Returns a new builder for creating a MbTilesFeatureLayer.

Returns:

a new builder for creating a MbTilesFeatureLayer.

asBuilder

@NotNull
public MbTilesFeatureLayer.Builder asBuilder()

Returns a new builder based on this layer instance.

You can use this builder, for example, to create a copy of this layer.

Note that observers will not be transferred to a new layer.

Returns:

a new builder based on this layer instance.

getModel

@NotNull
public IFeatureTileModel getModel()

Returns the layer's model, which provides the feature tiles to present.

Returns:

the layer's model, which provides the feature tiles to present.

isLabeled

public boolean isLabeled()

Returns whether this layer displays labels.

Returns:

whether this layer displays labels.

setLabeled

public void setLabeled(boolean labeled)

Sets whether this layer displays labels.

Parameters:

labeled - true to enable labels.

setStyle

public void setStyle(@NotNull
 String path)
              throws IOException

Sets the style of the layer.

When setting a new style, a LayerEvent is delivered to the observers with the property name MbTilesFeatureLayer#propertyStyle.

Parameters:

path - the path to a style file. Can be a URL or a file path to a JSON file.

Throws:

IOException - If decoding the style fails.
