Detailed Description

template<class T>
class TLinearOrder< T >

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>.

Constructor & Destructor Documentation

◆ TLinearOrder()

template<class T >

TLinearOrder< T >::TLinearOrder ( TInt(*)(const T &, const T &) anOrder )

inline

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:

zero, if the two objects are equal.
a negative value, if the first object is less than the second.
a positive value, if the first object is greater than the second.

Parameters

anOrder A pointer to a function that takes constant references to two class T objects and returns a TInt value.
