public class RangeLocation
extends java.lang.Object
implements Location, java.io.Serializable

A simple implementation of Location that contains all points between getMin and getMax inclusive.

This will in practice be the most commonly used pure-java implementation.

Constructor Detail

RangeLocation

public RangeLocation(int min,
                     int max)
              throws java.lang.IndexOutOfBoundsException
Method Detail

getMin

public int getMin()
Description copied from interface: Location
The minimum position contained.
Specified by:
getMin in interface Location
Tags copied from interface: Location
Returns:
the minimum position contained

getMax

public int getMax()
Description copied from interface: Location
The maximum position contained.
Specified by:
getMax in interface Location
Tags copied from interface: Location
Returns:
the maximum position contained

overlaps

public boolean overlaps(Location l)
Description copied from interface: Location
Checks if these two locations overlap, using this locations's concept of overlaping.

Abstractly, two locations overlap if they both contain any point.

Specified by:
overlaps in interface Location
Tags copied from interface: Location
Parameters:
l - the Location to check
Returns:
true if they overlap, otherwise false

contains

public boolean contains(Location l)
Description copied from interface: Location
Checks if this location contains the other.

Abstractly, a location contains another if every point in the other location is contained within this one.

Specified by:
contains in interface Location
Tags copied from interface: Location
Parameters:
l - the Location to check
Returns:
true if this contains l, otherwise false

contains

public boolean contains(int p)
Description copied from interface: Location
Checks if this location contains a point.
Specified by:
contains in interface Location
Tags copied from interface: Location
Parameters:
p - the point to check
Returns:
true if this contains p, otherwise false

equals

public boolean equals(Location l)
Tests for object equality against another location
Parameters:
l - the location to compare against

intersection

public Location intersection(Location l)
Description copied from interface: Location
Returns a Location that contains all points common to both ranges.
Specified by:
intersection in interface Location
Tags copied from interface: Location
Parameters:
l - the Location to intersect with
Returns:
a Location containing all points common to both, or the empty range if there are no such points

union

public Location union(Location l)
Description copied from interface: Location
Return a Loctaion containing all points in either ranges.
Specified by:
union in interface Location
Tags copied from interface: Location
Parameters:
l - the Location to union with
Returns:
a Location representing the union

symbols

public SymbolList symbols(SymbolList seq)
Description copied from interface: Location
Return the symbols in a sequence that fall within this range.
Specified by:
symbols in interface Location
Tags copied from interface: Location
Parameters:
seq - the SymbolList to process
Returns:
the SymbolList containing the symbols in seq in this range

translate

public Location translate(int dist)
Description copied from interface: Location
Create a location that is a translation of this location.
Specified by:
translate in interface Location
Tags copied from interface: Location
Parameters:
dist - the distance to translate (to the right)

isContiguous

public boolean isContiguous()
Description copied from interface: Location
Determine if a Location is contiguous.
Specified by:
isContiguous in interface Location
Tags copied from interface: Location
Returns:
true if and only if this Location contains every point from min to max inclusive.

blockIterator

public java.util.Iterator blockIterator()
Description copied from interface: Location
Return an Iterator over the set of maximal contiguous sub-locations.

Given any location, it can be considered to contain zero or more maximal contiguous blocks of width 1 or greater. The empty location is composed from nothing. A contiguous location is composed from itself. A non-contiguous location is composed from contiguous blocks seperated by gaps.

This method should return an Iterator over these maximally contiguous blocks starting with the left-most block, and finnishing at the right-most block.

Specified by:
blockIterator in interface Location
Tags copied from interface: Location
Returns:
an Iterator over Location objects that are the maximaly contiguous set of locations contained within this location

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
