- Method Detail
  - isAll
```
boolean isAll()
```
    Returns:
    
    whether this instance represents the entire range or not.
  - rangeBeginInclusive
```
K rangeBeginInclusive()
```
    Returns:
    
    the beginning of this range (inclusive).
  - rangeEndExclusive
```
K rangeEndExclusive()
```
    Returns:
    
    the end of this range (exclusive).
  - includes
```
boolean includes(K key)
```
    Parameters:
    
    key - the value to check
    
    Returns:
    
    true if this key range includes the specified value, false otherwise
  - toString
```
java.lang.String toString()
```
    This method should be overridden for a readable representation of KeyRange. The generic type K should override Object's toString() as well.
    
    Overrides:
    
    toString in class java.lang.Object
  - equals
```
boolean equals(java.lang.Object o)
```
    This method should be overridden for KeyRange comparisons.
    
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
int hashCode()
```
    This method should be overridden for KeyRange comparisons.
    
    Overrides:
    
    hashCode in class java.lang.Object
