Detailed Description

Move, copy, and destruction operations.

Special member functions controlling MagicPrivate lifetime and resource ownership transfer.

Function Documentation

MagicPrivate() [1/2]

Recognition::Magic::MagicPrivate::MagicPrivate ( const MagicPrivate & )

delete

Deleted copy constructor.

MagicPrivate cannot be copied because each instance owns a unique libmagic cookie handle. Use move semantics instead.

See also

Magic::Magic(const Magic&)

MagicPrivate() [2/2]

Recognition::Magic::MagicPrivate::MagicPrivate ( MagicPrivate && )

defaultnoexcept

Move constructor.

Transfers ownership of all resources from the source instance. After the move, the source is left in the Closed state (m_cookie = nullptr).

Note

The moved-from object is safe to destroy or reassign.

Magic::Magic(Magic&&)

operator=() [1/2]

MagicPrivate & Recognition::Magic::MagicPrivate::operator= ( const MagicPrivate & )

delete

Deleted copy assignment operator.

MagicPrivate cannot be copied because each instance owns a unique libmagic cookie handle. Use move semantics instead.

Magic::operator=(const Magic&)

operator=() [2/2]

MagicPrivate & Recognition::Magic::MagicPrivate::operator= ( MagicPrivate && )

defaultnoexcept

Move assignment operator.

Releases any existing resources, then transfers ownership from the source instance. After the move, the source is left in the Closed state.

Returns

Reference to this instance.

See also

Magic::operator=(Magic&&)

~MagicPrivate()

Recognition::Magic::MagicPrivate::~MagicPrivate ( )

default

Destructor.

Automatically releases the libmagic cookie via CookieT's custom deleter (calls magic_close()).

Resource Release

The CookieT unique_ptr ensures Detail::magic_close() is called when the instance is destroyed, preventing resource leaks.
