Purpose of this class is cover incompatibility in ``psutil.Process`` class and provide interface of new version. It allows using new interface even with old version of ``psutil``. Note that, for performance reasons, process information is cached at object creation. To force a refresh, invoke the ``rebuild_cache()`` method.

For performance reasons, instances are cached based on PID, and multiple instantiations of a ``Process`` object with the same PID will return the same object. To clear the cache, invoke ``Process.reset_cache()``. Additionally, as with ``ProcessWrapper``, process information is cached at object creation. To force a refresh, invoke the ``rebuild_cache()`` method on the object. c C s | j |j kS )zBFor our purposes, two processes are equal when they have same name)r �r �processr r r �__eq__� s zProcess.__eq__c C s | � |� S r )rM rK r r r �__ne__� s zProcess.__ne__c C s t | j�S r )�hashr r r r r �__hash__� s zProcess.__hash__� �?c C sT t dd| gttd�}t||j�}z$|�� |�� |jdkW |�� S |�� 0 dS )z� Process arguments could be referring to files on remote filesystems and os.path.isfile will hang forever if the shared FS is offline.
