javax.sql.rowset
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.

Since:

1.7

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 ServiceLoader API. The ServiceLoader API will look for a class name in the file META-INF/services/javax.sql.rowset.RowSetFactory in jars available to the runtime. For example, to have the the RowSetFactory implementation com.sun.rowset.RowSetFactoryImpl loaded, the entry in META-INF/services/javax.sql.rowset.RowSetFactory would be:
  • com.sun.rowset.RowSetFactoryImpl
• Platform default RowSetFactory instance.

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

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 of javax.sql.rowset.RowSetFactory.

cl - ClassLoader used to load the factory class. If null current Thread's context classLoader is used to load the factory class.

Returns:

New instance of a RowSetFactory

Throws:

SQLException - if factoryClassName is null, or the factory class cannot be loaded, instantiated.
