Constructor

# new VectorLayer(opts)

Initialization object

Parameters:

Name	Type	Attributes	Default	Description
`opts`	`object`			WFS layer options
`name`	`string`	<optional>		Layer name
`order`	`number`	<optional>		The order for layer rendering. At rendering time, the layers will be ordered, first by order and then by position. When undefined, a order of 0 is assumed for layers that are added to the map's layers collection.
`visible`	`boolean`	<optional>	true	Visibility
`opacity`	`number`	<optional>	1	Opacity (0, 1).
`features`	`Array.<Feature>`	<optional>		Feature list, the geometry of the features must be on geographic coordinates
`style`	`Array.<Style>`	<optional>		Array of custom styles, to modify how to render the vector data. Also you can pass a function that return a style, this function it's called for each feature and receive feature an resolution in the parameters
`url`	`string`	<optional>		Setting this option instructs the source to load features using an XHR loader. Use a string a one-off download of all features from the given URL. Default format is GeoJSON. When default XHR feature loader is provided, the features will be transformed from the data projection to the view projection during parsing. The default projection is EPSG:4326. Note that if a source contains non-feature data, such as a GeoJSON geometry

Methods

# addFeatures(features)

Add new features to the vector layer, the geometry of the features must be on geographic coordinates

Parameters:

Name	Type	Description
`features`	`array.<Feature>`

# clear()

Remove all features

# getFeatures() → {array.<Feature>}

Return the current feature list of the layer

Returns:

Type: array.<Feature>

# getMaxZoom() → {number}

Gets the maximum zoom level of the layer.

Overrides:

InternalVectorLayer#getMaxZoom

Returns:

The maximum zoom level of the layer.

Type: number

# getMinZoom() → {number}

Gets the minimum zoom level of the layer.

Overrides:

InternalVectorLayer#getMinZoom

Returns:

The minimum zoom level of the layer.

Type: number

# getOpacity() → {number}

Gets the opacity of the layer (between 0 and 1).

Overrides:

InternalVectorLayer#getOpacity

Returns:

The opacity of the layer.

Type: number

# getVisible() → {boolean}

Gets the visibility of the layer (true or false).

Overrides:

InternalVectorLayer#getVisible

Returns:

The visibility of the layer.

Type: boolean

# removeFeature(feature)

Remove a single feature from the source. If you want to remove all features at once, use the #clear() method instead.

Parameters:

Name	Type	Description
`feature`	`Feature`	Feature to remove

# setMaxZoom(maxZoom)

Sets the maximum zoom (exclusive) at which the layer is visible. Note that the zoom levels for layer visibility are based on the view zoom level, which may be different from a tile source zoom level.

Parameters:

Name	Type	Description
`maxZoom`	`number`	The maximum zoom of the layer.

Overrides:

InternalVectorLayer#setMaxZoom

# setMinZoom(minZoom)

Sets the minimum zoom (inclusive) at which the layer is visible. Note that the zoom levels for layer visibility are based on the view zoom level, which may be different from a tile source zoom level.

Parameters:

Name	Type	Description
`minZoom`	`number`	The minimum zoom of the layer.

Overrides:

InternalVectorLayer#setMinZoom

# setOpacity(opacity)

Sets the opacity of the layer, allowed values range from 0 to 1.

Parameters:

Name	Type	Description
`opacity`	`number`	The opacity of the layer.

Overrides:

InternalVectorLayer#setOpacity

# setVisible(visible)

Sets the visibility of the layer (true or false).

Parameters:

Name	Type	Description
`visible`	`boolean`	The visibility of the layer.

Overrides:

InternalVectorLayer#setVisible
