Class DomainBoundaries

java.lang.Object
  org.semanticdesktop.aperture.datasource.config.DomainBoundaries

public class DomainBoundaries
extends Object

A DomainBoundaries uses UrlPatterns (regular expressions or substrings checks) to determine whether a URL belongs to a DataSource domain or not.

Each DomainBoundaries maintains lists of include and exclude patterns. A URL is matched against these two pattern lists to determine whether it is inside or outside the domain. A URL is inside the domain when it matches at least one of the include patterns but none of the exclude patterns. In case no include patterns are specified, all URLs that don't match any of the exclude patterns are included.
