Static Public Member Functions | |
| static | addFont (string filename, TextFont font) |
| Adds the indicated already-loaded font to the pool. | |
| static int | garbageCollect () |
| Releases only those fonts in the pool that have a reference count of exactly 1; i.e. | |
| static bool | hasFont (string filename) |
| Returns true if the font has ever been loaded, false otherwise. | |
| static | listContents (ostream out) |
| Lists the contents of the font pool to the indicated output stream. | |
| static TextFont | loadFont (string filename) |
| Loads the given filename up into a font, if it has not already been loaded, and returns the new font. | |
| static | releaseAllFonts () |
| Releases all fonts in the pool and restores the pool to the empty state. | |
| static | releaseFont (string filename) |
| Removes the indicated font from the pool, indicating it will never be loaded again; the font may then be freed. | |
| static bool | verifyFont (string filename) |
| Loads the given filename up into a font, if it has not already been loaded, and returns true to indicate success, or false to indicate failure. | |
| static | write (ostream out) |
| Lists the contents of the font pool to the indicated output stream. | |
This is the preferred interface for loading fonts for the TextNode system.
It is similar to ModelPool and TexturePool in that it unifies references to the same filename.
| static addFont | ( | string | filename, |
| TextFont | font | ||
| ) | [static] |
Adds the indicated already-loaded font to the pool.
The font will always replace any previously-loaded font in the pool that had the same filename.
| static int garbageCollect | ( | ) | [static] |
Releases only those fonts in the pool that have a reference count of exactly 1; i.e.
only those fonts that are not being used outside of the pool. Returns the number of fonts released.
| static bool hasFont | ( | string | filename | ) | [static] |
Returns true if the font has ever been loaded, false otherwise.
| static listContents | ( | ostream | out | ) | [static] |
Lists the contents of the font pool to the indicated output stream.
| static TextFont loadFont | ( | string | filename | ) | [static] |
Loads the given filename up into a font, if it has not already been loaded, and returns the new font.
If a font with the same filename was previously loaded, returns that one instead. If the font file cannot be found, returns NULL.
| static releaseAllFonts | ( | ) | [static] |
Releases all fonts in the pool and restores the pool to the empty state.
| static releaseFont | ( | string | filename | ) | [static] |
Removes the indicated font from the pool, indicating it will never be loaded again; the font may then be freed.
If this function is never called, a reference count will be maintained on every font every loaded, and fonts will never be freed.
| static bool verifyFont | ( | string | filename | ) | [static] |
Loads the given filename up into a font, if it has not already been loaded, and returns true to indicate success, or false to indicate failure.
If this returns true, it is guaranteed that a subsequent call to load_font() with the same font name will return a valid Font pointer.
| static write | ( | ostream | out | ) | [static] |
Lists the contents of the font pool to the indicated output stream.
