# ResourceFilterMatcher

interface ResourceFilterMatcher

The model of an Eclipse resource filter matcher.

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.

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).

For more documentation on usage with examples, see ResourceFilter.
