FLayerStatus

java.lang.Object
- org.gvsig.fmap.mapcontext.layers.FLayerStatus

All Implemented Interfaces:

IFLayerStatus, Persistent
```
public class FLayerStatus
extends java.lang.Object
implements IFLayerStatus
```
All layers in libFMap can be in a set of states, that their combination represent the status of a layer.

FLayerStatus class supports the common status for all kind of FLyrDefault layers.

This means that not necessarily all layers can stay in all possible status, it depends on its particular nature.

Layer status states defined in FLayerStatus are:
- Available: the layer is available if the source of its data is on-line.
- Visible: one layer is visible if it's selected its check box associated in TOC. This implies that layer will be called to be painted unless the necessary data would be unavailable; this situation is more frequent with layers of remote services.
- Active: is active if it's selected at the TOC.
- Dirty: is dirty if needs to be refreshed.
- In TOC: if it's being listed in a TOC GUI.
- Editing: if the layer it's being edited now.
- Writable: if can be modified and saved the changes.
- Cache drawn layers: if stores previous draws. This is useful to accelerate the draw of the layer.
- Driver loaded: if driver for managing the layer has been loaded successfully.

  - inTOC
```
public boolean inTOC
```
    The layer is in TOC if it's being listed in a TOC GUI.
  - editing
```
public boolean editing

```
public boolean writable
```
    This parameter reports if the layer can be modified and saved the changes.
