function node_access_rebuild

You are here

7 node.module node_access_rebuild($batch_mode = FALSE)
5 node.module node_access_rebuild()
6 node.module node_access_rebuild($batch_mode = FALSE)
8 node.module node_access_rebuild($batch_mode = FALSE)

Rebuilds the node access database.

This is occasionally needed by modules that make system-wide changes to access levels. When the rebuild is required by an admin-triggered action (e.g module settings form), calling node_access_needs_rebuild(TRUE) instead of node_access_rebuild() lets the user perform his changes and actually rebuild only once he is done.

Note: As of Drupal 6, node access modules are not required to (and actually should not) call node_access_rebuild() in hook_enable/disable anymore.

Parameters

$batch_mode: Set to TRUE to process in 'batch' mode, spawning processing over several HTTP requests (thus avoiding the risk of PHP timeout if the site has a large number of nodes). hook_update_N and any form submit handler are safe contexts to use the 'batch mode'. Less decidable cases (such as calls from hook_user, hook_taxonomy, etc...) might consider using the non-batch mode.

is there any function to rebuild ENTITY_ACCESS_REBUILD?
