### Properties

### type

{String} Type of spatial filter.

#### The type should be one of

- OpenLayers.Filter.Spatial.BBOX
- OpenLayers.Filter.Spatial.INTERSECTS
- OpenLayers.Filter.Spatial.DWITHIN
- OpenLayers.Filter.Spatial.WITHIN
- OpenLayers.Filter.Spatial.CONTAINS

### property

{String} Name of the context property to compare.

### value

{OpenLayers.Bounds || OpenLayers.Geometry} The bounds or geometry to be used by the filter. Use bounds for BBOX filters and geometry for INTERSECTS or DWITHIN filters.

### distance

{Number} The distance to use in a DWithin spatial filter.

### distanceUnits

{String} The units to use for the distance, e.g. ‘m’.

### Constructor

### OpenLayers.Filter.Spatial

Creates a spatial filter.

#### Parameters

options | {Object} An optional object with properties to set on the filter.

#### Returns

{OpenLayers.Filter.Spatial}

### Functions

### evaluate

> evaluate: function( | feature | )

Evaluates this filter for a specific feature.

#### Parameters

feature | {OpenLayers.Feature.Vector} feature to apply the filter to.

#### Returns

{Boolean} The feature meets filter criteria.

### clone

> clone: function()

Clones this filter.

#### Returns

{OpenLayers.Filter.Spatial} Clone of this filter.

Instances of this class represent bounding boxes.
A Geometry is a description of a geographic object.

> evaluate: function( | feature | )

Evaluates this filter for a specific feature.

> clone: function()

Clones this filter.
This class represents an OGC Filter.
Creates a spatial filter.
Vector features use the OpenLayers.Geometry classes as geometry description.
