    Returns:
    
    range representing the intersection of this and other (this if equal)
    
    Throws:
    
    java.lang.IllegalArgumentException - if other does not overlap this
    
    Since:
    
    3.0.1

```
public boolean isAfter(T element)
```
    Checks whether this range is after the specified element.
    
    Parameters:
    
    element - the element to check for, null returns false
    
    Returns:
    
    true if this range is entirely after the specified element
  - isAfterRange
```
public boolean isAfterRange(Range<T> otherRange)
```
    Checks whether this range is completely after the specified range.
    This method may fail if the ranges have two different comparators or element types.
    
    Parameters:
    
    otherRange - the range to check, null returns false
    
    Returns:
    
    true if this range is completely after the specified range
    
    Throws:
    
    java.lang.RuntimeException - if ranges cannot be compared
  - isBefore
```

    Parameters:
    
    element - the element to check for, null returns false
    
    Returns:
    
    true if this range is entirely before the specified element
  - isBeforeRange
```
public boolean isBeforeRange(Range<T> otherRange)
```
    Checks whether this range is completely before the specified range.
    This method may fail if the ranges have two different comparators or element types.
    
    Parameters:
    
    otherRange - the range to check, null returns false
    
    Returns:
    
    true if this range is completely before the specified range
    
    Throws:
    
    java.lang.RuntimeException - if ranges cannot be compared

    true if using natural ordering
  - isOverlappedBy
```
public boolean isOverlappedBy(Range<T> otherRange)

```
public boolean isStartedBy(T element)
```
    Checks whether this range starts with the specified element.
    
    Parameters:

    the String representation of this range
  - toString
```
public java.lang.String toString(java.lang.String format)
```
    Formats the receiver using the given format.
    This uses Formattable to perform the formatting. Three variables may be used to embed the minimum, maximum and comparator. Use %1$s for the minimum element, %2$s for the maximum element and %3$s for the comparator. The default format used by toString() is [%1$s..%2$s].
    
    Parameters:
    
    format - the format string, optionally containing %1$s, %2$s and %3$s, not null
