dereference<T>


Category: functors	Component type: type

Description

dereference<T> is a function object. Specifically, it is an Adaptable Unary Function, which means it is a function object that promotes a pointer to a reference. If f is a pointer to an object of class dereference<T> and x is a pointer to an object of class T, then f(x) returns *x.

Example

Definition

Defined in functors.hpp.

Template parameters

Parameter	Description	Default
`T`	The type of `dereference`'s arguments.

Model of

Adaptable Unary Function, DefaultConstructible

Type requirements

T has an operator*(). std::iterator_traits<> has been specialized for T.

Public base classes

unary_function<T,std::iterator_traits<T>::reference>.

Members

Member	Where defined	Description
`argument_type`	Adaptable Unary Function	The type of the tmplate argument: `T`
`result_type`	Adaptable Unary Function	The type of the result: `std::iterator_traits<T>::reference`
`dereference()`	DefaultConstructible	The default constructor.
`bool operator()(const T& x)`	Unary Function	Function call operator. The return value is `T::operator*(x)`.

New members

All of dereference's members are defined in the Adaptable Unary Function and DefaultConstructible requirements. dereference does not introduce any new members.
