NetworkTopologyCalculator
Finds the connected lines that belong to the same network graph.
Input Ports
Network lines
InputLinefeatures must be a topologically noded network with features connecting at line ends only.That is, all features must be split at junctions.
Output Ports
All connected lines are output through theNetworkport.
All non-linear features are output through theInvalidport.
Parameters
Transformer
The default behavior is to use the entire set of features as the group.This option allows you to select attributes that define which groups to form.
Note:How parallel processing works with FME: seeAbout Parallel Processingfor detailed information.
This parameter determines whether or not the transformer should perform the work across parallel processes.If it is enabled, a process will be launched for each group specified by theGroup Byparameter.
Parallel Processing Levels
For example, on a quad-core machine, minimal parallelism will result in two simultaneous FME processes.Extreme parallelism on an 8-core machine would result in 16 simultaneous processes.
You can experiment with this feature and view the information in the Windows Task Manager and the Workbench Log window.
Yes: This transformer will process input groups in order.Changes on the value of theGroup Byparameter on the input stream will trigger batch processing on the currently accumulating group.This will improve overall speed if groups are large/complex, but could cause undesired behavior if input groups are not truly ordered.
No: This is the default behavior.Processing will only occur in this transformer once all input is present.
Parameters
Linear input features that are connected will be assigned the same network ID in the Network ID Attribute.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace.More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers.To access a menu of these options, clickbeside the applicable parameter.For more information, seeTransformer Parameter Menu Options.
