Method Details

getAndResetContainment

public it.unimi.dsi.fastutil.longs.LongSet getAndResetContainment(T listener)

First, uses the reverse lookup map to remove listener from all sets in the lookup map.
Then, clears the listeners containment set.

Parameters:

listener - The listener to clean up.

Returns:

An empty set that should be populated with the chunks/sections the listener is contained in.
