Class AnnotationChangeCoalescer

java.lang.Object
  apollo.gui.AnnotationChangeCoalescer

All Implemented Interfaces:: ControlledObjectI, java.io.Serializable

public class AnnotationChangeCoalescer
extends java.lang.Object
implements ControlledObjectI

The AnnotationChangeCoalescer holds all the AnnotationChangeEvents for the current edit along with a representation of the feature tree before the edit began.

NOTE: THIS CLASS IS NOT FULLY IMPLEMENTED.

As edits are added to the AnnotationChangeCoalescer it checks to see if they can be coalesced - for example if you delete all the exons in a transcript and then delete the transcript the edit can be coalesced into a delete transcript - all the delete exon AnnotationChangeEvents can be removed from the changes vector.

A new AnnotationChangeCoalescer should be created at the start of each edit in the AnnotationEditor because it is important that the tree representing the underlying features (the origTree) is current. After that it is simply a matter of adding changes using addChanges. At the end of the edit executeChanges is called to send the AnnotationChangeEvents to all the listeners.

Remember that the Drawable tree will be in tht origTree state until executeChanges is called. This is VERY important for deciding which edits are necessary.

delete exon
Check if its in the add list
Look to see if any of the current parents of the exon have
been deleted.
delete transcript
Check if its in the add list
Look to see if any of the current parents of the transcript
have been deleted.
Look to see if any of the previous children of the
transcript have been deleted - remove those.
delete gene
Check if its in the add list
Look to see if any of the previous children of the
gene have been deleted - remove those.
add exon
Add to add list
Look to see if any of the current parents of the exon have
already been added.
Could do error check if add to parents which have already
been deleted.
add transcript
Add to add list
add gene
Add to add list
other exon
other transcript
other gene
