public class ScrollableCursorPolicy
PUBLIC: ScrollableCursorPolicy allows for additional options to be specified for ReadAllQuery or DataReadQuery. These options are passed through to the JDBC result set, the JDBC driver must support JDBC2 scrolling cursors and the options used. Example:
ScrollableCursorPolicy policy = new ScrollableCursorPolicy()
policy.setResultSetType(ScrollableCursorPolicy.TYPE_SCROLL_INSENSITIVE);
query.useScrollableCursor(policy);
