout algorithm methods.

This method pushes changes from the GraphLayout.Graph objects back to the workspace models.

this sets the event on Annotation. This event return the model from the workspace. When a model is ungrouped from a group, that model will be deleted from that group. So, when UNDO execution, cannot get that model from that group, it has to get from the workspace. The below method will set the event on every annotation model, that will return the specific model from workspace.

Returns the model from Workspace

Computes the upstream nodes when workspace is added. when a workspace is added (assuming that all the nodes and its connectors were added successfully) compute the upstream cache for all the frozen nodes.
