Inheritance diagram for Id:

Detailed Description

Id represents an identifier consisting of a c-string. Such identifiers are used mainly to identify entities such as interfaces, components, classes, registries, entries, modules or published objects.

Constructor & Destructor Documentation

Id() [1/6]

constexpr Id ( )

constexpr

Constructs a null Id. The internal c-string will be nullptr.

Id() [2/6]

Id ( const volatile Char *  str )

explicit

Constructs an Id for a given c-string. str is used directly for the internal c-string pointer. It is assumed that the c-string exists at least as long as the constructed Id.

Parameters

[in]

str

Identifier as c-string, may be nullptr. This will always be used directly, i.e., no copy is made.

Id() [3/6]

constexpr Id ( const Char(&)  str[N] )

explicitconstexpr

Id() [4/6]

Id

(

Id &&

other

)

Constructs an Id by moving the values from another Id.

Parameters

[in]

other

Another Id to move from.

Id() [5/6]

Id

(

const Id &

other

)

Copy constructs an Id from another Id.

Parameters

[in]

other

Another Id to copy from.

~Id()

~Id

(

)

Destructs the Id. If the Id uses a RefCountedCString, the reference will be removed.

Id() [6/6]

Id ( const CString &  )

explicitprivatedelete

Member Function Documentation

NullValue()

static const Id& NullValue ( )

static

Reset()

void Reset

(

)

Resets the Id. Afterwards, its internal c-string will be nullptr.

MAXON_OPERATOR_MOVE_ASSIGNMENT()

operator=()

Id& operator=

(

const Id &

other

)

Init() [1/6]

ResultMem Init	(	const Char *	str,
		Bool	copyString
	)

Sets this Id to a new value. If copyString is false, str is used directly for the internal c-string pointer, and it is assumed that the c-string exists at least as long as this Id. Otherwise, if copyString is true, a RefCountedCString is created for str and used for the internal c-string.

Parameters

[in]	str	Identifier as c-string, may be nullptr.
[in]	copyString	If true, a copy of str is made at first (as a RefCountedCString).

Returns

False if a copy had to be made, but the allocation failed. True otherwise.

Init() [2/6]

ResultMem Init

(

const Block< const Char > &

str

)

Sets this Id to str. A RefCountedCString is created for str and used for the internal c-string.

Parameters

[in]

str

Identifier as a block of characters (no null termination required).

Returns

False if the allocation for the RefCountedCString failed. True otherwise.

Init() [3/6]

ResultMem Init

(

const CString &

str

)

Sets this Id to str. A RefCountedCString is created for str and used for the internal c-string.

Parameters

[in]

str

Identifier as CString.

Returns

False if the allocation for the RefCountedCString failed. True otherwise.

Init() [4/6]

ResultMem Init

(

const String &

str

)

Sets this Id to str.

Parameters

[in]

str

Identifier as String.

Returns

False if the allocation failed. True otherwise.

Init() [5/6]

void Init

(

const InternedId &

id

)

Sets this Id to id.

Parameters

[in]

id

Interned Id.

Init() [6/6]

void Init

(

const RefCountedCString *

str

)

Sets this Id to a RefCountedCString.

Parameters

[in]

str

Identifier as RefCountedCString.
