Base class for intrusive reference counting.

Embeds the refcount in the object itself - no separate control block allocation, no atomic operations. Safe for single-threaded libuv loops.

Usage: inherit from RefCounted, then use IntrusivePtr instead of std::shared_ptr.

Public Methods

Return	Name	Description
	`RefCounted`	Defaulted constructor.
	`RefCounted` `inline`
`void`	`addRef` `const` `inline`	Increments the reference count. Called by IntrusivePtr on acquisition.
`bool`	`releaseRef` `const` `inline`	Decrements the reference count.
`int`	`refCount` `const` `inline`	Returns the current reference count.

RefCounted

RefCounted() = default

Defaulted constructor.

RefCounted

inline

inline RefCounted(const RefCounted &) noexcept

addRef

const inline

inline void addRef() const noexcept

Increments the reference count. Called by IntrusivePtr on acquisition.

releaseRef

const inline

inline bool releaseRef() const noexcept

Decrements the reference count.

Returns

true if the count reached zero (caller should delete the object).

refCount

const inline

inline int refCount() const noexcept

Returns the current reference count.

Returns

Current reference count.
