[TYPO3-dev] Determine if ext_tables is cached

[Philipp]

Hi

i wrote i function that merges flexforms for plugins, background is, that i have many plugins using the same fields (because working with same base-models etc). So i wrote a service, that merges flexforms (i only have to write the additions to the new flexform, everything else is inherited). Now i realized that the cached ext_tables.php does all of this live request by request. So i wonder if i can determine the ext_tables mode.

Is there a constant or mode defined that i could request? When the cache is empty and the ext_tables is being generated i want the function to parse, else just return the cached XML file....

Or how can i use the cachingframework for this purpose (i did not work with the caching framework so far), so it deletes my cache-files on clear configuration cache.
