Method Detail
-
getFeature
public RichFeature getFeature()
Retrieves the feature this location is associated with. May be null. ALWAYS RETURNS NULL- Specified by:
getFeature
in interfaceRichLocation
- Returns:
- the feature.
-
sort
public void sort()
Sorts the member locations of a compound location. Does nothing for non-compound locations. Sorting depends on the compareTo() method of the member locations - usually they will be sorted by their start position.

sort
in interfaceRichLocation
-
setFeature
public void setFeature(RichFeature feature) throws ChangeVetoException
Sets the feature this location is associated with. If null, that's fine, but you won't be able to persist it to the database until you give it a not-null value. NOT IMPLEMENTED- Specified by:
setFeature
in interfaceRichLocation
- Parameters:
feature
- the feature.- Throws:
ChangeVetoException
-

does return false you should use theIterator
returned byblockIterator()
to iterate over the minimum set of contiguous blocks that make up thisLocation
ALWAYS RETURNS ZERO
-
getMin
public int getMin()
The minimum position contained.WARNING: The location will not contain every point between
getMin()

setPositionResolver
public void setPositionResolver(PositionResolver p)
Sets the resolver to use when working out actual base coordinates from fuzzy positions. This method is ignored in the empty location because positions are fixed an cannot be modified.- Specified by:
setPositionResolver
in interfaceRichLocation
- Parameters:
p
- the position resolver to use.
-
blockIterator
public Iterator blockIterator()
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 finishing at the right-most block. ALWAYS RETURNS THE EMPTY SET ITERATOR
- Specified by:
blockIterator
in interfaceLocation
- Returns:
- an Iterator over Location objects that are the maximally contiguous set of locations contained within this location

Determine if a Location is contiguous. ALWAYS RETURNS TRUE- Specified by:
isContiguous
in interfaceLocation
- Returns:
true
if and only if this Location contains every point frommin
tomax
inclusive.
-
contains
public boolean contains(int p)
Checks if this location contains a point. ALWAYS RETURNS FALSE
-
getDecorator
public Location getDecorator(Class decoratorClass)
Checks the decorator chain for an instance ofdecoratorClass and return it if found.The default behavior is to return null. If the current object is a decorator and is an instance of
decoratorClass it should return itself. Otherwise, the decorator should chain this method onto the instance it wraps. ALWAYS RETURNS NULL- Specified by:
getDecorator
in interfaceLocation
- Parameters:
decoratorClass
- the Class to check- Returns:
- a Location if an instance of this class is present in the decorator chain and null otherwise.
-
newInstance
public Location newInstance(Location loc)
Create a new instance of Location with all of the same decorators as this instance but with the data stored inloc
.The default behavior is to return
loc unchanged. If the class is a location decorator then it should instantiate an instance of the same type that decoratesloc
. ALWAYS RETURNS PASSED LOCATION- Specified by:
newInstance
in interfaceLocation
- Parameters:
loc
- the Location to use as template- Returns:
- a Location instance based on loc with the same decorators as the current instance
-
translate
public Location translate(int dist)
Create a location that is a translation of this location. ALWAYS RETURNS SELF
-
contains
public boolean contains(Location l)
Checks if this location contains the other.Abstractly, a location contains another if every point in the other location is contained within this one. ALWAYS RETURNS FALSE
-
overlaps
public boolean overlaps(Location l)
Checks if these two locations overlap, using this location's concept of overlapping.Abstractly, two locations overlap if they both contain any point. ALWAYS RETURNS FALSE
-
union
public Location union(Location l)
Return a Location containing all points in either ranges. ALWAYS RETURNS PASSED LOCATION
-
intersection
public Location intersection(Location l)
Returns a Location that contains all points common to both ranges. ALWAYS RETURNS SELF- Specified by:
intersection
in interfaceLocation
- 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
-
setCrossRefResolver
public void setCrossRefResolver(CrossReferenceResolver r)
Sets the cross ref resolver to use when retrieving remote symbols. If none is given, then the default from RichObjectFactory.getDefaultCrossRefResolver() is used. This method is ignored in the empty location because there is nothing to resolve.- Specified by:
setCrossRefResolver
in interfaceRichLocation
- Parameters:
r
- the resolver to use.
-
symbols
public SymbolList symbols(SymbolList seq)
Return the symbols in a sequence that fall within this range. ALWAYS RETURNS THE EMPTY SYMBOL LIST
-
equals
public boolean equals(Object o)
Checks if this location is equivalent to the other.Abstractly, a location is equal to another if for every point in one it is also in the other. This is equivalent to a.contains(b) && b.contains(a). You should call LocationTools.areEqual after casting l to Location. Empty Rich Locations only match other Empty Rich Locations
-
compareTo
public int compareTo(Object o)
Empty Rich Locations return 0 when compared to other Empty ones, or -1 otherwise.- Specified by:
compareTo
in interfaceComparable
