  • Method Details

    • size

      public int size()
      Specified by:
      size in interface it.unimi.dsi.fastutil.Function<K,​java.lang.Byte>

    • defaultReturnValue

      public byte defaultReturnValue()
      Description copied from interface: Reference2ByteFunction
      Gets the default return value.

      This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

      Specified by:
      defaultReturnValue in interface Reference2ByteFunction<K>
      Overrides:
      defaultReturnValue in class AbstractReference2ByteFunction<K>
      Returns:
      the current default return value.

    • defaultReturnValue

      public void defaultReturnValue​(byte defRetValue)
      Description copied from interface: Reference2ByteFunction
      Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
      Specified by:
      defaultReturnValue in interface Reference2ByteFunction<K>
      Overrides:
      defaultReturnValue in class AbstractReference2ByteFunction<K>
      Parameters:
      defRetValue - the new default return value.
      See Also:
      Reference2ByteFunction.defaultReturnValue()

    • containsKey

      public boolean containsKey​(java.lang.Object k)
      Specified by:
      containsKey in interface it.unimi.dsi.fastutil.Function<K,​java.lang.Byte>

    • put

      public byte put​(K k, byte v)
      Description copied from interface: Reference2ByteFunction
      Adds a pair to the map (optional operation).
      Specified by:
      put in interface Reference2ByteFunction<K>
      Parameters:
      k - the key.
      v - the value.
      Returns:
      the old value, or the default return value if no value was present for the given key.

      Function.put(Object,Object)

    • getByte

      public byte getByte​(java.lang.Object k)
      Description copied from interface: Reference2ByteFunction
      Returns the value to which the given key is mapped.
      Specified by:
      getByte in interface Reference2ByteFunction<K>
      Parameters:
      k - the key.
      Returns:
      the corresponding value, or the default return value if no value was present for the given key.
