/** |
|
80 |
* This class provides various pieces of information relevant to a |
|
81 |
* particular drawing surface. The information obtained from this |
|
82 |
* object describes the pixels of a particular instance of a drawing |
|
83 |
* surface and can only be shared among the various graphics objects |
|
84 |
* that target the same BufferedImage or the same screen Component. |
|
85 |
* <p> |
|
86 |
* Each SurfaceData object holds a StateTrackableDelegate object |
|
87 |
* which tracks both changes to the content of the pixels of this |
|
88 |
* surface and changes to the overall state of the pixels - such |
|
89 |
* as becoming invalid or losing the surface. The delegate is |
|
90 |
* marked "dirty" whenever the setSurfaceLost() or invalidate() |
|
91 |
* methods are called and should also be marked "dirty" by the |
|
92 |
* rendering pipelines whenever they modify the pixels of this |
|
93 |
* SurfaceData. |
|
94 |
* <p> |
|
95 |
* If you get a StateTracker from a SurfaceData and it reports |
|
96 |
* that it is still "current", then you can trust that the pixels |
|
97 |
* have not changed and that the SurfaceData is still valid and |
|
98 |
* has not lost its underlying storage (surfaceLost) since you |
|
99 |
* retrieved the tracker. |

|
147 |
* This key is a "tag" used to identify which cached copies |
|
148 |
* are compatible with this destination SurfaceData. |
|
149 |
* The getSourceSurfaceData() method uses this key to manage |
|
150 |
* cached copies of a source image as described below. |
|
151 |
* <p> |
|
152 |
* The Object used as this key should be as unique as it needs |

153 |
* to be to ensure that multiple acceleratible destinations can |

156 |
* cached copy. |

* <p> |
|
158 |
* Many acceleratable SurfaceData objects can use their own |

159 |
* GraphicsConfiguration as their proxy key as the GC object will |
|
160 |
* typically be unique to a given screen and pixel format, but |
|
161 |
* other rendering destinations may have more or less stringent |
|
162 |
* sharing requirements. For instance, X11 pixmaps can be |
|
163 |
* shared on a given screen by any GraphicsConfiguration that |
|
164 |
* has the same depth and SurfaceType. Multiple such GCs with |
|
165 |
* the same depth and SurfaceType can exist per screen so storing |
|
166 |
* a different cached proxy for each would be a waste. One can |
|
167 |
* imagine platforms where a single cached copy can be created |
|
168 |
* and shared across all screens and pixel formats - such |
|
169 |
* implementations could use a single heavily shared key Object. |

197 |
* <li> Image pipeline asks destSD to find an appropriate |
|
198 |
* srcSD for a given source Image object. |

* <li> destSD gets the SurfaceManager of the source Image |
|
200 |
* and first retrieves the default SD from it using |
|
201 |
* getPrimarySurfaceData() |
|
202 |
* <li> destSD uses its "blit proxy key" (if set) to look for |
|
203 |
* some cached data stored in the source SurfaceManager |
|
204 |
* <li> If the cached data is null then makeProxyFor() is used |
|
205 |
* to create some cached data which is stored back in the |
|
206 |
* source SurfaceManager under the same key for future uses. |
|
207 |
* <li> The cached data will be a SurfaceDataProxy object. |
|
208 |
* <li> The SurfaceDataProxy object is then consulted to |
|
209 |
* return a replacement SurfaceData object (typically |
|
210 |
* a cached copy if appropriate, or the original if not). |
|
211 |
