SharedTaskPool

Added in version 1.20.

class SharedTaskPool(**properties: Any)

Superclasses: TaskPool, Object, InitiallyUnowned, Object

The SharedTaskPool object.

Constructors

class SharedTaskPool

classmethod new() → TaskPool

Create a new shared task pool. The shared task pool will queue tasks on a maximum number of threads, 1 by default.

Do not use a SharedTaskPool to manage potentially inter-dependent tasks such as pad tasks, as having one task waiting on another to return before returning would cause obvious deadlocks if they happen to share the same thread.

Added in version 1.20.

Methods

class SharedTaskPool

get_max_threads() → int

Added in version 1.20.

set_max_threads(max_threads: int) → None

Update the maximal number of threads the pool may spawn. When the maximal number of threads is reduced, existing threads are not immediately shut down, see set_max_threads().

Setting max_threads to 0 effectively freezes the pool.

Added in version 1.20.

Parameters:

max_threads – Maximum number of threads to spawn.
