Detailed Description
Modifying this model (adding, removing, moving) will update the VectorMarkerSymbolLayer.
The model returns data for the following roles:
Property Documentation
error : Error |
Returns the Error object (read-only).
Signal Documentation
Emitted when the count property of the model changes.
Note: The corresponding handler is onCountChanged
.
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.
bool contains(VectorMarkerSymbolElement vectorMarkerSymbolElement) |
Returns true
if the list model contains the specified vectorMarkerSymbolElement.
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.
int indexOf(VectorMarkerSymbolElement 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(int index, VectorMarkerSymbolElement vectorMarkerSymbolElement) |
Inserts a vectorMarkerSymbolElement at a specified index in the list.
Moves one vector marker symbol element from an index in the list model to a different index.
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 vectorMarkerSymbolElement) |
Removes the specified vector marker symbol element (vectorMarkerSymbolElement) from the list model.
This method was introduced in Esri::ArcGISRuntime 100.5..
