* <p>All layers in <i>libFMap</i> can be in a set of <i>states</i>, that their combination represent the <i>status</i> of a layer.</p>
|
66 |
*
|
67 |
* <p><code>FLayerStatus</code> class supports the common status for all kind of {@link FLyrDefault FLyrDefault} layers.</p>
|
68 |
*
|
69 |
* <p>This means that not necessarily all layers can stay in all possible status, it depends on its particular
|
70 |
* nature.</p>
|
71 |
*
|
72 |
* <p>Layer status states defined in <code>FLayerStatus</code> are:
|
73 |
* <ul>
|
74 |
* <li><i><b>Available</b></i>: the layer is available if the source of its data is on-line.</li>
|
75 |
* <li><i><b>Visible</b></i>: one layer is visible if it's selected its <i>check box</i> associated in TOC. This implies that
|
76 |
* layer will be called to be painted unless the necessary data would be unavailable; this situation is more frequent with layers of
|
77 |
* remote services.</li>
|
78 |
* <li><i><b>Active</b></i>: is active if it's selected at the TOC.</li>
|
79 |
* <li><i><b>Dirty</b></i>: is dirty if needs to be refreshed.</li>
|
80 |
* <li><i><b>In TOC</b></i>: if it's being listed in a TOC GUI.</li>
|
81 |
* <li><i><b>Editing</b></i>: if the layer it's being edited now.</li>
|
82 |
* <li><i><b>Writable</b></i>: if can be modified and saved the changes.</li>
|
83 |
* <li><i><b>Cache drawn layers</b></i>: if stores previous draws. This is useful to accelerate the draw of the layer.</li>
|
84 |
* <li><i><b>Driver loaded</b></i>: if driver for managing the layer has been loaded successfully.</li>
