TIdentityRelation Class Reference

class TIdentityRelation

A templated class which packages a function that determines whether two objects of a given class type match. During linear 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 TIdentityRelation<T> object is constructed and passed as a parameter to member functions of the array classes RArray<T> and RPointerArray<T>.

Constructor & Destructor Documentation

TIdentityRelation()

TIdentityRelation()[inline]

Constructs the object to use the equality operator (==) defined for class T to determine whether two class T type objects match.

TIdentityRelation(TBool(*)(const T &, const T &))

TIdentityRelation(TBool(*)(const T &, const T &)anIdentity)[inline]

Constructs the object taking the specified function as an argument.

The specified function should implement an algorithm for determining whether two class T type objects match. It should return:

1. true, if the two objects match.

2. false, if the two objects do not match.

Parameters

TBool(*)(const T &, const T &) anIdentityA pointer to a function that takes constant references to two class T objects and returns a TInt value.

Member Functions Documentation

EqualityOperatorCompare(const T &, const T &)

TBool EqualityOperatorCompare(const T &aLeft,
const T &aRight
)[private, static, inline]

Compares two objects of class T using the equality operator defined for class T.

Parameters

const T & aLeft
const T & aRight

operator TGeneralIdentityRelation()

operator TGeneralIdentityRelation()const [inline]

Operator that gets the function that determines whether two objects of a given class type match.
