Ref

Reference counting support.

Implemented for case when T is RefCountedObject. Similar to shared_ptr in C++. Allows to share object, destroying it when no more references left.

Useful for automatic destroy of objects.

struct Ref (

T

) {

bool isNull [@property getter];

int refCount [@property getter];

Ref opAssign(Ref data);

Ref opAssign(Ref data);

Ref opAssign(T data);

void clear();

T get [@property getter];

const(T) get [@property getter];

}

Constructors

this this(T data): init from T

Destructor

~this ~this(): decreases counter, and destroys object if no more references left

Postblit

this(this) this(this): after blit

Alias This

Members

Functions

clear void clear(): clears reference
opAssign Ref opAssign(Ref data): assign from another refcount by reference
opAssign Ref opAssign(Ref data): assign from another refcount by value
opAssign Ref opAssign(T data): assign object

Properties

get T get [@property getter]: returns object reference (null if not assigned)
get const(T) get [@property getter]: returns const reference from const object
isNull bool isNull [@property getter]: returns true if object is not assigned
refCount int refCount [@property getter]: returns counter of references
