Type Parameters:

V - the value type stored in the map.

All Superinterfaces:

Map<Long,V>

public interface LongObjectMap<V>
extends Map<Long,V>

Interface for a primitive map that uses longs as keys.

Method Detail

get

V get(long key)

Gets the value in the map with the specified key.

Parameters:

key - the key whose associated value is to be returned.

Returns:

the value or null if the key was not found in the map.

put

V put(long key,
      V value)

Puts the given entry into the map.

Parameters:

key - the key of the entry.

value - the value of the entry.

Returns:

the previous value for this key or null if there was no previous mapping.

remove

V remove(long key)

Removes the entry with the specified key.

Parameters:

key - the key for the entry to be removed from this map.

Returns:

the previous value for the key, or null if there was no mapping.

entries

Iterable<LongObjectMap.PrimitiveEntry<V>> entries()

Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, the LongObjectMap.PrimitiveEntrys returned by the Iterator may change as the Iterator progresses. The caller should not rely on LongObjectMap.PrimitiveEntry key/value stability.

containsKey

boolean containsKey(long key)

Indicates whether or not this map contains a value for the specified key.
