Examples of ConnectionPool

anvil.database.ConnectionPool

Pool for storing limited amount of connections as PooledConnection. Pool is used by ConnectionAccessQueue which takes care of the situations when connections aren't immediately available.

Methods which might alter the connection vectors are internally synchronized so that only one thread at a time can perform operations on them. However several threads may be creating connections at the same time.

com.atomikos.datasource.pool.ConnectionPool
com.atomikos.jdbc.ConnectionPool

A connection pooling implementation. This class is NOT meant to be used by the application directly. Rather, a DataSource object should wrap this class. @deprecated As of release 3.3, the newer pool should be used instead.
com.caucho.env.dbpool.ConnectionPool
Implementation of the connection manager.

com.icentris.sql.ConnectionPool
com.l2client.dao.derby.ConnectionPool
A pool of sql connections, which are already initialized. The max number of held connections is configured by MAX_CONNECTIONS. The conections are stored in a blocking queue, so future requests will wait until a connection is returned. Used as a singleton via ConnectionPoool.getInstance()
com.squareup.okhttp.ConnectionPool

de.zib.scalaris.ConnectionPool
Implements a simple (thread-safe) connection pool for Scalaris connections. @author Nico Kruber, kruber@zib.de @version 3.7 @since 3.7
net.dataforte.cassandra.pool.ConnectionPool
org.apache.activemq.jms.pool.ConnectionPool
Holds a real JMS connection along with the session pools associated with it.
Instances of this class are shared amongst one or more PooledConnection object and must track the session objects that are loaned out for cleanup on close as well as ensuring that the temporary destinations of the managed Connection are purged when all references to this ConnectionPool are released.
org.apache.aries.transaction.jms.internal.ConnectionPool
Holds a real JMS connection along with the session pools associated with it.
org.apache.hadoop.hbase.jdbc.ConnectionPool
org.apache.tomcat.jdbc.pool.ConnectionPool
Implementation of simple connection pool. The ConnectionPool uses a {@link PoolProperties} object for storing all the meta information about the connection pool.As the underlying implementation, the connection pool uses {@link java.util.concurrent.BlockingQueue} to store active and idle connections.A custom implementation of a fair {@link FairBlockingQueue} blocking queue is provided with the connection pool itself. @author Filip Hanik @version 1.0
org.apache.turbine.util.db.pool.ConnectionPool
This class implements a simple connection pooling scheme. Multiple pools are available through use of the PoolBrokerService. @author Costas Stergiou @author Frank Y.

org.eclipse.persistence.sessions.server.ConnectionPool

Purpose: Used to specify how connection should be pooled in a server session. @see ServerSession
org.fcrepo.server.storage.ConnectionPool
Provides a dispenser for database Connection Pools. @author Ross Wayland @author Chris Wilper
org.fto.jthink.jdbc.ConnectionPool
连接池, 可为每一个连接ID，创建一个连接池,连接ID在fto-jthink.xml文件中配置。此连接池不创建具体连接，它只对连接统一进行管理。如果应用服务器已经提供了对数据源的池管理功能，建议不要使用此连接池，即用JNDIConnectionFactory工厂创建的连接不要使用此连接池。而用DirectConnectionFactory工厂创建的连接推荐使用此连接池。是否使用连接池来管理连接，只须在fto-jthink.xml中的数据源配置中设置即可。
```
 历史更新记录: 2005-06-25  创建此类型 2005-10-29  修改了closeConnectionPool()方法 2008-10-24  在PooledConnection中记录默认事务隔离级别，当返回连接时将恢复默认事务隔离级别 2008-10-30  解决以前没有处理的问题，连接池满的检查

org.serviceconnector.net.connection.ConnectionPool
The Class ConnectionPool. Concrete implementation of connection pooling.

This connection pool takes care of following listed points:
- creating / destroying of connections
- observing the max numbers of connections
- keeping a minimum of connections active
- disconnect connection after Constants.DEFAULT_NR_OF_KEEP_ALIVES_TO_CLOSE
- destroying connection pool, destroys all connections

optional functions:
- closing connection after getting it back
- initializing pool by starting a minimum of connections immediately
- observing connection idle timeout and sending keep alive messages to refresh firewall
- force closing of a specific connection, very useful if connection has a curious state @author JTraber
