Flow properties

You can control a variety of flow properties with scripting. To reference flow properties, you must set the execution method to use scripts:

stream = modeler.script.stream()
stream.setPropertyValue("execute_method", "Script")
Copy to clipboardCopied to clipboard

stream = modeler.script.stream()
annotation = stream.getPropertyValue("annotation")

annotation = annotation + "\n\nThis flow is called \"" + stream.getLabel() + "\" and
 contains the following nodes:\n"

for node in stream.iterator():
    annotation = annotation + "\n" + node.getTypeName() + " node called \"" + node.getLabel()
 + "\""

stream.setPropertyValue("annotation", annotation)

The previous example uses the node property to create a list of all nodes in the flow and write that list in the flow annotations. The annotation produced looks like this:

This flow is called "druglearn" and contains the following nodes:

type node called "Define Types"
derive node called "Na_to_K"
variablefile node called "DRUG1n"
neuralnetwork node called "Drug"
c50 node called "Drug"
filter node called "Discard Fields"
