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
ServiceLoader
API. TheServiceLoader
API will look for a class name in the fileMETA-INF/services/javax.sql.rowset.RowSetFactory
in jars available to the runtime. For example, to have the RowSetFactory implementationcom.sun.rowset.RowSetFactoryImpl
loaded, the entry inMETA-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 - Since:
- 1.7

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
-ClassLoader
used to load the factory class. Ifnull
currentThread
's context classLoader is used to load the factory class. - Returns:
- New instance of a
RowSetFactory
- Throws:

, or the factory class cannot be loaded, instantiated. - Since:
