public final class NewsOrigin

This class describe pair of "news feed" and "news source", where "news source" is subdivision of feed, as each feed provide NewsEvents from one or more sources.

Origin can be exact, with fixed feed and source, and can be a mask, where feed, source or both are set to '*'.

Each NewsEvent's origin is always exact.

Origins with masks can be used as filters for NewsEvents.

String representation of origin is <feed>:<source>, where <feed> is alphanumeric string which starts from letter and <source> is arbitrary string of printable characters.

When NewsOrigin is created, empty <feed> or <source> is interpreted as * and string without : (semicolon) is interpreted as <feed>:*.

Empty string is special value that means "nothing".
