geometryToLayer

@JsMethod
public static ILayer geometryToLayer(com.google.gwt.core.client.JavaScriptObject featureData,
                                                Function pointToLayer)

Creates a layer from a given GeoJSON feature.

coordsToLatlng

@JsMethod
public static LatLng coordsToLatlng(com.google.gwt.core.client.JsArray<com.google.gwt.core.client.JavaScriptObject> coords,
                                               java.lang.Boolean reverse)

Creates a LatLng object from an array of 2 numbers (latitude, longitude) used in GeoJSON for points. If reverse is set to true, the numbers will be interpreted as (longitude, latitude).

Parameters:

coords - the coordinates

reverse - the reverse

Returns:

the lat lng

coordsToLatlngs

@JsMethod
public static com.google.gwt.core.client.JsArray<com.google.gwt.core.client.JavaScriptObject> coordsToLatlngs(com.google.gwt.core.client.JsArray<com.google.gwt.core.client.JavaScriptObject> coords,
                                                                                                                         java.lang.Number levelsDeep,
                                                                                                                         java.lang.Boolean reverse)

Creates a multidimensional array of LatLng objects from a GeoJSON coordinates array. levelsDeep specifies the nesting level (0 is for an array of points, 1 for an array of arrays of points, etc., 0 by default). If reverse is set to true, the numbers will be interpreted as (longitude, latitude).

Parameters:

coords - the coordinates

levelsDeep - specifies the nesting level

reverse - the reverse

Returns:

js array of coordinates
