      public boolean test​(double operand)
      Description copied from interface: Double2BooleanFunction
      Specified by:
      test in interface Double2BooleanFunction
      Specified by:
      test in interface java.util.function.DoublePredicate

    • apply

      @Deprecated public java.lang.Boolean apply​(java.lang.Double key)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      apply in interface it.unimi.dsi.fastutil.Function<java.lang.Double,​java.lang.Boolean>
      Specified by:
      apply in interface java.util.function.Function<java.lang.Double,​java.lang.Boolean>

    • size

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

    • defaultReturnValue

      public boolean defaultReturnValue()
      Description copied from interface: Double2BooleanFunction
      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 Double2BooleanFunction
      Returns:
      the current default return value.

    • defaultReturnValue

      public void defaultReturnValue​(boolean defRetValue)
      Description copied from interface: Double2BooleanFunction
      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 Double2BooleanFunction
      Parameters:
      defRetValue - the new default return value.
      See Also:
      Double2BooleanFunction.defaultReturnValue()

    • containsKey

      public boolean containsKey​(double k)
      Description copied from interface: Double2BooleanFunction
      Returns true if this function contains a mapping for the specified key.

      Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

      Specified by:
      containsKey in interface Double2BooleanFunction
      Parameters:
      k - the key.
      Returns:
      true if this function associates a value to key.
      See Also:
      Function.containsKey(Object)

    • containsKey

      @Deprecated public boolean containsKey​(java.lang.Object k)

    • put

      public boolean put​(double k, boolean v)
      Description copied from interface: Double2BooleanFunction
      Adds a pair to the map (optional operation).
