| class TIdentityRelation |
| Public Member Functions | |
|---|---|
| TIdentityRelation() | |
| TIdentityRelation(TBool(*)(const T &, const T &)) | |
| operator TGeneralIdentityRelation() | |
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>.

| 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 &) | 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 | |
|---|---|
| anIdentity | A pointer to a function that takes constant references to two class T objects and returns a TInt value. |
