Not Getting Sure About "EOnlineComparisonOp"

[DevDas]

namespace EOnlineComparisonOp
{
    enum Type
    {
        Equals,
        NotEquals,
        GreaterThan,
        GreaterThanEquals,
        LessThan,
        LessThanEquals,
        Near,
        In,
        NotIn,
    }
}

I Don’t Understand To whom shall I compare ??
Also I Searched API For this , There Are Nothing In Details.

You Said In The Video At 7:08 -

“Should It Equal To Presence , Should It Greater Than Two Players Or Less Than”

What Do You mean By That ? Can You Please Explain ??
Please?

That’s just an enum so you can tell the function how you want to compare.
Basic example

enum class Comparison
{
    Less,
    Equal,
    Greater
};

bool Compare(int A, int B, Comparison C)
{
    switch (C)
    {
    case Comparison::Less:
        return A < B;
    case Comparison::Equal:
        return A == B;
    case Comparison::Greater:
        return A > B;
    }
}
int main()
{
    bool Example = Compare(1, 2, Comparison::Less);
}

And I assume this code was written before scoped enums (enum class) existed which is why namespace Foo { enum Bar {}; } is used, it achieves almost the same thing.

Note: I have no knowledge about that section and am not the TA for this course.

Ok Now I Understand How The Comparison Takes Place

But Can You Tell Me What The Two Things Are Comparing Here?
Like In Your Code Its A & B But Whats in The EOnlineComparisonOp ??

Based on the name FOnlineSearchSetting::Set<bool> is a set, so you’re comparing the first argument to the key and if it’s found, setting it to the second argument.
