Class RowSetProvider
- java.lang.Object
-
- javax.sql.rowset.RowSetProvider
public class RowSetProvider extends Object
A factory API that enables applications to obtain a RowSetFactory implementation that can be used to create different types of RowSet implementations.
Example:
RowSetFactory aFactory = RowSetProvider.newFactory();
CachedRowSet crs = aFactory.createCachedRowSet();
...
RowSetFactory rsf = RowSetProvider.newFactory("com.sun.rowset.RowSetFactoryImpl", null);
WebRowSet wrs = rsf.createWebRowSet(); Tracing of this class may be enabled by setting the System property javax.sql.rowset.RowSetFactory.debug to any value but false.

Method Detail
newFactory
public static RowSetFactory newFactory()
throws SQLException Creates a new instance of a RowSetFactory implementation. This method uses the following look up order to determine the RowSetFactory implementation class to load:
- The System property
javax.sql.rowset.RowSetFactory. For example:- -Djavax.sql.rowset.RowSetFactory=com.sun.rowset.RowSetFactoryImpl
- The
ServiceLoaderAPI. TheServiceLoaderAPI will look for a class name in the fileMETA-INF/services/javax.sql.rowset.RowSetFactoryin jars available to the runtime. For example, to have the RowSetFactory implementationcom.sun.rowset.RowSetFactoryImplloaded, the entry inMETA-INF/services/javax.sql.rowset.RowSetFactorywould be:-
com.sun.rowset.RowSetFactoryImpl
-
- Platform default
RowSetFactoryinstance.
Once an application has obtained a reference to a RowSetFactory, it can use the factory to obtain RowSet instances.
- Returns:
- New instance of a
RowSetFactory - Throws:
-
SQLException- if the default factory class cannot be loaded, instantiated. The cause will be set to actual Exception - Since:
- 1.7

ServiceLoader
newFactory
public static RowSetFactory newFactory(String factoryClassName,
ClassLoader cl)
throws SQLException Creates a new instance of a RowSetFactory from the specified factory class name. This function is useful when there are multiple providers in the classpath. It gives more control to the application as it can specify which provider should be loaded.
Once an application has obtained a reference to a RowSetFactory it can use the factory to obtain RowSet instances.
- Parameters:
-
factoryClassName- fully qualified factory class name that provides an implementation ofjavax.sql.rowset.RowSetFactory. -
cl-ClassLoaderused to load the factory class. IfnullcurrentThread's context classLoader is used to load the factory class. - Returns:
- New instance of a
RowSetFactory - Throws:
-
SQLException- iffactoryClassNameisnull, or the factory class cannot be loaded, instantiated. - Since:
- 1.7
