omni::str::ReadOnlyCString

Defined in omni/str/IReadOnlyCString.h

class ReadOnlyCString : public omni::core::Implements<omni::str::IReadOnlyCString>

Concrete implementation of the IReadOnlyCString interface.

Public Functions

inline void acquire() noexcept

See omni::core::IObject::acquire.

inline void release() noexcept

See omni::core::IObject::release.

inline void *cast(omni::core::TypeId id) noexcept

See omni::core::IObject::cast.

Public Static Functions

static inline omni::core::ObjectPtr<IReadOnlyCString> create(const char *str)

Creates a read-only string. The given string is copied and must not be nullptr.

Protected Functions

inline virtual void acquire_abi() noexcept override

Increments the object’s reference count.

Objects may have multiple reference counts (e.g. one per interface implemented). As such, it is important that you call omni::core::IObject::release() on the same pointer from which you called omni::core::IObject::acquire().

Do not directly use this method, rather use omni::core::ObjectPtr, which will manage calling omni::core::IObject::acquire() and omni::core::IObject::release() for you.

Thread Safety

This method is thread safe.

inline virtual void release_abi() noexcept override

Decrements the objects reference count.

Most implementations will destroy the object if the reference count reaches 0 (though this is not a requirement).

Objects may have multiple reference counts (e.g. one per interface implemented). As such, it is important that you call omni::core::IObject::release() on the same pointer from which you called omni::core::IObject::acquire().

Do not directly use this method, rather use omni::core::ObjectPtr, which will manage calling omni::core::IObject::acquire() and omni::core::IObject::release() for you.

Thread Safety

This method is thread safe.

inline virtual void *cast_abi(TypeId id) noexcept override

Returns a pointer to the interface defined by the given type id if this object implements the type id’s interface.

Objects can support multiple interfaces, even interfaces that are in different inheritance chains.

The returned object will have omni::core::IObject::acquire() called on it before it is returned, meaning it is up to the caller to call omni::core::IObject::release() on the returned pointer.

The returned pointer can be safely reinterpret_cast<> to the type id’s C++ class. For example, “omni.windowing.IWindow” can be cast to omni::windowing::IWindow.

Do not directly use this method, rather use a wrapper function like omni::core::cast() or omni::core::ObjectPtr::as().

Thread Safety

This method is thread safe.

Protected Attributes

std::atomic<uint32_t> m_refCount
