/**
|
112 |
* <p>A component that includes a {@link MapContext MapContext} with support for use it as a particular {@link Behavior Behavior}.</p>
|
113 |
*
|
114 |
* <p>A developer can register a set of <code>Behavior</code>, but only one (that can be a composition of several) of them can be active. The active one
|
115 |
* defines the way to work and access with its <code>MapContext</code>'s layers. The active behavior, in combination with the appropriate
|
116 |
* {@link ToolListener ToolListener} will allow user work with a particular <i>tool</i>.</p>
|
117 |
*
|
118 |
* <p>All mouse events produced on this component will be delegated to the current active behavior, the <i>currentMapTool</i>.</p>
|
119 |
*
|
120 |
* <p><b>Drawing process:</b></p>
|
121 |
*
|
122 |
* <p>Uses a double buffer for the drawing process of <code>MapContext</code>'s information.</p>
|
123 |
*
|
124 |
* <p>If the double buffer wasn't created, creates a new one.</p>
|
125 |
*
|
126 |
* <p>Paints the component according the following algorithm:
|
127 |
* <br>
|
128 |
*   If <i>status</i> is <i>UPDATED</i>:<br>
|
129 |
*     If there is a <i>double buffer</i>:<br>
|
130 |
*       If there is a <i>behavior</i> for managing the <code>MapControl</code> instance, delegates
|
131 |
* the drawing process to that behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
132 |
*       Else, repaints the current graphical information quickly calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
133 |
*   Else, (<i>status</i> is <i>OUTDATED</i>, or <i>ONLY_GRAPHICS</i>): executes a quickly repaint of the previous information calling <code>g.drawImage(image,0,0,null)</code>, and creates
|
134 |
* a <i>painting request</i> to delegate the heavy drawing process to the {@link Drawer2 Drawer2}'s worker thread, according the <i>SingleWorketThread</i> pattern, starting a timer to update
|
135 |
* (invoking <code>repaint()</code>) the view every delay of <code>1000 / drawFrameRate</code> ms. during that heavy drawing process, and if its enabled <code>drawAnimationEnabled</code>. The <i>painting request</i> once is being attended, invokes <code>MapContext</code> to
|
136 |
* draw the layers: <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>
|
137 |
* <br>
|
138 |
* <p>Some notes:
|
139 |
* <ul>
|
140 |
* <li>The painting process can be cancelled calling {@link #cancelDrawing() #cancelDrawing()}.</li>
|
141 |
* <li>At last resort, the particular implementation of each layer in a <code>MapControl</code>'s <code>MapContrext</code>
|
142 |
* will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.</li>
|
143 |
* <li>It's possible to force repaint all layers, calling {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
|
144 |
* <li>It's possible repaint only the dirty layers, calling {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>
|
145 |
* <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling {@link #drawGraphics() #drawGraphics()}.</li>
|
146 |
* </ul>
|
147 |
* </p>
|
148 |
*
|
149 |
* <p><b>Tools:</b></p>
|
150 |
*
|
151 |
* <p>A developer can:
|
152 |
* <ul>
|
153 |
* <li>Register each tool as:
|
154 |
* <ul>
|
155 |
* <li>A single behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
156 |
* <li>Or, a compound behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>
|
157 |
* </ul>
|
158 |
* </li>
|
159 |
* <li>Get the current active tool: {@link #getCurrentMapTool() #getCurrentMapTool()}.</li>
|
160 |
* <li>Get the current active tool name: {@link #getCurrentTool() #getCurrentTool()}.</li>
|
161 |

|
162 |
* <li>Get the name of all tools registered: {@link #getMapToolsKeySet() #getMapToolsKeySet()}.</li>
|
163 |
* <li>Get all tools registered, including the name they were registered: {@link #getNamesMapTools() #getNamesMapTools()}.</li>
|
164 |
* <li>Determine if has a tool registered: {@link #hasTool(String) #hasTool(String)}.</li>
|
165 |
* <li>Set as an active tool, one of the registered: {@link #setTool(String) #setTool(String)}.</li>
|
166 |
* <li>Set as active tool, the previous used: {@link #setPrevTool() #setPrevTool()}.</li>
|
167 |
* <li>Set the current tool: {@link #setCurrentMapTool(Behavior) #setCurrentMapTool(Behavior)}.</li>
|
168 |
* <li>Change the draw frame rate: {@link #setDrawFrameRate(int) #setDrawFrameRate(int)} and {@link #applyFrameRate() #applyFrameRate()}.</li>
|
169 |
* <li>Get the draw frame rate: {@link #getDrawFrameRate() #getDrawFrameRate()}.</li>
|
170 |
* <li>Determine if will repaint this component each time timer finishes: {@link #isDrawAnimationEnabled() #isDrawAnimationEnabled()}.</li>
|
171 |
* <li>Change if will repaint this component each time timer finishes: {@link #setDrawAnimationEnabled(boolean) #setDrawAnimationEnabled(boolean)}.</li>
|
172 |
* <li>Get the shared object that determines if a drawing process must be cancelled or can continue: {@link #getCanceldraw() #getCanceldraw()}.</li>
|
173 |
* <li>Get the combined tool: {@link #getCombinedTool() #getCombinedTool()}.</li>

178 |
*
|
179 |
* <p><b>Exception listener:</b></p>
|
180 |
*
|
181 |
* <p> Adding an <code>ExceptionListener</code>, can get notification about any exception produced:
|
182 |
* <ul>
|
183 |
* <li>Attending a <i>painting request</i>.</li>
|
184 |
* <li>Working with the active tool.</li>

192 |

193 |
* <li>Cancel the current drawing process (notifying it also to the inner
