    Member Type Documentation

    enum UtilityTraceFunctionBarrierListModel::UtilityTraceFunctionBarrierRoles

    This enum specifies the custom roles which can be used with UtilityTraceFunctionBarrierListModel::data.

    ConstantValueDescription
    Esri::ArcGISRuntime::UtilityTraceFunctionBarrierListModel::UtilityTraceFunctionBarrierComparisonOperatorQt::UserRole + 1The operator used for the comparison.
    Esri::ArcGISRuntime::UtilityTraceFunctionBarrierListModel::UtilityTraceFunctionBarrierValueQt::UserRole + 2The value to compare against.

    Member Function Documentation

    [override virtual] UtilityTraceFunctionBarrierListModel::~UtilityTraceFunctionBarrierListModel()

    Destructor.

    void UtilityTraceFunctionBarrierListModel::append(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier)

    Appends the utilityTraceFunctionBarrier to the list model.

    [override virtual] Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::at(int index) const

    Returns the UtilityTraceFunctionBarrier at the specified index.

    void UtilityTraceFunctionBarrierListModel::clear()

    Removes all UtilityTraceFunctionBarrier instances from the list model.

    List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

    bool UtilityTraceFunctionBarrierListModel::contains(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier) const

    Returns whether the provided utilityTraceFunctionBarrier is in the list model.

    [override virtual] QVariant UtilityTraceFunctionBarrierListModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const

    Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.

    Returns the data stored under the given role for the UtilityTraceFunctionBarrier referred to by the index.

    • index - The index in the model for which to return data.
    • role - The role for which to return data.

    [signal] void UtilityTraceFunctionBarrierListModel::errorOccurred(const Esri::ArcGISRuntime::Error &error)

    Signal emitted when an error occurs.

    • error - Details about the error.

    Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::first() const

    Returns the first UtilityTraceFunctionBarrier in the list model.

    int UtilityTraceFunctionBarrierListModel::indexOf(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier) const

    Returns the index of the provided utilityTraceFunctionBarrier in the list model.

    void UtilityTraceFunctionBarrierListModel::insert(int index, Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier)

    Inserts a utilityTraceFunctionBarrier at a specified index in the list model.

    bool UtilityTraceFunctionBarrierListModel::isEmpty() const

    Returns true if this list model is empty.

    [signal, since Esri::ArcGISRuntime 100.15] void UtilityTraceFunctionBarrierListModel::itemAdded(int index)

    Signal emitted when an item is added to the list.

    index is the index of the added item.

    This function was introduced in Esri::ArcGISRuntime 100.15.

    [signal, since Esri::ArcGISRuntime 100.15] void UtilityTraceFunctionBarrierListModel::itemRemoved(int index)

    Signal emitted when an item is removed from the list.

    index is the index of the removed item.

    This function was introduced in Esri::ArcGISRuntime 100.15.

    Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::last() const

    Returns the last UtilityTraceFunctionBarrier in the list model.

    void UtilityTraceFunctionBarrierListModel::move(int from, int to)

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

    void UtilityTraceFunctionBarrierListModel::removeAt(int index)

    Removes a UtilityTraceFunctionBarrier at the specified index in the list model.

    List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

    void UtilityTraceFunctionBarrierListModel::removeOne(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier)

    Removes the specified utilityTraceFunctionBarrier from the list model.

    List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.

    [override virtual] int UtilityTraceFunctionBarrierListModel::size() const

    Returns the number of trace function barriers in the model.
