  • Method Details

    • 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
      Overrides:
      defaultReturnValue in class AbstractDouble2BooleanFunction
      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
      Overrides:
      defaultReturnValue in class AbstractDouble2BooleanFunction
      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)

    • put

      public boolean put​(double k, boolean v)
      Description copied from interface: Double2BooleanFunction
      Adds a pair to the map (optional operation).
      Specified by:
      put in interface Double2BooleanFunction
      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.
      See Also:
      Function.put(Object,Object)

    • get

      public boolean get​(double k)
      Description copied from interface: Double2BooleanFunction
      Returns the value to which the given key is mapped.
      Specified by:
      get in interface Double2BooleanFunction
      Parameters:
      k - the key.
      Returns:
      the corresponding value, or the default return value if no value was present for the given key.
      See Also:
      Function.get(Object)

    • getOrDefault

      public boolean getOrDefault​(double k, boolean defaultValue)
      Description copied from interface: Double2BooleanFunction
      Returns the value associated by this function to the specified key, or give the specified value if not present.
      Specified by:
      getOrDefault in interface Double2BooleanFunction
      Parameters:
      k - the key.
      defaultValue - the value to return if not present.
      Returns:
      the corresponding value, or defaultValue if no value was present for the given key.

      Function.getOrDefault(Object, Object)

    • remove

      public boolean remove​(double k)
