Class MetricQPtr

  • public class MetricQPtr
extends java.lang.Object
    Ptr stores a pointer and optionally takes ownership of the value.

    • Constructor Summary

      Constructors 
      Constructor Description
      MetricQPtr()
      Default constructor yielding a NULL-pointer.
      MetricQPtr​(long cPtr, boolean cMemoryOwn)  
      MetricQPtr​(MetricQ ptr)
      Do not take ownership of ptr.

      ptr can be null.

      The constructor is implicit on purpose.

      MetricQ __ref__()
      Dereferencing operator.
      void delete()  
      MetricQ deref()
      The pointer stored in the object.
      double distance​(Q q)
      The distance from the zero element to q
      double distance​(Q a, Q b)
      The distance from element a to b.

      static long getCPtr​(MetricQPtr obj)  
      MetricQ getDeref()
      Member access operator.
      boolean isNull()
      checks if the pointer is null
      boolean isShared()
      check if this Ptr has shared ownership or none
      ownership
      int size()
      The dimension of elements on which this metric operates.

      The returns -1 if the elements don't have a measure of dimension or
      if the metric works for elements of all dimensions.
