Class NumberRange

java.lang.Object
fc.util.Range
fc.util.NumberRange
public class NumberRange extends Range
A range of integral values.

Note, many methods in this particular class have the same signatures as in the apache commons.lang package but the implementation was strictly clean-room.

Thread Safety: This class is not thread safe in the face of any concurrent modification (via changing the start/end numbers or union/intersection operations).

    • NumberRange

      public NumberRange(long start, long end)
      Constructs a number range between the specified start and end numbers (both inclusive).
      Throws:
      IllegalArgumentException - if the end number is lesser (via a < comparison) than the start number (equal to the start number is ok)

      public long getStart()
      Get the start number for this number range

    • getEnd

      public long getEnd()
      Get the end number for this number range.

    • inRange

      public boolean inRange(long c)
      Is the passed in number inside this range

    • setEnd

      public void setEnd(long c)
      Sets the end number for this number range
      Parameters:
      c - the end number
      Throws:
      IllegalArgumentException - if the end number is lesser (via a < comparison) than the current start number (equal to the start number is ok)

    • setStart

      public void setStart(long c)
      Set the start number for this number range
      Throws:
