Constructor Detail

ConnectionSpy

public ConnectionSpy(java.sql.Connection realConnection)

Create a new ConnectionSpy that wraps a given Connection.

Parameters:

realConnection - "real" Connection that this ConnectionSpy wraps.

ConnectionSpy

public ConnectionSpy(java.sql.Connection realConnection,
                     net.sf.log4jdbc.RdbmsSpecifics rdbmsSpecifics)

Create a new ConnectionSpy that wraps a given Connection.

Parameters:

realConnection - "real" Connection that this ConnectionSpy wraps.

rdbmsSpecifics - the RdbmsSpecifics object for formatting logging appropriate for the Rdbms used.

Method Detail

getRealConnection

public java.sql.Connection getRealConnection()

Get the real underlying Connection that this ConnectionSpy wraps.

Returns:

the real underlying Connection.

getOpenConnectionsDump

public static java.lang.String getOpenConnectionsDump()

Get a dump of how many connections are open, and which connection numbers are open.

Returns:

an open connection dump.

getConnectionNumber

public java.lang.Integer getConnectionNumber()

Description copied from interface: Spy

Get the connection number. In general, this is used to track which underlying connection is being used from the database. The number will be incremented each time a new Connection is retrieved from the real underlying jdbc driver. This is useful for debugging and tracking down problems with connection pooling.

Specified by:

getConnectionNumber in interface Spy

Returns:

the connection instance number.

getClassType

public java.lang.String getClassType()

Description copied from interface: Spy

Get the type of class being spied upon. For example, "Statement", "ResultSet", etc.

Specified by:

getClassType in interface Spy

Returns:

a description of the type of class being spied upon.
