Class RowSetProvider
- java.lang.Object
-
- javax.sql.rowset.RowSetProvider
-
public class RowSetProvider extends Object
A factory API that enables applications to obtain aRowSetFactoryimplementation that can be used to create different types ofRowSetimplementations.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.debugto any value butfalse.- Since:
- 1.7

Method Detail
newFactory
public static RowSetFactory newFactory() throws SQLException
Creates a new instance of a
RowSetFactoryimplementation. This method uses the following look up order to determine theRowSetFactoryimplementation 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 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

- The System property
newFactory
public static RowSetFactory newFactory(String factoryClassName, ClassLoader cl) throws SQLException
Creates a new instance of a
RowSetFactoryfrom 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
RowSetFactoryit 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
