        public ContinuousPiecewiseLinearFunction​(java.util.Map<java.math.BigDecimal,​java.math.BigDecimal> cornerPoints)
        Constructs a new PieceWiseLinear function with a restricted domain interval
        Parameters:
        cornerPoints - A map with key = x-values and value = y-values. The map has to include all corner points of the function, including lower and upper end of domain.

      • getCornerPoints

        public java.util.List<java.util.AbstractMap.SimpleImmutableEntry<java.math.BigDecimal,​java.math.BigDecimal>> getCornerPoints()
        Provides a list with all corner point (X, Y) pairs, sorted with increasing X. The return type is a list (instead of a sorted map) to allow easy indexing.
        Returns:
        a list of the corner points
