Logical C++ Sequence Methods

The following logical C++ Sequence operators (except the not operator "!") take a single argument other, and perform the indicated logical operation oo the object's sequence elements as the left operand and the other sequence elements as the right operand. They return a Boolean result Sequence (specifically of type mco_seq_bool).

The function signatures are of the following two forms (where op is the indicated operation):

 
    Sequence<mco_seq_bool> operator !() const;
             

or

 
    Sequence<mco_seq_bool> operator op(Sequence<mco_seq_bool> const& other) const;
             

where operator is one of the following:

Sequence<mco_seq_bool> operator !() const	The element of the result sequence is the logical not of the corresponding element in the object's sequence
Sequence<mco_seq_bool> operator &&(Sequence<mco_seq_bool> const& other) const	The element of the result sequence is the logical and of the corresponding elements in left and right
Sequence<mco_seq_bool> operator ||(Sequence<mco_seq_bool> const& other) const	The element of the result sequence is the logical or of the corresponding elements in left and right
Sequence<mco_seq_bool> operator ^(Sequence<mco_seq_bool> const& other) const	The element of the result sequence is the logical exclusive or of the corresponding elements in left and right

Example

Following is an example code snippet demonstrating logical operators :

         
    {
        ...
        Sequence<float> high = quote.high_iterator();
        Sequence<float> low = quote.low_iterator();
        Sequence<mco_seq_bool> equal = high == low;
        Sequence<mco_seq_bool> ne = !equal;
        equal.reset();
        Sequence<mco_seq_bool> allTrue = ne || equal;
        ...
    }
