public final class OrganismAllelePair
extends EngineObject
implements java.io.Serializable, java.beans.PropertyChangeListener

This class represents a pair of organism alleles or, in the case of sex chromosomes, it can represent a single allele on a single chromosome. This type of object should only exist for organisms of a diploid species.

In general this object is created when the organism is created and never changes from that time on. It's essentially a convenience object, especially for the tree view as this object represents a node in the tree view.

An instance of this class is contained by one organism chromosome pair.

An object of this class will generate the following property change events:

Constructor Detail

OrganismAllelePair

public OrganismAllelePair(OrganismChromosomePair anOrganismChromosomePair,
                          OrganismAllele aFirstOrganismAllele,

Create a new organism allele pair from the two given organism alleles.

Parameters:
anOrganismChromosomePair - OrganismChromosomePair - containing organism chromosome pair, may not be null
aFirstOrganismAllele - OrganismAllele - a first organism allele, may not be null
aSecondOrganismAllele - OrganismAllele - a second organism allele, may be null
Throws:
java.lang.IllegalArgumentException - - input argument(s) illegal

OrganismAllelePair

public OrganismAllelePair(OrganismChromosomePair anOrganismChromosomePair,
                          java.lang.String anElementName,
                          int anElementID,
                          com.sun.xml.parser.Parser anXMLParser,
                          ImportContext importContext)
Create a new organism allele pair and start handling XML parsing events to set the properties of this object.

Parameters:
anOrganismChromosomePair - OrganismChromosomePair - the enclosing organism chromosome pair for this new organism allele pair
anElementName - String - the element name
anElementID - int - the element id
anXMLParser - com.sun.xml.parser.Parser - the element parser
importContext - ImportContext - import context for mapping ids from file to this world
Throws:
java.lang.IllegalArgumentException - - input arguments illegal
Method Detail

startElement

public void startElement(java.lang.String anElementName,
                         org.xml.sax.AttributeList amap)
                  throws org.xml.sax.SAXException
Handle notification that the parser has hit the start of a new element with the given name and attributes.

For internal elements (elements that are non-EngineObject instance variables of this object), call xmlElementContext.startElement() and xmlElementContext will receive the remaining element notifications. For external elements (elements that are EngineObject instance variables of this object), create an object of the appropriate class and that object will receive the remaining element notifications.

Overrides:
startElement in class org.xml.sax.HandlerBase
Parameters:
anElementName - String - name of element
amap - AttributeList - an attribute list

characters

public void characters(char[] ch,
                       int start,

                throws org.xml.sax.SAXException
Receive notification of character data.
Overrides:

                                int start,
                                int length)

public void endElement(java.lang.String anElementName)
                throws org.xml.sax.SAXException
Handle notification that the parsing of the given element has ended.
Overrides:
endElement in class org.xml.sax.HandlerBase
Parameters:
anElementName - String - the element name

delete

public void delete()
Delete this object, notifying parent objects and deleting any child objects.

When this method is called, a property change event is generated for the property named EngineProp.DELETED.

Overrides:
delete in class EngineObject

delete

public void delete(boolean notifyChange)

toString

public java.lang.String toString()
Return a string representation of this object, usually the object's name.

Overrides:
toString in class EngineObject
Returns:
String - string representation of object

getOrganismChromosomePair

public OrganismChromosomePair getOrganismChromosomePair()
Returns the organism allele pair's chromosome organism pair.

Returns:
OrganismChromosomePair - containing organism chromosome pair, never null

getOrganism

public Organism getOrganism()
Returns the allele pair's organism.

Returns:
Organism - the allele pair's organism, may not be null

getSpecies

public Species getSpecies()
Returns the organism chromosome pair's species.

Returns:
Species - organism chromosome pair's species, may not be null

getWorld

public World getWorld()
Get the world containing this object.

Overrides:
getWorld in class EngineObject
Returns:
World - the world containing this object, never null.

getFirstOrganismAllele

public OrganismAllele getFirstOrganismAllele()
Get the first organism allele of this pair.

Returns:
OrganismAllele - the first organism allele in this pair, never null.

getSecondOrganismAllele

public OrganismAllele getSecondOrganismAllele()
Get the second organism allele of this pair.

Returns:
OrganismAllele - the second organism allele in this pair, never null.

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent event)
Handle property change events
Specified by:
propertyChange in interface java.beans.PropertyChangeListener
Parameters:
event - PropertyChangeEvent - the property change event

writeToStream

public void writeToStream(java.io.PrintWriter stream)
                   throws java.io.IOException
Writes this object to the given stream in XML format. Usually this method is used to write the object to a file for saving it, but that is potentially not the only use.

We could supply a default implementation that knows how to write the id value. But that convenience is not chosen because it's never correct to use just this implementation of these methods, so I'd rather have a compilation fail if a derived class fails to implement this method.

The inverse of this method is a constructor that takes a org.xml.sax.Parser argument and other arguments.

Overrides:
writeToStream in class EngineObject
Parameters:
stream - PrintWriter - print stream
Throws:
java.lang.IllegalArgumentException - - input arguments illegal
java.io.IOException - - an IO error occurred in java libraries
