	)

Parameters

NumHashBuckets	How many hash buckets are used for lookup by text (use 0 to disable text lookup)
IdChunkShift	2^IdChunkShift pointers are stored in a chunk for lookup by id (use 0 to disable id lookup)

Add()

TOptional< CSymbol > uLang::CSymbolTable::Add	(	const CUTF8StringView &	Text,
		bool	bIsGenerated = false
	)

Looks up a symbol by text, and if not present yet, adds it. Return empty optional if text is to long.

AddChecked()

CSymbol uLang::CSymbolTable::AddChecked	(	const CUTF8StringView &	Text,
		bool	bIsGenerated = false
	)

Looks up a symbol by text, and if not present yet, adds it. Asserts if text is to long.

Find()

TOptional< CSymbol > uLang::CSymbolTable::Find	(	const CUTF8StringView &	Text,
		bool	bIsGenerated = false
	)		const

Looks up a symbol by text.

Get()

ULANG_FORCEINLINE CSymbol uLang::CSymbolTable::Get

(

SymbolId

Id

)

const

Gets a symbol by id - id must exist.

ReAdd()

void uLang::CSymbolTable::ReAdd

(

CSymbol &

Symbol

)

Remaps a symbol from another symbol table to this symbol table I.e. symbol tables are merged by iterating through all symbols of one table and re-adding them to the other table
