Member Function Documentation

template<typename T>

void* tervel::containers::wf::vector::PopOpSubHelper< T >::complete	(	void *	current,
		std::atomic< void * > *	address
	)

inlinevirtual

This method is implemented by each sub class and must guarantee that upon return that the descriptor no longer exists at the address it was placed.

Parameters

current	the reference to this object as it is at the address,
address	the location this object was read from

Implements tervel::util::Descriptor.

template<typename T>

void* tervel::containers::wf::vector::PopOpSubHelper< T >::get_logical_value ( )

inlinevirtual

This method is implemented by each sub class.

It returns the logical value of the past address. If the associated operation is still in progress then it will generally return the value that was replaced by this descriptor. Otherwise it will generally return the result of the operation for the specified address.

It can only be called from the static function which protects the object from being reused during the function.

Implements tervel::util::Descriptor.

template<typename T>

bool tervel::containers::wf::vector::PopOpSubHelper< T >::on_watch	(	std::atomic< void * > *	,
		void *
	)

inlinevirtual

This method is optional to implement for each sub class.

In the event there is a complex dependency between descriptor objects, where watching one implies performing other actions, such as watching a parent object, a developer will implement this function to encapsulate that logic

This function is called by the static watch function It should not watch itself.

Parameters
