- Method Detail
  - getLeftEndpoint
```
E getLeftEndpoint()
```
    Returns:
    
    The left endpoint of this range where the left <= right
  - getRightEndpoint
```
E getRightEndpoint()
```
    Returns:
    
    The right endpoint of this range where the left <= right
  - isLeftClosed
```
boolean isLeftClosed()
```
    Returns:
    
    True if this range includes the left endpoint.
  - isRightClosed
```
boolean isRightClosed()
```
    Returns:
    
    True if this range includes the right endpoint.
  - contains
```
boolean contains(E elem)
```
    Parameters:
    
    elem - An element to test
    
    Returns:
    
    True if elem is a proper element in the set of elements defining this range.
  - contains
```
boolean contains(ME range)
```
    Parameters:
    
    range - An range to test for containment
    
    Returns:
    
    True if range's endpoints are proper elements in the set of elements defining this range.
  - isReversed
```
boolean isReversed()
```
    Returns:
    
    True if this range iterates from the right by default e.g., if the range is specified in reverse order: 10..1, a reverse range results
