Parameters

$entity_type: Type entity.

$id: Identifier within the type.

$tag: The VotingAPI tag string.

$uid: The user ID trying to cast the vote.

Return value

bool|NULL Returns TRUE if voting is supported on this object. Returns NULL if voting is not supported on this object by this module. If needing to absolutely deny all voting on this object, regardless of permissions defined in other modules, return FALSE. Note if all modules return NULL, stating no preference, then access will be denied.
