The Query interface provides a way to encapsulate a registry query to be handled by a DeclarativeQueryManager. A Query object is created by calling the createQuery( ) method of the DeclarativeQueryManager whose executeQuery( ) method is eventually used to perform the search operation that it specifies. The query manager may choose to return a private object implementing Query that represents the query string in a form that is suitable for the means that are eventually used to action it. The getType( ) methods return the type of query that the Query object represents (such as QUERY_TYPE_SQL), while toString( ) returns a string representation of the query. DeclarativeQueryManagers are supported only by level 1 providers, but only queries of type QUERY_TYPE_EBXML_FILTER_QUERY are required to be supported.
