Method Summary public  BooleanExpression and(ScalarExpression expr)      public  BooleanExpression not()      Constructor Detail ExistsExpression public ExistsExpression(QueryExpression qs, QueryExpression argumentExpression)(Code) Constructs a expression for existence of the argument expression. Parameters:   qs - the QueryExpression Parameters:   argumentExpression - the QueryExpression returning records to the exists function ExistsExpression public ExistsExpression(QueryExpression qs, QueryExpression argumentExpression, boolean truthTest)(Code) Constructs a expression for existence (or not) of the argument expression. Create an "EXISTS", or "NOT EXISTS" depending on the truth flag. Parameters:   qs - the QueryExpression Parameters:   argumentExpression - the QueryExpression returning records to the exists function Parameters:   truthTest - true to perform a "exists", and false to perform a "not exists" Method Detail and public BooleanExpression and(ScalarExpression expr)(Code) not public BooleanExpression not()(Code) Methods inherited from
