class Link

Defined in: TSLink.h

The Link class template encapsulates a smart pointer to an object.

Definition

template <class type> class Link : public ListElement<Link<type>>

Member Functions

Link::GetTarget Returns the target to which a link points.

Template Parameters

type The type of object to which the link may point.

Constructor

Link();

explicit Link(type *target);

Parameters

target The object to which the link initially points.

Description

The Link class template provides a mechanism through which a smart pointer to an object of the type given by the type template parameter can be stored. The link to an object is automatically reset to nullptr if the target object is destroyed. A class of type T to which a link can be established must inherit from the class LinkTarget<T>. The LinkTarget class template stores a list of all links that currently point to it. When the link target is destroyed, all of the links in the list are cleared.

Overloaded Operators

`operator type *(void) const;`	A `Link` object can be implicitly converted to a pointer to the object to which it points.
`type *operator ->(void) const;`	Dereferencing a `Link` object is equivalent to dereferencing the pointer that it holds.
`void operator =(type *target);`	Sets the pointer that the `Link` object stores.

Base Classes

ListElement<Link<type>> The set of links to an object are stored in a list by the LinkTarget class.
