Propiedades

Propiedad	Explicación	Tipo de datos
networkAttributeName (Sólo lectura)	The name of the network attribute used to filter the propagators condition.	String
networkAttributeOperator (Sólo lectura)	The type of operator used for the propagation—for example, is equal to or is less than.	String
propagatedAttributeName (Sólo lectura)	The name of the field that is used to store the calculated propagated values. The field type should match that of the field used for the networkAttributeName property.	String
substitutionAttributeName (Sólo lectura)	The network attribute used for substitution.	String
tracePropagatorFunctionType (Sólo lectura)	The type of function used for the function barrier—for example, propagated BitwiseAnd, Min, or Max.	String
value (Sólo lectura)	The specific value of the network attribute or category used for the propagation.	Integer

Utility network propagator properties example (stand-alone script)

This stand-alone Python script prints a report of utility network properties.

# Import required modules

# For each domain network in the utility network
for dom in domnets:
