Panda3D
|
This class object manages a single asynchronous request to flatten a model. The model will be duplicated and flattened in a sub-thread (if threading is available), without affecting the original model; and when the result is done it may be retrieved from this object. More...
Public Member Functions | |
__init__ (PandaNode orig) | |
Create a new ModelFlattenRequest, and add it to the loader via load_async(), to begin an asynchronous load. More... | |
PandaNode | getModel () |
Returns the flattened copy of the model. It is an error to call this unless is_ready() returns true. More... | |
PandaNode | getOrig () |
Returns the original, unflattened node. More... | |
bool | isReady () |
Returns true if this request has completed, false if it is still pending. When this returns true, you may retrieve the model loaded by calling get_result(). More... | |
![]() | |
clearDelay () | |
Removes any delay specified for the task. The next time the task is added to the queue, it will run immediately. This does not affect the task's wake time if it has already been added to the queue. More... | |
clearName () | |
Resets the task's name to empty. More... | |
double | getAverageDt () |
Returns the average amount of time elapsed during each of the task's previous run cycles, in seconds. More... | |
double | getDelay () |
Returns the delay value that has been set via set_delay, if any. More... | |
str | getDoneEvent () |
Returns the event name that will be triggered when the task finishes. See set_done_event(). More... | |
double | getDt () |
Returns the amount of time elapsed during the task's previous run cycle, in seconds. More... | |
int | getElapsedFrames () |
Returns the number of frames that have elapsed since the task was started, according to the task manager's clock. More... | |
double | getElapsedTime () |
Returns the amount of time that has elapsed since the task was started, according to the task manager's clock. More... | |
AsyncTaskManager | getManager () |
Returns the AsyncTaskManager that this task is active on. This will be NULL if the state is S_inactive. More... | |
double | getMaxDt () |
Returns the maximum amount of time elapsed during any one of the task's previous run cycles, in seconds. More... | |
str | getNamePrefix () |
Returns the initial part of the name, up to but not including any trailing digits following a hyphen or underscore. More... | |
int | getPriority () |
Returns the task's current priority value. See set_priority(). More... | |
object | getPythonObject () |
Returns the Python object that was specified to set_python_object(), if any, or None if no object was specified. More... | |
int | getSort () |
Returns the task's current sort value. See set_sort(). More... | |
int | getStartFrame () |
Returns the frame number at which the task was started, according to the task manager's clock. More... | |
double | getStartTime () |
Returns the time at which the task was started, according to the task manager's clock. More... | |
AsyncTask::State | getState () |
Returns the current state of the task. More... | |
str | getTaskChain () |
Returns the AsyncTaskChain on which this task will be running. Each task chain runs tasks independently of the others. More... | |
AtomicAdjust::Integer | getTaskId () |
Returns a number guaranteed to be unique for each different AsyncTask object in the universe. More... | |
double | getWakeTime () |
If this task has been added to an AsyncTaskManager with a delay in effect, this returns the time at which the task is expected to awaken. It has no meaning if the task has not yet been added to a queue, or if there was no delay in effect at the time the task was added. More... | |
bool | hasDelay () |
Returns true if a delay has been set for this task via set_delay(), or false otherwise. More... | |
bool | isAlive () |
Returns true if the task is currently active or sleeping on some task chain, meaning that it will be executed in its turn, or false if it is not active. If the task has recently been removed while it is in the middle of execution, this will return false, because the task will not run again once it finishes. More... | |
output (Ostream out) | |
recalcWakeTime () | |
If the task is currently sleeping on a task chain, this resets its wake time to the current time. More... | |
remove () | |
Removes the task from its active manager, if any, and makes the state S_inactive (or possible S_servicing_removed). This is a no-op if the state is already S_inactive. More... | |
setDelay (double delay) | |
Specifies the amount of time, in seconds, by which this task will be delayed after it has been added to the AsyncTaskManager. At least the specified amount of time (and possibly more) will elapse before the task begins. More... | |
setDoneEvent (str done_event) | |
Sets the event name that will be triggered when the task finishes. This should only be called before the task has been started, or after it has finished and before it is about to be restarted (i.e. when get_state() returns S_inactive). More... | |
setName (str name) | |
setPriority (int priority) | |
Specifies a priority value for this task. In general, tasks with a higher priority value are executed before tasks with a lower priority value (but only for tasks with the same sort value). More... | |
setPythonObject (object python_object) | |
Specifies an arbitrary Python object that will be piggybacked on the task object. More... | |
setSort (int sort) | |
Specifies a sort value for this task. Within a given AsyncTaskManager, all of the tasks with a given sort value are guaranteed to be completed before any tasks with a higher sort value are begun. More... | |
setTaskChain (str chain_name) | |
Specifies the AsyncTaskChain on which this task will be running. Each task chain runs tasks independently of the others. More... | |
![]() | |
TypeHandle | getType () |
Derived classes should override this function to return get_class_type(). More... | |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More... | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. More... | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More... | |
bool | unref () |
Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More... | |
![]() | |
__init__ (const Namable copy) | |
__init__ (str initial_name) | |
clearName () | |
Resets the Namable's name to empty. More... | |
str | getName () |
bool | hasName () |
Returns true if the Namable has a nonempty name set, false if the name is empty. More... | |
Namable | operator= (const Namable other) |
output (Ostream out) | |
Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this. More... | |
setName (str name) | |

PandaNode getModel | ( | ) |
Returns the flattened copy of the model. It is an error to call this unless is_ready() returns true.
PandaNode getOrig | ( | ) |
Returns the original, unflattened node.
bool isReady | ( | ) |
Returns true if this request has completed, false if it is still pending. When this returns true, you may retrieve the model loaded by calling get_result().
