Core link handler
The Core link handler, implementing the
\TYPO3\ described here
matches between different internal representations of a link. It is not
to be mixed up with the backend link handler, commonly
also just called link handler. The latter implements the
\TYPO3\ and renders a
tab in the link browser.
You can find the built-in Core link handlers in
EXT:.
In the tutorial section we provide an example on how to implement a custom Core link handler.
