All Implemented Interfaces:

java.io.Serializable, java.sql.Wrapper, javax.naming.Referenceable, javax.naming.spi.ObjectFactory, javax.sql.CommonDataSource, javax.sql.ConnectionPoolDataSource, javax.sql.DataSource

public class EmbeddedConnectionPoolDataSource40
extends org.apache.derby.jdbc.EmbeddedConnectionPoolDataSource
implements javax.sql.ConnectionPoolDataSource

EmbeddedConnectionPoolDataSource40 is Derby's ConnectionPoolDataSource implementation for the JDBC4.0 environment.

A ConnectionPoolDataSource is a factory for PooledConnection objects. An object that implements this interface will typically be registered with a JNDI service.

EmbeddedConnectionPoolDataSource40 supports the JDBC 4.0 specification for the J2SE 6.0 Java Virtual Machine environment. Use EmbeddedConnectionPoolDataSource if your application runs in the following environments:

• JDBC 3.0 - Java 2 - JDK 1.4, J2SE 5.0

EmbeddedConnectionPoolDataSource40 is serializable and referenceable.

See EmbeddedDataSource40 for DataSource properties.

Returns false unless interfaces is implemented

Specified by:

isWrapperFor in interface java.sql.Wrapper

Parameters:

interfaces - a Class defining an interface.

Returns:

true if this implements the interface or directly or indirectly wraps an object that does.

Throws:

java.sql.SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

unwrap

public <T> T unwrap(java.lang.Class<T> interfaces)
         throws java.sql.SQLException

Returns this if this class implements the interface

Specified by:

unwrap in interface java.sql.Wrapper

Parameters:

interfaces - a Class defining an interface

Returns:

an object that implements the interface

Throws:

java.sql.SQLExption - if no object if found that implements the interface

java.sql.SQLException
