Class org.apache.accumulo.core.data.Range

Examples of org.apache.accumulo.core.data.Range.clip()

org.apache.accumulo.core.data.Range.clip()
Creates a range which represents the intersection of this range and the passed in range. The following example will print true.
```
 Range range1 = new Range("a", "f"); Range range2 = new Range("c", "n"); Range range3 = range1.clip(range2); System.out.println(range3.equals(new Range("c", "f"))); 
```
@return the intersection @throws IllegalArgumentException if ranges does not overlap

    
    Range tabletRange = extent.toDataRange();
    for (Range range : ranges) {
      // do a test to see if this range falls within the tablet, if it does not
      // then clip will throw an exception
      tabletRange.clip(range);
    }
