class Identifier: dmd.rootobject.RootObject;

nothrow this(const(char)* name);

Construct an identifier from the given name.

nothrow this(const(char)* name, size_t length, int value); nothrow @safe this(const(char)[] name, int value);

Construct an identifier from the given name.

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 generateId(const(char)[] prefix);

Generates a new identifier.

Parameters:

const(char)[] prefix this will be the prefix of the name of the identifier. For debugging purpose.

static nothrow Identifier generateAnonymousId(const(char)[] name);

Generates a new anonymous identifier.

Parameters:

const(char)[] name this will be part of the name of the identifier. For debugging purpose.

static nothrow Identifier generateId(const(char)[] prefix, size_t suffix); static nothrow Identifier generateId(const(char)* prefix, size_t length, size_t suffix);

Generates a new identifier.

Parameters:

const(char)[] `prefix`	this will be the prefix of the name of the identifier. For debugging purpose.
size_t `suffix`	this will be the suffix of the name of the identifier. This is what makes the identifier unique

static nothrow Identifier generateIdWithLoc(string prefix, const ref 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 void idPool(const(char)[] s, TOK value);

Used for inserting keywords into the string table.

Parameters:

const(char)[] `s`	string for keyword
TOK `value`	TOK.xxxx for the keyword

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

Determine if string is a valid Identifier.

Parameters:

const(char)* str string to check

Returns:

false for invalid
