Return type


clear() → None

Removes all AsyncTasks from the collection.

Return type


getNumTasks() → size_t

Returns the number of AsyncTasks in the collection.

Return type


getTask(index: size_t) → AsyncTask

Returns the nth AsyncTask in the collection.

Return type


getTasks() → list
hasTask(task: AsyncTask) → bool

Returns true if the indicated AsyncTask appears in this collection, false otherwise.

output(out: ostream) → None

Writes a brief one-line description of the AsyncTaskCollection to the indicated output stream.
