Class ModelTopology

java.lang.Object

net.mdatools.modelant.core.operation.model.topology.ModelTopology

public class ModelTopology
extends Object

This class allows structurally comparing models, independently of their actual meta-models. It is intended to serve the model change tracking.

 Usage:
   new ModelTopology()
   load()
   findEquals() / findEquals(EquivalenceMap) returns the element matches
   getNotProcessed() returns not matched elements
 

NOTE: The instances should not be reused

Method Detail

isEmpty

public boolean isEmpty()

Returns:

true iff getNodes() is empty

load

public void load(MatchingCriteria criteria,
                 Collection<javax.jmi.reflect.RefObject> elements)

Load into this model topology the listed associations and attributes, so that model processing would treat as equal any model elements with same values of the listed attributes and equal objects bound in the listed associations.

Parameters:

criteria - is a not null criteria defining the attribute names to evaluate for all model elements

elements - is a non-null list of model elements to order

getGenerationOfReady

public final ArrayList<Node<javax.jmi.reflect.RefObject>> getGenerationOfReady()

Returns:

a copy of the current ready nodes, this way forming a "generation of ready nodes", that could be manipulated independently of the current set of ready nodes

remove

public final void remove(Collection<javax.jmi.reflect.RefObject> equivalents)

Removes from this topology all nodes from the equivalence class the representative is of

Parameters:

equivalents - not null

removeFromTopology

public void removeFromTopology(Collection<Node<javax.jmi.reflect.RefObject>> nodes)

This method excludes the nodes provided from the owner topology, decreases the level of all nodes that refer this and rearranges the topology to reflect level of the changed nodes.

Parameters:

nodes - is a collection of ready nodes

removeFromReadyNodes

public void removeFromReadyNodes(List<Node<javax.jmi.reflect.RefObject>> targetGenerationReady)

Exclude the listed nodes from the READY list, but keep them in the topology itself

Parameters:

targetGenerationReady - not null

getContents

public List<javax.jmi.reflect.RefObject> getContents()

Returns:

a non-null list of model elements that where left in the topology.

clear

public void clear()

Leave this topology empy and ready to load another model

toString

public String toString()

Overrides:

toString in class Object
