Description

It is the base class for every object in mission-control. It defines a set of virtual functions and set of corresponding action signals. all virtual functions results in emission of their corresponding action signals. The virtual functions define states of the object, such as memory conserved state, connected state, locked state, low power state, lit state, sleeping state etc. Each of the object states can also be queried independently as properties.

There are also some action signals such as abort, which is used to notify other objects holding hard references to it to release them (this object should then automatically die since all held references are released). It is mandatory for all other objects that hold a hard reference to it to listen for this signal and release the reference in signal handler.

Concrete derived classes should override the sate methods to implement object specific state managements.
