Line 83:

In C++, [[C++11#Rvalue references and move constructors|move constructors]] take a value reference to an object of the class, and are used to implement ownership transfer of the parameter object's resources.

== Syntax for move constructor ==

* [[Java (programming language)|Java]], [[C++]], [[C Sharp (programming language)|C#]], [[ActionScript]], and {{nowrap|[[PHP]] 4}} have a naming convention in which constructors have the same name as the class of which they are associated with.

Line 93:

* [[Object Pascal]] constructors are signified by the keyword "<code>constructor</code>" and can have user-defined names (but are mostly called "<code>Create</code>").

* In [[Objective-C]], the constructor method is split across two methods, "<code>alloc</code>" and "<code>init</code>" with the <code>alloc</code> method setting aside (allocating) memory for an instance of the class, and the <code>init</code> method handling the bulk of initializing the instance. A call to the method "<code>new</code>" invokes both the <code>alloc</code> and the <code>init</code> methods, for the class instance.
