Class LineCPtr

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

    • Constructor Summary

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

      ptr can be null.

      The constructor is implicit on purpose.

    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      Line __ref__()
      Dereferencing operator.
      Vector3D closestPoint​(Vector3D point)
      Finds a point on the line closest to specified point.

      For the purposes of this calculation, the line is treated as infinitely extending
      geometric entity, without begining nor end.
      TriMeshPtr createMesh​(int resolution)  
      void delete()  
      Line deref()
      The pointer stored in the object.
      Vector3D dir()
      Get a direction vector u = normalize(p2 - p1).
      double distance​(Line line)
      Calculates the shortest distance to another line.

      For the purposes of this calculation, the lines are treated as infinitely extending
      geometric entity, without begining nor end.
      double distance​(Vector3D point)
      Calculates the shortest distance from a point to the line.

      For the purposes of this calculation, the line is treated as infinitely extending
      geometric entity, without begining nor end.
      boolean equals​(Line p)  
      static long getCPtr​(LineCPtr obj)  
      Line getDeref()
      Member access operator.
      Q getParameters()  
      GeometryData.GeometryType getType()  
      boolean isNull()
      checks if the pointer is null
      boolean isShared()
      check if this Ptr has shared ownership or none
      ownership
