class Identifier: dmd.root.rootobject.RootObject;

nothrow this(const(char)* name, size_t length, int value);

Construct an identifier from a D slice

Note

Since name needs to be \0 terminated for toChars, no slice overload is provided yet.

Parameters:

const(char)* name	the identifier name There must be '\0' at name[length].
size_t length	the length of name, excluding the terminating '\0'
int value	Identifier value (e.g. Id.unitTest) or TOK.identifier

static nothrow Identifier anonymous();

Sentinel for an anonymous identifier.

static nothrow Identifier generateIdWithLoc(string prefix, ref const Loc loc);

Generate deterministic named identifier based on a source location, such that the name is consistent across multiple compilations. A new unique name is generated. If the prefix+location is already in the stringtable, an extra suffix is added (starting the count at "1").

Parameters:

string prefix	first part of the identifier name.
Loc loc	source location to use in the identifier name.

Returns:

Identifier (inside Identifier.idPool) with deterministic name based on the source location.

static nothrow Identifier idPool(const(char)* s, uint len);

Create an identifier in the string table.

static nothrow bool isValidIdentifier(const(char)* str);

static nothrow bool isValidIdentifier(const(char)[] str);

Determine if string is a valid Identifier.

Parameters:

const(char)* str

string to check

Returns:

false for invalid
