| Public Member Functions | |
|---|---|
| TLinearOrder(TInt(*)(const T &, const T &)) | |
| operator TGeneralLinearOrder() | |
A templated class which packages a function that determines the order of two objects of a given class type. During binary search operations the search term is always passed as the first argument and the second argument is an element of the array being searched.
A TLinearOrder<T> object is constructed and passed as a parameter to member functions of the array classes RArray<T> and RPointerArray<T>.
See also: RArray RPointerArray
Constructs the object taking the specified function as an argument.
The specified function should implement an algorithm that determines the order of two class T type objects. It should return:
1. zero, if the two objects are equal.
2. a negative value, if the first object is less than the second.
3. a positive value, if the first object is greater than the second.
| Parameter | Description |
|---|---|
| anOrder | A pointer to a function that takes constant references to two class T objects and returns a TInt value. |
