Build: Defines all the operations during which the Dashboard is triggered from a dormant state to an active state. This starts from the moment the Dashboard is called up till shortly after the UI is made visible.
Collapse: Defines the sequence of operations during which the Dashboard is made to terminate all processes and disposes off the UI. After this state, Dashboard is literally "dead" - no background tak runs - untill it is being rebuilt.
Self silent: Used to describe methods that contained and suppress
any potential exceptions within their blocks. Such methods, depending on the return type, may return null object or a negative number.
