## com.mysql.jdbc
Interface ConnectionLifecycleInterceptor

All Superinterfaces:
  Extension

    public interface ConnectionLifecycleInterceptor

extends Extension

Implementors of this interface can be installed via the "connectionLifecycleInterceptors" configuration property and receive events and alter behavior of "lifecycle" methods on our connection implementation. The driver will create one instance of a given interceptor per-connection.

Method Summary
`void` | `close()` Called when an application calls Connection.close(), before the driver processes its own internal logic for close.
`boolean` | `commit()` Called when an application calls Connection.commit(), before the driver processes its own internal logic for commit().
`boolean` | `rollback()` Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback().
`boolean` | `rollback(java.sql.Savepoint s)` Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback().
`boolean` | `setAutoCommit(boolean flag)` Called when an application calls Connection.setAutoCommit(), before the driver processes its own internal logic for setAutoCommit().
`boolean` | `setCatalog(java.lang.String catalog)` Called when an application calls Connection.setCatalog(), before the driver processes its own internal logic for setCatalog().
`boolean` | `transactionBegun()` Called when the driver has been told by the server that a transaction is now in progress (when one has not been currently in progress).
`boolean` | `transactionCompleted()` Called when the driver has been told by the server that a transaction has completed, and no transaction is currently in progress.

Method Detail

### close

    void close()
               throws java.sql.SQLException

  Called when an application calls Connection.close(), before the driver processes its own internal logic for close.

  Throws:
    `java.sql.SQLException`

### commit

    boolean commit()
                   throws java.sql.SQLException

  Called when an application calls Connection.commit(), before the driver processes its own internal logic for commit(). Interceptors should return "true" if the driver should perform its own internal logic for commit(), or "false" if not.

  Returns:
    "true" if the driver should perform its own internal logic for commit(), or "false" if not.
  Throws:
    `java.sql.SQLException` - if an error occurs

### rollback

    boolean rollback()
                     throws java.sql.SQLException

  Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback(). Interceptors should return "true" if the driver should perform its own internal logic for rollback(), or "false" if not.

  Returns:
    "true" if the driver should perform its own internal logic for rollback(), or "false" if not.
  Throws:
    `java.sql.SQLException` - if an error occurs

### rollback

    boolean rollback(java.sql.Savepoint s)
                     throws java.sql.SQLException

  Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback(). Interceptors should return "true" if the driver should perform its own internal logic for rollback(), or "false" if not.

  Returns:
    "true" if the driver should perform its own internal logic for rollback(), or "false" if not.
  Throws:
    `java.sql.SQLException` - if an error occurs

### setAutoCommit

    boolean setAutoCommit(boolean flag)
                          throws java.sql.SQLException

  Called when an application calls Connection.setAutoCommit(), before the driver processes its own internal logic for setAutoCommit(). Interceptors should return "true" if the driver should perform its own internal logic for setAutoCommit(), or "false" if not.

  Returns:
    "true" if the driver should perform its own internal logic for setAutoCommit(), or "false" if not.
  Throws:
    `java.sql.SQLException` - if an error occurs

### setCatalog

    boolean setCatalog(java.lang.String catalog)
                       throws java.sql.SQLException

  Called when an application calls Connection.setCatalog(), before the driver processes its own internal logic for setCatalog(). Interceptors should return "true" if the driver should perform its own internal logic for setCatalog(), or "false" if not.

  Returns:
    "true" if the driver should perform its own internal logic for setCatalog(), or "false" if not.
  Throws:
    `java.sql.SQLException` - if an error occurs

### transactionBegun

    boolean transactionBegun()
                             throws java.sql.SQLException

  Called when the driver has been told by the server that a transaction is now in progress (when one has not been currently in progress).

  Throws:
    `java.sql.SQLException`

### transactionCompleted

    boolean transactionCompleted()
                                 throws java.sql.SQLException
