    • Method Detail

      • canAdd

        boolean canAdd​(int index)
        Parameters:
        index - data set point index
        Returns:
        true: if a new data point can be added at the specified data point.

      • canChange

        default boolean canChange​(int index)
        Determines if the specified data point can be modified.
        Parameters:
        index - data point index
        Returns:
        default is true

      • canDelete

        boolean canDelete​(int index)
        Parameters:
        index - data set point index
        Returns:
        true: if the specified data point can be deleted.

      • isAcceptable

        default boolean isAcceptable​(int index,
                             double... newValue)
        Determines if the specified point can be accepted by the data set. The specified point may be a new point (in this case index should be -1) or existing point. This method can be used e.g. to make sure that the new point doesn't have the same X coordinate as existing point.
        Parameters:
        index - index of the point being modified or -1 if it is a new point
        newValue - coordinate list of the considered point
        Returns:
        true if the point is acceptable by the data set, false otherwise

      • isEditable

        boolean isEditable​(int dimIndex)
        Parameters:
        dimIndex - the dimension index (ie. '0' equals 'X', '1' equals 'Y')
        Returns:
        true: if the horizontal values can be modified
