Class JcrQueryResult

java.lang.Object
  org.modeshape.jcr.query.JcrQueryResult

All Implemented Interfaces:

QueryResult

Direct Known Subclasses:

JcrSqlQueryResult, XPathQueryResult

@NotThreadSafe
public class JcrQueryResult
extends Object
implements QueryResult

The results of a query. This is not thread-safe because it relies upon JcrSession, which is not thread-safe. Also, although the results of a query never change, the objects returned by the iterators may vary if the session information changes.
