Detailed Description
Modifying this model (adding, removing, moving) will update the VectorMarkerSymbolLayer.
The model returns data for the following roles:
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.
|
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.
|
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(VectorMarkerSymbolElement vectorMarkerSymbolElement) |
Appends a vectorMarkerSymbolElement to the symbol list model.
void clear() |
Removes all vector marker symbol elements from the list model.
bool contains(VectorMarkerSymbolElement 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:
- element Current vector marker symbol element.
- index Current index in array.
- array Reference to VectorMarkerSymbolElementListModel.
Returns undefined if no error occurred, and an error message otherwise.
const error = VectorMarkerSymbolElementListModel.forEach(function(element, index, array) { ... }); if (error) { console.error(error.message); }
VectorMarkerSymbolElement get(int index) |
Returns the VectorMarkerSymbolElement at the specified index.
|
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(int index, VectorMarkerSymbolElement vectorMarkerSymbolElement) |
Inserts a vectorMarkerSymbolElement at a specified index in the list.
void move(int from, int to) |
Moves one vector marker symbol element 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.
|
Removes the specified vector marker symbol element (vectorMarkerSymbolElement) from the list model.
This method was introduced in Esri::ArcGISRuntime 100.5..
