  • void append(vectorMarkerSymbolElement)
  • void clear()
  • bool contains(vectorMarkerSymbolElement)
  • void forEach(callback)
  • VectorMarkerSymbolElement get(index)
  • int indexOf(vectorMarkerSymbolElement)

Detailed Description

Modifying this model (adding, removing, moving) will update the VectorMarkerSymbolLayer.

The model returns data for the following roles:

RoleTypeDescription
geometryGeometryThe geometry.
symbolSymbolThe symbol.

Property Documentation

count : int

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


error : Error

Returns the Error object (read-only).


Signal Documentation

countChanged()

Emitted when the count property of the model changes.

Note: The corresponding handler is onCountChanged.


errorChanged()

Emitted when the error property changes, which can indicate that an error occurred.

Note: The corresponding handler is onErrorChanged.


vectorMarkerSymbolElementAdded(index)

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

Note: The corresponding handler is onVectorMarkerSymbolElementAdded.


vectorMarkerSymbolElementRemoved(index)

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

Note: The corresponding handler is onVectorMarkerSymbolElementRemoved.


Method Documentation

void append(vectorMarkerSymbolElement)

Appends a vectorMarkerSymbolElement to the symbol list model.


void clear()

Removes all vector marker symbol elements from the list model.


bool contains(vectorMarkerSymbolElement)

Returns true if the list model contains the specified vectorMarkerSymbolElement.


void forEach(callback)

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

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

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

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

Returns the VectorMarkerSymbolElement at the specified index.


int indexOf(vectorMarkerSymbolElement)

Returns the index of a specific vector marker symbol element (vectorMarkerSymbolElement) from the list model.

This method was introduced in Esri::ArcGISRuntime 100.5..


void insert(index, VectorMarkerSymbolElement vectorMarkerSymbolElement)

Inserts a vectorMarkerSymbolElement at a specified index in the list.


void move(from, int to)

Moves one vector marker symbol element from an index in the list model to a different index.


void remove(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(vectorMarkerSymbolElement)

Removes the specified vector marker symbol element (vectorMarkerSymbolElement) from the list model.

This method was introduced in Esri::ArcGISRuntime 100.5..
