      Constructor Description
      IndexRange ​(int start, int end)
      Creates an instance of IndexRange representing the range between start and end.

    • Method Summary

      All Methods
      Modifier and Type Method Description
      boolean equals ​(Object object)
      Indicates whether some other object is "equal to" this one.
      int getEnd ​()
      Returns the end position of the range (exclusive).
      int getLength ​()
      Returns the length of the range.
      int getStart ​()
      Returns the start position of the range.
      int hashCode ​()
      Returns a hash code for this Range object.
      static IndexRange normalize ​(int v1, int v2)
      Convenience method to create an IndexRange instance that has the smaller value as the start index, and the larger value as the end index.
      String toString ​()
      Returns a string representation of this Range object.
      static IndexRange valueOf ​(String value)
      Convenience method to parse in a String of the form '2,6', which will create an IndexRange instance with a start value of 2, and an end value of 6.
