OpenLayers. Feature. Vector

Vector features use the OpenLayers.Geometry classes as geometry description. They have an ‘attributes’ property, which is the data object, and a ‘style’ property, the default values of which are defined in the OpenLayers.Feature.Vector.style objects.

Functions

OpenLayers. Feature. Vector

Create a vector feature.

Parameters

geometry	{OpenLayers.Geometry}
data	{Object}
style	{Object}

destroy

destroy: function()

nullify references to prevent circular references and memory leaks

clone

clone: function ( obj )

Returns

OpenLayers.Feature An exact clone of this OpenLayers.Feature

atPoint

atPoint: function( lonlat,
toleranceLon,
toleranceLat )

Determins whether the feature intersects with the specified location.

Parameters

lonlat	{OpenLayers.LonLat}
toleranceLon	{float} Optional tolerance in Geometric Coords

Sets the new state

Parameters

state

{String}

Constants

OpenLayers. Feature. Vector. style

OpenLayers features can have a number of style attributes. The ‘default’ style will typically be used if no other style is specified.

Default style properties

fillColor: “#ee9900”,
fillOpacity: 0.4,
hoverFillColor: “white”,
hoverFillOpacity: 0.8,
strokeColor: “#ee9900”,
strokeOpacity: 1,
strokeWidth: 1,
strokeLinecap: “round”,
hoverStrokeColor: “red”,
hoverStrokeOpacity: 1,
hoverStrokeWidth: 0.2,
pointRadius: 6,
hoverPointRadius: 1,
hoverPointUnit: “%”,
pointerEvents: “visiblePainted”

A Geometry is a description of a geographic object.

destroy: function()

nullify references to prevent circular references and memory leaks

clone: function ( obj )

OpenLayers.Feature An exact clone of this OpenLayers.Feature

Features are combinations of geography and attributes.

atPoint: function( lonlat,
toleranceLon,
toleranceLat )

Determins whether the feature intersects with the specified location.

toState: function( state )

Sets the new state

OpenLayers features can have a number of style attributes.

This class represents a longitude and latitude pair
