Comparison C Sequence Functions

The following comparison C functions take two input sequences, left and right, and produce the boolean result sequence result .

If the two input sequence arguments are of different lengths the operation will be performed on only the number of elements in the shorter of the two sequences.

The function signatures are of the following form:

 
    MCO_RET mco_seq_operator_TYPE(mco_seq_iterator_h result, 
            mco_seq_iterator_h left, 
            mco_seq_iterator_h right); 
             

where TYPE is one of the types listed in the Analytics Functions page and operator is one of the following:

mco_seq_eq_TYPE()	The element of the result sequence is true for corresponding elements that are equal in the left and right sequences; otherwise false
mco_seq_ne_TYPE()	The element of the result sequence is true for corresponding elements that are not equal in the left and right sequences; otherwise false
mco_seq_gt_TYPE()	The element of the result sequence is true for corresponding elements where the left element is greater than the right; otherwise false
mco_seq_ge_TYPE()	The element of the result sequence is true for corresponding elements where the left element is greater than or equal to the right; otherwise false
mco_seq_lt_TYPE()	The element of the result sequence is true for corresponding elements where the left element is less than the right; otherwise false
mco_seq_le_TYPE()	The element of the result sequence is true for corresponding elements where the left element is less than or equal to the right; otherwise false

Example

Following is an example code snippet demonstrating a comparison operator function:

         
    {
        mco_trans_h trans;
        mco_cursor_t quote_cursor;
        Quote quote;
        mco_seq_iterator_t high_iterator, low_iterator, result_iterator;
        MCO_RET rc;
        ...
         
        for (rc = mco_cursor_first(trans, &quote_cursor); 
            rc != MCO_S_CURSOR_END; 
            rc = mco_cursor_next(trans, &quote_cursor)) 
        {
            Quote_from_cursor(trans, &quote_cursor, &quote);
            Quote_high_iterator(&quote, &high_iterator);
            Quote_low_iterator(&quote, &low_iterator);
            ...
            rc = mco_seq_eq_float(&result_iterator, &low_iterator, &high_iterator);
            
            ...
        }
        ...
    }
