get
public V get(char key)
Description copied from interface:CharObjectMapGets the value in the map with the specified key.- Specified by:
getin interfaceCharObjectMap<V>- Parameters:
key- the key whose associated value is to be returned.- Returns:
- the value or
nullif the key was not found in the map.
-
put
public V put(char key, V value)
Description copied from interface:CharObjectMapPuts the given entry into the map.- Specified by:
putin interfaceCharObjectMap<V>- Parameters:
key- the key of the entry.value- the value of the entry.- Returns:
- the previous value for this key or
nullif there was no previous mapping.
-
remove
public V remove(char key)
Description copied from interface:CharObjectMapRemoves the entry with the specified key.- Specified by:
removein interfaceCharObjectMap<V>- Parameters:
key- the key for the entry to be removed from this map.- Returns:
- the previous value for the key, or
nullif there was no mapping.
-
size
public int size()
- Specified by:
sizein interfacejava.util.Map<java.lang.Character,V>
-
isEmpty
public boolean isEmpty()
- Specified by:
isEmptyin interfacejava.util.Map<java.lang.Character,V>
-
clear
public void clear()
- Specified by:
clearin interfacejava.util.Map<java.lang.Character,V>
-
containsKey
public boolean containsKey(char key)
Description copied from interface:CharObjectMapIndicates whether or not this map contains a value for the specified key.- Specified by:
containsKeyin interfaceCharObjectMap<V>
-
containsValue
public boolean containsValue(java.lang.Object value)
- Specified by:
containsValuein interfacejava.util.Map<java.lang.Character,V>
-
containsKey
public boolean containsKey(java.lang.Object key)
- Specified by:
containsKeyin interfacejava.util.Map<java.lang.Character,V>

entries
public java.lang.Iterable<CharObjectMap.PrimitiveEntry<V>> entries()
Description copied from interface:CharObjectMapGets an iterable to traverse over the primitive entries contained in this map. As an optimization, theCharObjectMap.PrimitiveEntrys returned by theIteratormay change as theIteratorprogresses. The caller should not rely onCharObjectMap.PrimitiveEntrykey/value stability.- Specified by:
