/**
* The model of an Eclipse resource filter matcher.
* <p>
* The matcher decides when the containing filter (or containing matcher) applies. The
* matcher configures things like whether this ResourceFilter matches resources by
* name, project relative path, location, last modified, etc. Eclipse has many types
* of built-in matchers and it is possible to specify the id and arguments for custom
* matchers using this model.
* <p>
* A matcher must have an id. It may have either a custom string argument or a set of nested
* child matchers (e.g. an 'or' matcher will have several nested condition matchers).
* <p>
* For more documentation on usage with examples, see {@link ResourceFilter}.
