构造器详细资料

C3P0ConnectionProvider

public C3P0ConnectionProvider(ProviderConfig ProviderConfig)

方法详细资料

getProviderConfig

public ProviderConfig getProviderConfig()

指定者:

getProviderConfig 在接口中 ConnectionProvider

setProviderConfig

public void setProviderConfig(ProviderConfig ProviderConfig)

isPooled

public boolean isPooled()

从接口复制的说明: ConnectionProvider

Returns true if this connection provider provides connections out of a connection pool. Implementing and using connection providers that are pooled is strongly recommended, as they greatly increase the speed of Jive.

指定者:

isPooled 在接口中 ConnectionProvider

返回:

true if the Connection objects returned by this provider are pooled.

createDataSource

public com.mchange.v2.c3p0.ComboPooledDataSource createDataSource()

getConnection

public Connection getConnection()
                         throws SQLException

从接口复制的说明: ConnectionProvider

Returns a database connection. When a Jive component is done with a connection, it will call the close method of that connection. Therefore, connection pools with special release methods are not directly supported by the connection provider infrastructure. Instead, connections from those pools should be wrapped such that calling the close method on the wrapper class will release the connection from the pool.

指定者:

getConnection 在接口中 ConnectionProvider

返回:

a Connection object.

抛出:

SQLException

start

public void start()

从接口复制的说明: ConnectionProvider

Starts the connection provider. For some connection providers, this will be a no-op. However, connection provider users should always call this method to make sure the connection provider is started.

指定者:

start 在接口中 ConnectionProvider

restart

public void restart()

从接口复制的说明: ConnectionProvider

This method should be called whenever properties have been changed so that the changes will take effect.

指定者:

restart 在接口中 ConnectionProvider

destroy

public void destroy()

从接口复制的说明: ConnectionProvider

Tells the connection provider to destroy itself. For many connection providers, this will essentially result in a no-op. However, connection provider users should always call this method when changing from one connection provider to another to ensure that there are no dangling database connections.

指定者:

destroy 在接口中 ConnectionProvider

finalize

public void finalize()

覆盖:

finalize 在类中 Object
