oracle.toplink.queryframework
Class ScrollableCursorPolicy

java.lang.Object
oracle.toplink.internal.queryframework.ContainerPolicy
oracle.toplink.queryframework.CursorPolicy
oracle.toplink.queryframework.ScrollableCursorPolicy

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class ScrollableCursorPolicy

extends CursorPolicy

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);
