      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      applyAsInt in interface Byte2IntFunction

    • apply

      @Deprecated public java.lang.Integer apply​(java.lang.Byte key)
      Deprecated.
      Please use the corresponding type-specific method instead.
      This is equivalent to calling Function.get(Object).
      Specified by:
      apply in interface Function<java.lang.Byte,​java.lang.Integer>
      Specified by:

    • size

      public int size()
      Description copied from interface: Function
      Returns the intended number of keys in this function, or -1 if no such number exists.

      Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.

      Specified by:
      size in interface Function<java.lang.Byte,​java.lang.Integer>
      Returns:
      the intended number of keys in this function, or -1 if that number is not available.
    • defaultReturnValue

      public int defaultReturnValue()
      Description copied from interface: Byte2IntFunction
      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 Byte2IntFunction
      Returns:

    • defaultReturnValue

      public void defaultReturnValue​(int defRetValue)
      Description copied from interface: Byte2IntFunction
      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 Byte2IntFunction
      Parameters:
      defRetValue - the new default return value.

      Byte2IntFunction.defaultReturnValue()
    • containsKey

      public boolean containsKey​(byte k)
