Detailed Description

Each TypoScript snippet is turned by the tokenizers into a stream of lines. Tokenizers return instances of this class.

Iterate line streams in a foreach loop using getNextLine().

: Internal tokenizer structure.

Member Function Documentation

◆ __serialize()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::__serialize ( )

final

When storing to cache, we only store FE relevant properties and skip irrelevant things. In particular, $currentIndex should always initialize to -1 and does not need to be stored.

◆ __toString()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::__toString ( )

Create a source string from given token lines. This is used in backend to turn the "full" token streams of lines into strings for output.

◆ append()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::append ( LineInterface $line )

Stream creation.

Definition at line 67 of file LineStream.php.

◆ getNext()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::getNext ( )

Get next line and raise pointer.

Methods getNext(), peekNext() and reset() are an alternative to getNextLine() which allow peek of the next line, which getNextLine() does not. The disadvantage is that these methods create internal state in $this->currentIndex, which getNextLine() does not. Use getNext() iteration only if peekNext() is needed to avoid creating useless state.

◆ getNextLine()

iterable<LineInterface> TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::getNextLine ( )

Returns: ‪iterable<LineInterface>

◆ isEmpty()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::isEmpty ( )

We sometimes create a line stream but don't add lines. This method returns true if lines have been added.

Definition at line 77 of file LineStream.php.

◆ peekNext()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::peekNext ( )

Get next line but do not raise pointer.

◆ reset()

TYPO3\CMS\Core\TypoScript\Tokenizer\Line\LineStream::reset ( )

Reset current pointer. Typically, call this before iterating with getNext().
