Interface ConnectionCustomizer

All Known Implementing Classes:

AbstractConnectionCustomizer, TestConnectionCustomizer

public interface ConnectionCustomizer

Implementations of this interface should be immutable, and should offer public, no argument constructors.

The methods are handed raw, physical database Connections, not c3p0-generated proxies.

Although c3p0 will ensure this with respect to state controlled by standard JDBC methods, any modifications of vendor-specific state shold be made consistently so that all Connections in the pool are interchangable.

Method Summary

void	onAcquire(java.sql.Connection c, java.lang.String parentDataSourceIdentityToken) Called immediately after a Connection is acquired from the underlying database for incorporation into the pool.
void	onCheckIn(java.sql.Connection c, java.lang.String parentDataSourceIdentityToken) Called immediately after a Connection is checked in, prior to reincorporation into the pool.
void	onCheckOut(java.sql.Connection c, java.lang.String parentDataSourceIdentityToken) Called immediately before a Connection is made available to a client upon checkout.
void	onDestroy(java.sql.Connection c, java.lang.String parentDataSourceIdentityToken) Called immediately before a Connection is destroyed after being removed from the pool.

Method Detail

onAcquire

void onAcquire(java.sql.Connection c,
               java.lang.String parentDataSourceIdentityToken)
               throws java.lang.Exception

Called immediately after a Connection is acquired from the underlying database for incorporation into the pool.

This method is only called once per Connection. If standard JDBC Connection properties are modified [holdability, transactionIsolation, readOnly], those modifications will override defaults throughout the Connection's tenure in the pool.

Throws:

java.lang.Exception

onDestroy

void onDestroy(java.sql.Connection c,
               java.lang.String parentDataSourceIdentityToken)
               throws java.lang.Exception

Called immediately before a Connection is destroyed after being removed from the pool.

Throws:

java.lang.Exception

onCheckOut

void onCheckOut(java.sql.Connection c,
                java.lang.String parentDataSourceIdentityToken)
                throws java.lang.Exception

Called immediately before a Connection is made available to a client upon checkout.

Throws:

java.lang.Exception

onCheckIn

void onCheckIn(java.sql.Connection c,
               java.lang.String parentDataSourceIdentityToken)
               throws java.lang.Exception

Called immediately after a Connection is checked in, prior to reincorporation into the pool.

Throws:

java.lang.Exception
