- Constructor Detail
  - Interval
```
public Interval(String sequence,
                int start,
                int end)
```
    Constructs an interval with the supplied sequence and start and end. If the end position is less than the start position an exception is thrown.
    
    Parameters:
    
    sequence - the name of the sequence
    
    start - the start position of the interval on the sequence
    
    end - the end position of the interval on the sequence
  - Interval
```
public Interval(Locatable locatable)
```
    Constructs an interval with the supplied Locatable.
  - Interval
```
public Interval(String sequence,
                int start,
                int end,
                boolean negative,
                String name)
```
    Constructs an interval with the supplied sequence and start, end, strand and name. If the end position is less than the start position an exception is thrown.
    
    Parameters:
    
    sequence - the name of the sequence
    
    start - the start position of the interval on the sequence
    
    end - the end position of the interval on the sequence
    
    negative - true to indicate negative strand, false otherwise
    
    name - the name (possibly null) of the interval
- Method Detail
  - getSequence
```
@Deprecated
public String getSequence()
```
    Deprecated.
    use getContig() instead
    
    Gets the name of the sequence on which the interval resides. This is a simple alias of getContig()
  - isNegativeStrand
```
public boolean isNegativeStrand()
```
    Returns true if the interval is on the negative strand, otherwise false.
  - isPositiveStrand
```
public boolean isPositiveStrand()
```
    Returns true if the interval is on the positive strand, otherwise false.
  - getName
```
public String getName()
```
    Returns the name of the interval, possibly null.
  - intersects
```
public boolean intersects(Interval other)
```
    Returns true if this interval overlaps the other interval, otherwise false.
  - getIntersectionLength
```
public int getIntersectionLength(Interval other)
```
  - intersect
```
public Interval intersect(Interval that)
```
    Returns a new Interval that represents the intersection between the two intervals.
  - abuts
```
public boolean abuts(Interval other)
```
    Returns true if this interval overlaps the other interval, otherwise false.
  - length
```
public int length()
```
    Gets the length of this interval.
  - pad
```
public Interval pad(int left,
                    int right)
```
    Returns a new interval that is padded by the amount of bases specified on either side.
  - countBases
```
public static long countBases(Collection<Interval> intervals)
```
    Counts the total number of bases a collection of intervals.
  - compareTo
```
public int compareTo(Interval that)
```
    Sort based on sequence.compareTo, then start pos, then end pos with null objects coming lexically last
    
    Specified by:
    
    compareTo in interface Comparable<Interval>
  - equals
```
public boolean equals(Object other)
```
    Equals method that agrees with compareTo(Interval).
    
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object

  - getContig
```
public String getContig()
```
    Description copied from interface: Locatable
    
    Gets the contig name for the contig this is mapped to. May return null if there is no unique mapping.
    
    Specified by:
    
    getContig in interface Locatable
    
    Returns:
    
    name of the contig this is mapped to, potentially null

```
public int getStart()
```
    Specified by:
    
    getStart in interface Locatable
    
    Returns:
    
    1-based start position, undefined if getContig() == null
  - getEnd
```
public int getEnd()
```
    Specified by:
    
    getEnd in interface Locatable
    
    Returns:
    
    1-based closed-ended position, undefined if getContig() == null
