Pythonic singleton #147

Closed clstaudt closed 1 year ago

clstaudt commented 1 year ago

In Python any class can be easily turned into a singleton by adding a generic decorator.

This removes the need for special implementations of the singleton pattern like SingletonDataFrame.

The general idea here is to add new classes, layers and indirections only sparingly:

TimeTrackingView -> TimeTrackingIntent -> TimeTrackingDataFrameSource
is better than TimeTrackingView -> TimeTrackingIntent -> TimetrackingDataFrameSource -> SingletonDataFrame.

Complexity considered harmful.
