prepareExpressions

public void prepareExpressions(ExpressionPreparer preparer)
                        throws DatabaseException
Description copied from interface: StatementTreeObject
Prepares all expressions in this statement tree object by passing the ExpressionPreparer object to the 'prepare' method of the expression.

Specified by:
prepareExpressions in interface StatementTreeObject
