    • containsFacet

      public boolean containsFacet(MeshFacet meshFacet)
      Description copied from interface: MeshDistances
      Checks whether this measurement includes the given facet.
      Specified by:
      containsFacet in interface MeshDistances
      Parameters:
      meshFacet - mesh facet to be checked
      Returns:
      true if the facet is among the measured facets.

    • containsFacets

      public boolean containsFacets(Collection<MeshFacet> meshFacets)
      Description copied from interface: MeshDistances
      Checks whether this measurement includes all given facets.
      Specified by:
      containsFacets in interface MeshDistances
      Parameters:
      meshFacets - mesh facets to be checked
      Returns:
      true if all facets are among the measured facets.

    • getFacetMeasurement

      public FacetDistances getFacetMeasurement(MeshFacet meshFacet)
      Description copied from interface: MeshDistances
      Returns decorated distance measurement for the given facet or null
      Specified by:
      getFacetMeasurement in interface MeshDistances
      Parameters:
      meshFacet - required mesh facet
      Returns:
      the decorated distance measurement or null

    • distancesAsMap

      public Map<MeshFacet,List<Double>> distancesAsMap()
      Description copied from interface: MeshDistances
      Transforms FacetDistance objects into the map of the lists of distance values
      Specified by:
      distancesAsMap in interface MeshDistances
      Returns:
      a map of distance values for each measured facet (nearest neighbors are omitted)

    • stream

      public Stream<DistanceRecord> stream()
      Description copied from interface: MeshDistances
      Returns a stream of all decorated distance measurements (all vertices of all facets). The stream includes possible invalid measurements, i.e., point distances with infinite or NaN values, with missing nearing neighbors, etc. Use stream filtering to remove them.
