Detailed Description

A list of single identifier (!) tokens: TokenType::T_IDENTIFIER, and only of those.

This is used in TS lines that know certain parts have to be lists of identifier tokens only. For instance a LineIdentifierAssignment "foo.bar = barValue" return this stream for getIdentifierTokenStream(): The left side of an assignment line is a list of identifier tokens.

Identifiers can be "relative" on the right side for "<" (LineIdentifierCopy) and "=<" (LineIdentifierReference). Examples are "foo.bar < .baz" and "foo.bar =< .baz". These are identified by having a "." (dot) at the beginning on the right side. For these places, the toggle "relative" is set to true for the AST-builder to look for relative copy and copy-reference. The generic example are "relative" references in TS menus: 'RO < .NO'

For example, with "foo.bar < baz", the Tokenizer creates a LineIdentifierCopy line, having a TokenStreamIdentifier list of the T_IDENTIFIER tokens for 'foo' and 'bar' for getIdentifierTokenStream(), plus a TokenStreamIdentifier list of T_IDENTIFIER tokens for 'baz' for getValueTokenStream().

Note identifier streams on the left side (foo.bar = ...) are never relative, this toggle is true for "<" and "=<" only.

Lines that know they can only return TokenStreamIdentifier's - they are more specific than just TokenStream, are type-hinted as such. For instance getIdentifierTokenStream() type hints TokenStreamIdentifier.

◆ __toString()

TYPO3\CMS\Core\TypoScript\Tokenizer\Token\IdentifierTokenStream::__toString ( )

When rendering a source string from multiple identifiers, dots between single identifiers need to be added again. This is used in RootNode->toArray() to create that insane '< lib.whatever' as value when using the reference operator: "foo =< lib.whatever". See ContentObjectRenderer cObjGetSingle() and mergeTSRef().
