Static Public Member Functions | |
static | addModel (Filename const filename, ModelRoot model) |
Adds the indicated already-loaded model to the pool. | |
static | addModel (ModelRoot model) |
Adds the indicated already-loaded model to the pool. | |
static int | garbageCollect () |
Releases only those models in the pool that have a reference count of exactly 1; i.e. | |
static bool | hasModel (Filename const filename) |
Returns true if the model has ever been loaded, false otherwise. | |
static | listContents () |
Lists the contents of the model pool to cout. | |
static | listContents (ostream out) |
Lists the contents of the model pool to the indicated output stream. | |
static ModelRoot | loadModel (Filename const filename, LoaderOptions const options) |
Loads the given filename up as a model, if it has not already been loaded, and returns the new model. | |
static ModelRoot | loadModel (Filename const filename) |
Loads the given filename up as a model, if it has not already been loaded, and returns the new model. | |
static | releaseAllModels () |
Releases all models in the pool and restores the pool to the empty state. | |
static | releaseModel (Filename const filename) |
Removes the indicated model from the pool, indicating it will never be loaded again; the model may then be freed. | |
static | releaseModel (ModelRoot model) |
Removes the indicated model from the pool, indicating it will never be loaded again; the model may then be freed. | |
static bool | verifyModel (Filename const filename) |
Loads the given filename up as a model, 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 model pool to the indicated output stream. |
This class unifies all references to the same filename, so that multiple attempts to load the same model will return the same pointer.
Note that the default behavior is thus to make instances: use with caution. Use the copy_subgraph() method on Node (or use NodePath::copy_to) to make modifiable copies of the node.
Unlike TexturePool, this class does not automatically resolve the model filenames before loading, so a relative path and an absolute path to the same model will appear to be different filenames.
However, see the Loader class, which is now the preferred interface for loading models. The Loader class can resolve filenames, supports threaded loading, and can automatically consult the ModelPool, according to the supplied LoaderOptions.
Adds the indicated already-loaded model to the pool.
The model will always replace any previously-loaded model in the pool that had the same filename.
This two-parameter version of this method is deprecated; use the one-parameter add_model(model) instead.
Adds the indicated already-loaded model to the pool.
The model will always replace any previously-loaded model in the pool that had the same filename.
static int garbageCollect | ( | ) | [static] |
Releases only those models in the pool that have a reference count of exactly 1; i.e.
only those models that are not being used outside of the pool. Returns the number of models released.
Returns true if the model has ever been loaded, false otherwise.
static listContents | ( | ) | [static] |
Lists the contents of the model pool to cout.
static listContents | ( | ostream | out | ) | [static] |
Lists the contents of the model pool to the indicated output stream.
static ModelRoot loadModel | ( | Filename const | filename, |
LoaderOptions const | options | ||
) | [static] |
Loads the given filename up as a model, if it has not already been loaded, and returns the new model.
If a model with the same filename was previously loaded, returns that one instead. If the model file cannot be found, returns NULL.
Loads the given filename up as a model, if it has not already been loaded, and returns the new model.
If a model with the same filename was previously loaded, returns that one instead. If the model file cannot be found, returns NULL.
static releaseAllModels | ( | ) | [static] |
Releases all models in the pool and restores the pool to the empty state.
static releaseModel | ( | Filename const | filename | ) | [static] |
Removes the indicated model from the pool, indicating it will never be loaded again; the model may then be freed.
If this function is never called, a reference count will be maintained on every model every loaded, and models will never be freed.
This version of this method is deprecated; use release_model(model) instead.
static releaseModel | ( | ModelRoot | model | ) | [static] |
Removes the indicated model from the pool, indicating it will never be loaded again; the model may then be freed.
If this function is never called, a reference count will be maintained on every model every loaded, and models will never be freed.
The model's get_fullpath() value should not have been changed during its lifetime, or this function may fail to locate it in the pool.
static bool verifyModel | ( | Filename const | filename | ) | [static] |
Loads the given filename up as a model, 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_model() with the same model name will return a valid Node pointer.
