# Interface NumberRangePrefixTree.NRShape

All Superinterfaces:
  `Cloneable`, `org.locationtech.spatial4j.shape.Shape`

All Known Subinterfaces:
  `NumberRangePrefixTree.UnitNRShape`

All Known Implementing Classes:

public static interface NumberRangePrefixTree.NRShape extends org.locationtech.spatial4j.shape.Shape, Cloneable
Base interface for `Shape`s this prefix tree supports. It extends `Shape` (Spatial4j) for compatibility with the spatial API even though it doesn't intermix with conventional 2D shapes.

WARNING: This API is experimental and might change in incompatible ways in the next release.

## Method Summary

Modifier and Type
Method
Description
`NumberRangePrefixTree.NRShape`
`roundToLevel(int targetLevel)`
Returns this shape rounded to the target level.
`String`
`toString()`
The result should be parseable by `NumberRangePrefixTree.parseShape(String)`.

`equals, getArea, getBoundingBox, getBuffered, getCenter, getContext, hasArea, isEmpty, relate`

## Method Details

### toString

String toString()
The result should be parseable by `NumberRangePrefixTree.parseShape(String)`.

Overrides:
  `toString` in class `Object`

### roundToLevel

NumberRangePrefixTree.NRShape roundToLevel(int targetLevel)
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.
