| By extending this class it's possible to easily customize the behaviour of
a large number of methods in the
DbQueryManager class.
You're able to set the parameters of a
DbPreparedStatement before the actual execution of any logic by overriding the
DbPreparedStatementHandler.setParameters(DbPreparedStatement) setParameters method.
If you need to customize the entire query execution, you can override
the
DbPreparedStatementHandler.performUpdate(DbPreparedStatement) performUpdate and
DbPreparedStatementHandler.performQuery(DbPreparedStatement) performQuery methods. Note that these
methods are actually responsible for calling the
DbPreparedStatementHandler.setParameters(DbPreparedStatement) setParameters method, so if you
override them you either have to call this method yourself or include the
code in the overridden method.
This class has both a default constructor and one that can take a data
object. This can be handy when using it as an extending anonymous inner
class when you need to use variables inside the inner class that are
cumbersome to change to final in the enclosing class.
