===================================================================

.. currentmodule:: gi.repository.GObject





.. class:: ParamSpecPool(*args, **kwargs)
   :no-contents-entry:






A :obj:`~gi.repository.GObject.ParamSpecPool` maintains a collection of :obj:`~gi.repository.GObject.ParamSpec` which can be
quickly accessed by owner and name.

The implementation of the :obj:`~gi.repository.GObject.Object` property system uses such a pool to
store the :obj:`~gi.repository.GObject.ParamSpec` of the properties all object types.
