public Layer()
```
- Method Detail
  - addKMLToMap
```
protected void addKMLToMap()
```
    Adds the KML data to the map
  - addGeoJsonToMap
```
protected void addGeoJsonToMap()
```
    Adds GeoJson data to the map
  - addLayerToMap
```
public abstract void addLayerToMap()
```
  - removeLayerFromMap
```
public void removeLayerFromMap()
```
    Removes all the data from the map and clears all the stored placemarks
  - setOnFeatureClickListener
```
public void setOnFeatureClickListener(Layer.OnFeatureClickListener listener)
```
    Sets a single click listener for the entire GoogleMap object, that will be called with the corresponding Feature object when an object on the map (Polygon, Marker, Polyline) is clicked.
    If getFeature() returns null this means that either the object is inside a KMLContainer, or the object is a MultiPolygon, MultiLineString or MultiPoint and must be handled differently.
    
    Parameters:
    
    listener - Listener providing the onFeatureClick method to call.
  - storeRenderer
```
protected void storeRenderer(Renderer renderer)
```
    Stores a new Renderer object into mRenderer
    
    Parameters:
    
    renderer - the new Renderer object that belongs to this Layer
  - getFeatures
```
public java.lang.Iterable<? extends Feature> getFeatures()
```
    Gets an iterable of all Feature elements that have been added to the layer
    
    Returns:
    
    iterable of Feature elements
  - getFeature
```
public Feature getFeature(java.lang.Object mapObject)
```
    Retrieves a corresponding Feature instance for the given Object Allows maps with multiple layers to determine which layer the Object belongs to.
    
    Parameters:
    
    mapObject - Object
    
    Returns:
    
    Feature for the given object
  - getContainerFeature
```

```
  - hasFeatures
```
protected boolean hasFeatures()
```
    Checks if there are any features currently on the layer
    
    Returns:
    
    true if there are features on the layer, false otherwise
  - hasContainers
```
protected boolean hasContainers()
```

    Returns:
    
    true if there is at least 1 container within the KmlLayer, false otherwise
  - getContainers
```
protected java.lang.Iterable<KmlContainer> getContainers()
```
    Gets an iterable of KmlContainerInterface objects
    
    Returns:
    
    iterable of KmlContainerInterface objects

```
    Gets an iterable of KmlGroundOverlay objects
    
    Returns:
    
    iterable of KmlGroundOverlay objects
  - getMap
```
public GoogleMap getMap()
```
    Gets the map on which the layer is rendered
    
    Returns:
    
    map on which the layer is rendered
  - setMap

  - isLayerOnMap
```
public boolean isLayerOnMap()
```
    Checks if the current layer has been added to the map
    
    Returns:
    
    true if the layer is on the map, false otherwise
  - addFeature
```
protected void addFeature(Feature feature)
```
    Adds a provided feature to the map
    
    Parameters:
    
    feature - feature to add to map
