java.lang.Objectjavax.sql.rowset.RowSetFactory
public abstract class RowSetFactory
A factory API that enables applications to configure and obtain different types of RowSet
implementations.
Example:
RowSetFactory aFactory = RowSetFactory.newInstance(); CachedRowSet crs = aFactory.createCachedRowSet(); ... RowSetFactory rsf = RowSetFactory.newInstance("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
.

public abstract CachedRowSetcreateCachedRowSet() throws SQLException
Creates a new instance of a CachedRowSet.
SQLException
- if a CachedRowSet cannot be created. public abstract FilteredRowSetcreateFilteredRowSet() throws SQLException
Creates a new instance of a FilteredRowSet.
SQLException
- if a FilteredRowSet cannot be created. public abstract JdbcRowSetcreateJdbcRowSet() throws SQLException
Creates a new instance of a JdbcRowSet.
SQLException
- if a JdbcRowSet cannot be created. public abstract JoinRowSetcreateJoinRowSet() throws SQLException
Creates a new instance of a JoinRowSet.
SQLException
- if a JoinRowSet cannot be created. public abstract WebRowSetcreateWebRowSet() throws SQLException
Creates a new instance of a WebRowSet.
SQLException
- if a WebRowSet cannot be created. public static RowSetFactorynewInstance() 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:
javax.sql.rowset.RowsetFactory
. For example: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
RowSetFactory
instance. Once an application has obtained a reference to a RowSetFactory
, it can use the factory to obtain RowSet instances.
RowSetFactory
SQLException
- if the default factory class cannot be loaded, instantiated. The cause will be set to actual Exception ServiceLoader
public static RowSetFactorynewInstance(java.lang.String factoryClassName, java.lang.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.
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. RowSetFactory
SQLException
- if factoryClassName
is null
, or the factory class cannot be loaded, instantiated. newInstance()
