Inheritance	CompositeSymbol Symbol flash.events.EventDispatcher

Used to draw multiple symbols on a single graphic. The symbols can be a combination of point, line and fill symbols. For example, on polyline and polygon features a SimpleMarkerSymbol can be used for each node. Uses the ArrayCollection of the symbol objects to draw the respective symbols.

Property detail

symbols

property

symbols:Object [read-write]

Used to draw multiple symbols on point, line or polygon features in a GraphicsLayer. This property lets you use either an Array, an ArrayCollection, or a single Symbol. If you set the symbols property to an Array, it will be converted to an ArrayCollection. If you set the property to an ArrayCollection, it will be used directly. If you set the property to a single Symbol, it will be wrapped in a new ArrayCollection.

The default value is an empty ArrayCollection.

This property can be used as the source for data binding.

Implementation
public function get symbols():Object
public function set symbols(value:Object):void
