public boolean checkOperandTypes(SqlCallBinding callBinding,
                                 boolean throwOnFailure)
Description copied from class: SqlOperator
Checks that the operand values in a SqlCall to this operator are valid. Subclasses must either override this method or supply an instance of SqlOperandTypeChecker to the constructor.

checkOperandTypes in class SqlOperator
callBinding - description of call
throwOnFailure - whether to throw an exception if check fails (otherwise returns false in that case)
whether check succeeded


public SqlOperandCountRange getOperandCountRange()
Description copied from class: SqlOperator
Returns a constraint on the number of operands expected by this operator. Subclasses may override this method; when they don't, the range is derived from the SqlOperandTypeChecker associated with this operator.
