Method Detail

getEmbedConnection

final EmbedConnection getEmbedConnection()

Return a reference to the EmbedConnection

getConnectionSynchronization

final java.lang.Object getConnectionSynchronization()

Return an object to be used for connection synchronization.

handleException

final java.sql.SQLException handleException(java.lang.Throwable t)
                                     throws java.sql.SQLException

Handle any exception.

Throws:

java.sql.SQLException - thrown if can't handle

See Also:

EmbedConnection.handleException(java.lang.Throwable)

needCommit

final void needCommit()

If Autocommit is on, note that a commit is needed.

See Also:

EmbedConnection.needCommit

commitIfNeeded

final void commitIfNeeded()
                   throws java.sql.SQLException

Perform a commit if one is needed.

Throws:

java.sql.SQLException - thrown on failure

See Also:

EmbedConnection.commitIfNeeded()

commitIfAutoCommit

final void commitIfAutoCommit()
                       throws java.sql.SQLException

Perform a commit if autocommit is enabled.

Throws:

java.sql.SQLException - thrown on failure

See Also:

EmbedConnection.commitIfNeeded()

setupContextStack

final void setupContextStack()
                      throws java.sql.SQLException

Setup the context stack (a.k.a. context manager) for this connection.

Throws:

java.sql.SQLException - thrown on failure

getCal

java.util.Calendar getCal()

Get and save a unique calendar object for this JDBC object. No need to synchronize because multiple threads should not be using a single JDBC object. Even if they do there is only a small window where each would get its own Calendar for a single call.
