Method Compare

Your_Class::Compare

By default, the "Compare()" method does a string compare on the content of the "Sort" string. You set the value of this string with the method "Sort_Set()", usually within the constructor. However, if you want to use another technique to compare 2 instance of the same class, you can override this method.

Syntax

int Your_Class::Compare(

SliceO_Class *pt_b

)

Parameters

pt_b

Pointer to the class we want to compare this class to.

Return value

This method return an integer value:

·< 0 if if "this" is to be placed before "pt_b",

·> 0 if this is to be placed after "pt_b",

·= 0 if both are equivalent.
