Method Detail
-
get
public java.lang.Object get(int key)
Description copied from interface:IntObjectMap
Gets the value in the map with the specified key.- Specified by:
get
in interfaceIntObjectMap<java.lang.Object>
- 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
public java.lang.Object put(int key, java.lang.Object value)
Description copied from interface:IntObjectMap
Puts the given entry into the map.- Specified by:
put
in interfaceIntObjectMap<java.lang.Object>
- 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
public java.lang.Object remove(int key)
Description copied from interface:IntObjectMap
Removes the entry with the specified key.- Specified by:
remove
in interfaceIntObjectMap<java.lang.Object>
- 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
public java.lang.Iterable<IntObjectMap.PrimitiveEntry<java.lang.Object>> entries()
Description copied from interface:IntObjectMap
Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, theIntObjectMap.PrimitiveEntry
s returned by theIterator
may change as theIterator
progresses. The caller should not rely onIntObjectMap.PrimitiveEntry
