Method Detail

cacheOrGet

V cacheOrGet(int key,
             V value)

Returns:

written value

remove

boolean remove(int key,
               V value)

replace

boolean replace(int key,
                V oldValue,
                V newValue)

elements

java.util.Enumeration<V> elements()

size

int size()

Specified by:

size in interface IntObjectMap<V>

Returns:

Approximate number of elements in the map. The usage is discouraged since First, in concurrent context it doesn't have much sense and Second, for weak- or soft- keyed maps it returns the total number of references rather than alive values because otherwise it would be too expensive

putIfAbsent

V putIfAbsent(int key,
              V value)

Returns:

the previous value associated with the specified key, or null if there was no mapping for the key
