Class Filter

posthog/models/filters/filter.py:53–127

Filters allow us to describe what events to show/use in various places in the system, for example Trends or Funnels. This object isn't a table in the database. It gets stored against the specific models itself as JSON. This class just allows for stronger typing of this object.
