Type Parameters:

V - the value type stored in the map.

public interface ByteObjectMap<V>
extends Map<Byte,V>

Interface for a primitive map that uses bytes as keys.

Method Detail

get

V get(byte 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(byte 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(byte 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<ByteObjectMap.PrimitiveEntry<V>> entries()

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

containsKey

boolean containsKey(byte key)

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