  public ObjectSet<Byte2ObjectMap.Entry<V>> byte2ObjectEntrySet()
  
  Description copied from interface: Byte2ObjectMap
  
  Returns a type-specific set view of the mappings contained in this map.
  This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

- computeIfAbsent
  
  public V computeIfAbsent(byte key, IntFunction<? extends V> mappingFunction)
  
  Description copied from interface: Byte2ObjectMap
  
  If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.
  Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the mappingFunction cannot return null. If such a behavior is needed, please use the corresponding nullable version.
  
  Specified by:
  
  computeIfAbsent in interface Byte2ObjectMap<V>
  
  Parameters:
  
  key - key with which the specified value is to be associated.
  
  mappingFunction - the function to compute a value.
  
  Returns:
  
  the current (existing or computed) value associated with the specified key.
  
  See Also:
  
  Map.computeIfAbsent(Object, java.util.function.Function)
- computeIfAbsentPartial
  
  public V computeIfAbsentPartial(byte key, Byte2ObjectFunction<? extends V> mappingFunction)
  
  Description copied from interface: Byte2ObjectMap
  
  If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.
  This version of computeIfAbsent() uses a type-specific version of fastutil's Function. Since Function has a containsKey() method, it is possible to avoid adding a key by having containsKey() return false for that key.
  
  Specified by:
  
  computeIfAbsentPartial in interface Byte2ObjectMap<V>
  
  Parameters:
  
  key - key with which the specified value is to be associated.
  
  mappingFunction - the function to compute a value.
  
  Returns:
  
  the current (existing or computed) value associated with the specified key.
  
  See Also:
  
  Map.computeIfAbsent(Object, java.util.function.Function)
- computeIfPresent
  
  public V computeIfPresent(byte key, BiFunction<? super Byte,? super V,? extends V> remappingFunction)
  
  Description copied from interface: Byte2ObjectMap
  
  If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.
  
  Specified by:
  
  computeIfPresent in interface Byte2ObjectMap<V>
  
  Parameters:
  
  key - key with which the specified value is to be associated.
  
  remappingFunction - the function to compute a value.
  
  Returns:
  
  the new value associated with the specified key, or the default return value if none.
  
  See Also:
  
  Map.computeIfPresent(Object, java.util.function.BiFunction)
- compute
  
  public V compute(byte key, BiFunction<? super Byte,? super V,? extends V> remappingFunction)
  
  Description copied from interface: Byte2ObjectMap
  
  Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).
  If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.
  
  Specified by:
  
  compute in interface Byte2ObjectMap<V>
  
  Parameters:
  
  key - key with which the specified value is to be associated.
  
  remappingFunction - the function to compute a value.

- merge
  
  public V merge(byte key, V value, BiFunction<? super V,? super V,? extends V> remappingFunction)
  
  Description copied from interface: Byte2ObjectMap
  
  If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.
  
  Specified by:
  
  merge in interface Byte2ObjectMap<V>
  
  Parameters:
  
  key - key with which the resulting value is to be associated.
  
  value - the non-null value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.
  
  remappingFunction - the function to recompute a value if present.
  
  Returns:
  
  the new value associated with the specified key, or the default return value if no value is associated with the key.
