## Interface NumberRangePrefixTree.UnitNRShape

- All Superinterfaces:
    Cloneable, Comparable<NumberRangePrefixTree.UnitNRShape>, NumberRangePrefixTree.NRShape, org.locationtech.spatial4j.shape.Shape
  All Known Implementing Classes:
    NumberRangePrefixTree.NRCell
  Enclosing class:
    NumberRangePrefixTree

      public static interface NumberRangePrefixTree.UnitNRShape
      extends NumberRangePrefixTree.NRShape, Comparable<NumberRangePrefixTree.UnitNRShape>

  A unit value Shape implemented as a stack of numbers, one for each level in the prefix tree. It directly corresponds to a `Cell`. Spatially speaking, it's analogous to a Point but 1D and has some precision width.
  WARNING: This API is experimental and might change in incompatible ways in the next release.

- - ### Method Detail

    - #### getLevel

          int getLevel()

      Get the prefix tree level, the higher the more precise. 0 means the world (universe).

    - #### getValAtLevel

          int getValAtLevel(int level)

      Gets the value at the specified level of this unit. level must be >= 0 and <= getLevel().

    - #### getShapeAtLevel

          NumberRangePrefixTree.UnitNRShape getShapeAtLevel(int level)

      Gets an ancestor at the specified level. It shares state, so you may want to clone() it.

    - #### roundToLevel

          NumberRangePrefixTree.UnitNRShape roundToLevel(int targetLevel)

      Description copied from interface: `NumberRangePrefixTree.NRShape`
      Returns this shape rounded to the target level. If we are already more course than the level then the shape is simply returned. The result may refer to internal state of the argument so you may want to clone it.
      Specified by:
        `roundToLevel` in interface `NumberRangePrefixTree.NRShape`

    - #### clone

          NumberRangePrefixTree.UnitNRShape clone()

      Deep clone
