Detailed Description
A UtilityTraceFunctionBarrier performs a comparison expression between the current results of a UtilityTraceFunction and a given value. A UtilityTraceFunction references a UtilityNetworkAttribute and a calculation that is applied to it (Min, Max, Count, and so on). Once the comparison evaluates as true, network traversal stops.
Member Function Documentation
UtilityTraceFunctionBarrier::UtilityTraceFunctionBarrier (Esri::ArcGISRuntime::UtilityTraceFunction *traceFunction , Esri::ArcGISRuntime::UtilityAttributeComparisonOperator comparisonOperator , const QVariant &value, QObject *parent = nullptr)
Creates a barrier that stops tracing when a UtilityTraceFunction compared to a value evaluates to true.
- traceFunction - The calculation to perform.
- comparisonOperator - The operator used for the comparison.
- value - The value to compare against. The type of this numeric value depends on the UtilityNetworkAttributeDataType of the UtilityNetworkAttribute.
- parent - an optional parent QObject.
[override virtual] UtilityTraceFunctionBarrier::~UtilityTraceFunctionBarrier ()
