# Content objects {#content-objects}

The extension registers the following custom content objects (`HBS_*`). They
are only useful inside a `process-form` data processor block; using them
elsewhere may log a warning and return an empty string.

Every `HBS_*` content object supports the standard [stdWrap](https://docs.typo3.org/m/typo3/reference-typoscript/main/en-us/Functions/Stdwrap.html#stdwrap)
sub-key. The value resolved by the content object is passed through `stdWrap`
before being stored in the processed data array.

The table below lists all content objects, roughly ordered from the ones needed in
almost every form to more specialised ones.
