get
public V get(byte key)
Description copied from interface:ByteObjectMap
Gets the value in the map with the specified key.- Specified by:
get
in interfaceByteObjectMap<V>
- 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 V put(byte key, V value)
Description copied from interface:ByteObjectMap
Puts the given entry into the map.- Specified by:
put
in interfaceByteObjectMap<V>
- 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 V remove(byte key)
Description copied from interface:ByteObjectMap
Removes the entry with the specified key.- Specified by:
remove
in interfaceByteObjectMap<V>
- 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.
-
size
public int size()
- Specified by:
size
in interfacejava.util.Map<java.lang.Byte,V>
-
isEmpty
public boolean isEmpty()
- Specified by:
isEmpty
in interfacejava.util.Map<java.lang.Byte,V>
-
clear
public void clear()
- Specified by:
clear
in interfacejava.util.Map<java.lang.Byte,V>
-
containsKey
public boolean containsKey(byte key)
Description copied from interface:ByteObjectMap
Indicates whether or not this map contains a value for the specified key.- Specified by:
containsKey
in interfaceByteObjectMap<V>
-
containsValue
public boolean containsValue(java.lang.Object value)
- Specified by:
containsValue
in interfacejava.util.Map<java.lang.Byte,V>
-
containsKey
public boolean containsKey(java.lang.Object key)
- Specified by:
containsKey
in interfacejava.util.Map<java.lang.Byte,V>
-
get
public V get(java.lang.Object key)

entries
public java.lang.Iterable<ByteObjectMap.PrimitiveEntry<V>> entries()
Description copied from interface:ByteObjectMap
Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, theByteObjectMap.PrimitiveEntry
s returned by theIterator
may change as theIterator
progresses. The caller should not rely onByteObjectMap.PrimitiveEntry
key/value stability.- Specified by:
entries
in interfaceByteObjectMap<V>

public java.util.Set<java.lang.Byte> keySet()
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Byte,V>
-
entrySet
public java.util.Set<java.util.Map.Entry<java.lang.Byte,V>> entrySet()
- Specified by:
entrySet
in interfacejava.util.Map<java.lang.Byte,V>
