Class: Vector

SuperMap.Feature.Vector

The vector feature class has Geometry property to store the geometric information, attributes property to store the non-geometric information, and also includes the style property to define the style of the vector element, in which, the default style is defined in the SuperMap.Feature.Vector.style.

new SuperMap.Feature.Vector(geometry, attributes, style)

Vector.js, line 7
Name Type Description
geometry SuperMap.Geometry

geometry shape of features.
attributes Object optional

This object holds arbitrary, serializable properties that describe the feature.
style Object optional

A selectable style object.
Example
var geometry = new SuperMap.Geometry.Point(-115,10);
 var style = {
     strokeColor:"#339933",
     strokeOpacity:1,
     strokeWidth:3,
     pointRadius:6
 }
 var pointFeature = new SuperMap.Feature.Vector(geometry,null,style);
 vectorLayer.addFeatures(pointFeature);

Members

attributesObject

This object holds arbitrary, serializable properties that describe the feature.

boundsSuperMap.Bounds

The box bounding that feature's geometry, that property can be set by an <SuperMap.Format> object when deserializing the feature, so in most cases it represents an information set by the server.

dataObject

The data object.

fidstring

fid

geometrySuperMap.Geometry

A Geometry is a description of a geographic object.

idstring

The feature id.

layerSuperMap.Layer

The layer.

Deprecated
  • Yes

lonlatSuperMap.LonLat

The longitude and latitude.

statestring

state

styleObject

The style attribute of features. The style of feature returned by map query. In 8C it has changed to null.

urlstring

If this property is set it will be taken into account by SuperMap.HTTP when updating or deleting the feature.

Methods

clone(){SuperMap.Feature.Vector}

Vector.js, line 187

isUnicode boolean false optional

This property should combine with lable property. If it is true, label can use unicode. e.g., the unicode of "a" is 61, so the label property can be a, where &# is prefix, x is hexadecimal; if it is false, the label will output a, the display a. The default is false.
