Detailed Description

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

The model returns data for the following roles:

Role	Type	Description
comparisonOperator	UtilityAttributeComparisonOperator	The operator that is applied when executing the trace
networkAttribute	UtilityNetworkAttribute	TThe UtilityNetworkAttribute to propagate further along the trace
propagatorFunctionType	UtilityTraceFunctionFunctionType	The function type that is applied to the UtilityNetworkAttribute
substitutionNetworkAttribute	UtilityNetworkAttribute	The UtilityNetworkAttribute that maps each bit in another bitset
value	QVariant	The value that is compared against the propagated value when executing the trace

See also UtilityTraceFunction.

Property Documentation

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.

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.

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:

element Current utility propagator
index Current index in array
array Reference to UtilityTraceFunctionListModel

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.
