Description 

 

class function EnsureInitialized<T: class, constructor>(var pVar: T): Boolean; overload; static; 

If pVar is nil, an instance of T is created and assigned to pVar. This is done in a threadsafe way.  

 

class function EnsureInitialized<T: IInterface>(var pIntf: T; pFactoryMethod: TFunc<T>): Boolean; overload; static; 

If pIntf is nil, an instance is created by calling pFactoryMethod and assigned to pVar. This is done in a threadsafe way.  

 

class procedure IntfAssign<T:IInterface>(var pIntf: T; const pValue: T); overload; static; 

Assigns an interface to a variable and releases the previous interface (if assigned) in an atomic and so threadsafe operation.  

 

class function IntfAssignIfEmpty<T:IInterface>(var pIntf; const pValue: T): Boolean; overload; static; 

Assigns an interface to a variable, but only if this was empty, in an atomic and so threadsafe operation.  

 

class procedure IntfClear<T:IInterface>(var pIntf: T); overload; static; 

Releases an interface in an atomic and so threadsafe operation  

 

class function IntfExchange<T:IInterface>(var pIntf; const pValue: T): T; static; 

Assigns an interface to a variable and returns the previous interface (if assigned) in an atomic and so threadsafe operation  

 

class function SetEqualOrHigher(var pVar: UInt64; const pNewValue: UInt64): Boolean; static; 

Assigns pNewValue to pVar in an atomic operation if the new value is higher than the current one.
