getMap

protected MutableMap<K,C> getMap()

Specified by:

getMap in class AbstractMultimap<K, V, C extends MutableCollection<V>>

size

This method is provided to allow for subclasses to provide the behavior. It should add the specified amount to the value that is returned by calling size().

subtractFromTotalSize

protected void subtractFromTotalSize(int value)

This method is provided to allow for subclasses to provide the behavior. It should subtract the specified amount from the value that is returned by calling size().

clearTotalSize

protected void clearTotalSize()

This method is provided to allow for subclasses to provide the behavior. It should set the value returned by size() to 0.
