lookups

@accepts(RB.ExtDBKeyLookupCallback, gpointer)
@returns(none)
def lookups(callback, user_data)

Generates the set of possible lookup keys for @key and passes them to @callback in order. If the callback returns False, processing will stop.

This should only be used by the metadata store itself. Metadata providers and consumers shouldn't need to do this.

callback :

a callback to process lookup keys

user_data :

data to pass to @callback
