Examples of de.innovationgate.webgate.api.WGResultSet

de.innovationgate.webgate.api.WGResultSet
Generic interface for result sets that are returned by the WGAPI. The WGResultSet implementation should: - Filter out contents based on the fields "validfrom" and "validto" if the query option "enhanced" is either omitted or set to true - Filter out contents based on the field "visible", if the query option "enhanced" is either omitted or set to true
