- org.apache.tomcat.dbcp.dbcp2.datasources.InstanceKeyDataSource

- Direct Known Subclasses:
PerUserPoolDataSource,SharedPoolDataSource
public abstract class InstanceKeyDataSource extends java.lang.Object implements javax.sql.DataSource, javax.naming.Referenceable, java.io.Serializable, java.lang.AutoCloseableThe base class for
SharedPoolDataSourceandPerUserPoolDataSource. Many of the configuration properties are shared and defined here. This class is declared public in order to allow particular usage with commons-beanutils; do not make direct use of it outside of commons-dbcp2.A J2EE container will normally provide some method of initializing the
DataSourcewhose attributes are presented as bean getters/setters and then deploying it via JNDI. It is then available to an application as a source of pooled logical connections to the database. The pool needs a source of physical connections. This source is in the form of aConnectionPoolDataSourcethat can be specified via thesetDataSourceName(String)used to lookup the source via JNDI.Although normally used within a JNDI environment, A DataSource can be instantiated and initialized as any bean. In this case the
ConnectionPoolDataSourcewill likely be instantiated in a similar manner. This class allows the physical source of connections to be attached directly to this pool using thesetConnectionPoolDataSource(ConnectionPoolDataSource)method.The dbcp package contains an adapter,
DriverAdapterCPDS, that can be used to allow the use ofDataSource's based on this class with JDBC driver implementations that do not supply aConnectionPoolDataSource, but still provide aDriverimplementation.The package documentation contains an example using Apache Tomcat and JNDI and it also contains a non-JNDI example.
