    Ptr stores a pointer and optionally takes ownership of the value.
    • Constructor Detail

      • MetricLinePtr

        public MetricLinePtr​(long cPtr,
                             boolean cMemoryOwn)
      • MetricLinePtr

        public MetricLinePtr()
        Default constructor yielding a NULL-pointer.
      • MetricLinePtr

        public MetricLinePtr​(MetricLine ptr)
        Do not take ownership of ptr.

        ptr can be null.

      • equals

        public boolean equals​(MetricLine p)
      • isShared

        public boolean isShared()
        check if this Ptr has shared ownership or none
        ownership
        Returns:

        b - [in] second element
        Returns:
        the distance
      • size

        public int size()
        The dimension of elements on which this metric operates.
