    Detailed Description

    Note: You cannot declare or create a component of this type in QML code.

    The model returns data for the following roles:

    RoleTypeDescription
    comparisonOperatorUtilityAttributeComparisonOperatorThe operator that is applied when executing the trace
    networkAttributeUtilityNetworkAttributeTThe UtilityNetworkAttribute to propagate further along the trace
    propagatorFunctionTypeUtilityTraceFunctionFunctionTypeThe function type that is applied to the UtilityNetworkAttribute
    substitutionNetworkAttributeUtilityNetworkAttributeThe UtilityNetworkAttribute that maps each bit in another bitset
    valueQVariantThe value that is compared against the propagated value when executing the trace

    See also UtilityTraceFunction.

    Property Documentation

    [read-only] count : int

    Returns the number of objects in the model (read-only).


    Signal Documentation

    countChanged()

    Emitted when the count property of the model changes.

    Note: The corresponding handler is onCountChanged.


    [since Esri.ArcGISRuntime 100.15] itemAdded(int index)

    Emitted when an item is added to the list model at the index specified in the parameter.

    Note: The corresponding handler is onItemAdded.

    This signal was introduced in Esri.ArcGISRuntime 100.15.


    [since Esri.ArcGISRuntime 100.15] itemRemoved(int index)

    Emitted when an item is removed from the list model at the index specified in the parameter.

    Note: The corresponding handler is onItemRemoved.

    This signal was introduced in Esri.ArcGISRuntime 100.15.


    Method Documentation

    void append(UtilityTraceFunction utilityTraceFunction)

    Appends a utilityTraceFunction to the UtilityTraceFunction list model.


    void clear()

    Removes all utility propagators from the list model.


    bool contains(UtilityTraceFunction utilityTraceFunction)

    Returns true if the list model contains the specified utilityTraceFunction.


    error forEach(callback)

    Receives a callback function to execute for each utility propagator in the model.

    The callback function can take from 0 to 3 optional arguments, in order:

    Returns undefined if no error occurred, and an error message otherwise.

    const error = UtilityTraceFunctionListModel.forEach(function(element, index, array) {
        ...
    });
    if (error) {
        console.error(error.message);
    }

    UtilityTraceFunction get(int index)

    Returns the utility propagator at the specified index.


    int indexOf(UtilityTraceFunction utilityTraceFunction)

    Returns the index of a specific utilityTraceFunction from the list model.


    void insert(int index, UtilityTraceFunction utilityTraceFunction)

    Inserts a utilityTraceFunction at a specified index in the list.


    void move(int from, int to)

    Moves one utility propagator from an index in the list model to a different index.


    void remove(int index, int count = 1)

    Removes one or more objects starting at the specified index.

    • index Index of first object to remove
    • count Number of objects to remove. This parameter defaults to 1

    void removeOne(UtilityTraceFunction utilityTraceFunction)

    Removes the specified utilityTraceFunction from the list model.
