Template:cpp/concept/title Template:cpp/concept/navbar
Specifies that an instance of the type can be copy-constructed (copied).
This concept implies Template:concept.
Requirements
The type must implement the following functions:
Type::Type
| Type::Type( Type& other ); Type::Type( const Type& other ); |
(One of the variants is sufficient) | |
Copy constructor: constructs an instance of a type with the contents of other. The internal state of other is not modified.
The following expressions must have the specified effects:
| Expression | Effects |
| Type a = v; | a is equivalent to v, where rv is an instance of Type. v must be unchanged.
|
| Type(v); | a temporary object of type Type is equivalent to v, where v is an instance of Type. v must be unchanged.
