Detailed Description

This class is the model for the PipelineLine browser tree view.

The pqPipelineModel class is used to represent the pipeline graph as a tree.

pqServerManagerModel models the vtkSMProxyManager for the GUI. The vtkSMProxyManager maintains all proxies and hence it is difficult to detect/trasvers pipelines etc etc. The pqServerManagerModel provides a simplified view of the Server Manager. This class takes that simplified "model" and transforms it into hierarchical tables which can be represented by the Tree View.

The top of the hierarchy is the server objects. Each connected server is added to the root node. An object with no inputs is added as a child of its server. The outputs of an object are added as its children. Objects with multiple inputs present a problem.

Instead of repeating information in the tree, the object with multiple inputs is moved to the server. All its outputs are treated normally and added as children. In place of the object with more than one input, a link object is placed in the child list of the input objects. The link item represents a connection instead of a pipeline object.
