Constructors

this this(): Constructs an IdTable object.

Members

Functions

genAnonClassID Identifier* genAnonClassID(): Generates an identifier for an anonymous class.
genAnonEnumID Identifier* genAnonEnumID(): Generates an identifier for an anonymous enum.
genAnonStructID Identifier* genAnonStructID(): Generates an identifier for an anonymous struct.
genAnonUnionID Identifier* genAnonUnionID(): Generates an identifier for an anonymous union.
genAnonymousID Identifier* genAnonymousID(cstring prefix): Generates an anonymous identifier.
genModuleID Identifier* genModuleID(): Generates an identifier for a module which has got no valid name.
inStatic Identifier* inStatic(hash_t idHash): Looks up the hash of an id in the static table.
inStatic Identifier* inStatic(cstring idString): Looks up idString in the static table.
isReservedIdentifier bool isReservedIdentifier(cstring str): Returns true if str is a keyword or a special token (__FILE__, __LINE__ etc.)
isThreadsafe bool isThreadsafe(): Returns true if access to the growing table is thread-safe.
isValidUnreservedIdentifier bool isValidUnreservedIdentifier(cstring str): Returns true if this is a valid identifier and if it's not reserved.
lookup Identifier* lookup(cstring idString): Looks up idString in both tables.
setThreadsafe void setThreadsafe(bool safe): Sets the thread safety mode of the growing table.

Static functions

isIdentifierString bool isIdentifierString(cstring str): Returns true if str is a valid D identifier.

Static variables

anonCount uint anonCount;: Counter for anonymous identifiers.
staticTable Identifier*[hash_t] staticTable;: A set of common, predefined identifiers for fast lookups.

Variables

growingTable Identifier*[hash_t] growingTable;: A table that grows with every newly found, unique identifier.
inGrowing LookupMethod inGrowing;: Looks up idString in the growing table.
