Methods in com.mckoi.database with parameters of type Operator

Modifier and Type	Method	Description
void	Expression.addOperator(Operator op)	Adds a new operator into the expression.
Table	Table.all(QueryContext context, Expression lhs, Operator op, Table table)	Evaluates a non-correlated ALL type operator given the LHS expression, the RHS subquery and the ALL operator to use.
boolean	Table.allColumnMatchesValue(int column, Operator op, TObject ob)	Returns true if the given column contains all values that the given operator returns true for with the given value.
Table	Table.any(QueryContext context, Expression lhs, Operator op, Table right_table)	Evaluates a non-correlated ANY type operator given the LHS expression, the RHS subquery and the ANY operator to use.
