Constructor Details

DerbyTable

public DerbyTable(JdbcTemplate jdbcTemplate,
 DerbyDatabase database,
 DerbySchema schema,
 String name)

Creates a new Derby table.

Parameters:

jdbcTemplate - The Jdbc Template for communicating with the DB.

database - The database-specific support.

schema - The schema this table lives in.

name - The name of the table.

Method Details

doDrop

protected void doDrop()
               throws SQLException

Specified by:

doDrop in class BaseSchemaObject<DerbyDatabase,DerbySchema>

Throws:

SQLException - when the drop failed.

doExists

protected boolean doExists()
                    throws SQLException

Description copied from class: BaseTable

Checks whether this table exists.

Specified by:

doExists in class BaseTable<DerbyDatabase,DerbySchema>

Throws:

SQLException - when the check failed.

doLock

protected void doLock()
               throws SQLException

Description copied from class: BaseTable

Locks this table in this schema using a read/write pessimistic lock until the end of the current transaction. Note that unlock() still needs to be called even if your database unlocks the table implicitly (in which case doUnlock() may be a no-op) in order to maintain the lock count correctly.

Specified by:

doLock in class BaseTable<DerbyDatabase,DerbySchema>

Throws:

SQLException - when this table in this schema could not be locked.
