static Revision::newKnownCurrent ( IDatabase  $db,

)
static

Load a revision based on a known page ID and current revision ID from the DB.

This method allows for the use of caching, though accessing anything that normally requires permission checks (aside from the text) will trigger a small DB lookup. The title will also be lazy loaded, though setTitle() can be used to preload it.

Parameters
IDatabase$db
int$pageIdPage ID
int$revIdKnown current revision of this page
Returns
Revision|bool Returns false if missing
