Class VisualModelCachingFactory

java.lang.Object
  pl.edu.agh.cast.model.visual.VisualModelCachingFactory

All Implemented Interfaces:

java.io.Serializable

public class VisualModelCachingFactory
extends java.lang.Object
implements java.io.Serializable

Class responsible for creating visual model elements from base model elements. This class implements a caching mechanism that creates new nodes, connections and connection groups only if they don't exist yet.

Method Detail

createNode

public Node createNode(pl.edu.agh.cast.model.base.IEntity entity)

Returns a node corresponding to the given entity, creating if it necessary.

Parameters:

entity -

Returns:

createNode

public Node createNode(pl.edu.agh.cast.model.base.IEntity entity,
                       java.util.Set<java.lang.String> currentDS)

Returns a node corresponding to the given entity, creating if it necessary. The currentDS collection holds the IDs of already processed nodes from current IDataSet. This is to prevent multiple processing of same node's attributes. If the parameter is null then such processing is performed each time.

Parameters:

entity -

currentDS -

Returns:

createConnection

public Connection createConnection(pl.edu.agh.cast.model.base.IRelation relation)

Returns a connection corresponding to the given relation, creating it if necessary. Also creates source and target nodes if they don't exist yet.

Parameters:

relation - input relation

Returns:

connection

createConnection

public Connection createConnection(pl.edu.agh.cast.model.base.IRelation relation,
                                   java.util.Set<java.lang.String> currentDS)

Returns a connection corresponding to the given relation, creating it if necessary. Also creates source and target nodes if they don't exist yet.

Parameters:

relation - input relation

currentDS - see createNode(IEntity, Set) for parameter details

Returns:

connection

createConnectionGroup

public ConnectionGroup createConnectionGroup(Connection connection)

getConnectionGroup

protected ConnectionGroup getConnectionGroup(Node source,
                                             Node target)

Find ConnectionGroup for given nodes. Create it if it does not exist.

Parameters:

source -

target -

Returns:

copyAttributes

protected void copyAttributes(pl.edu.agh.cast.model.mapper.Mappable mappable,
                              ModelElement element)

Copies entity's attributes to a node

Parameters:

mappable - attributes source

element - attributes destination

getNodeCount

getConnections

public java.util.Collection<Connection> getConnections()

wasCreatedHere

public boolean wasCreatedHere(Node node)

wasCreatedHere

public boolean wasCreatedHere(Connection connection)

wasCreatedHere

public boolean wasCreatedHere(ConnectionGroup cg)

removeNode

public void removeNode(Node node)

removeConnection

public void removeConnection(Connection c)

containsNode

public boolean containsNode(java.lang.String nodeId)

Returns true if factory has created a node with specific id.

Parameters:

nodeId - node id

Returns:

true if factory has created a node with specific id.

copyNode

public Node copyNode(Node node)

copyConnection

public Connection copyConnection(Connection conn)

copyConnectionGroup

public ConnectionGroup copyConnectionGroup(ConnectionGroup cg,
                                           Connection conn)

findNode

public Node findNode(java.lang.String nodeId)

findConnection

public Connection findConnection(java.lang.String sourceNodeId,
                                 java.lang.String targetNodeId,
                                 java.util.Date date)

findRelation

public pl.edu.agh.cast.model.base.IRelation findRelation(Connection conn)

Find relation which was used to create given connection

Parameters:

conn - The connection for which the relation is searched

Returns:

The relation which corresponds to the connection or null if not found.

initAfterDeserialization

public void initAfterDeserialization(java.util.Set<Connection> connections)

Initializes all fields after custom de-serialization

Parameters:

connections -

getRelations

protected java.util.Collection<pl.edu.agh.cast.model.base.IRelation> getRelations()

Returns all relations kept in the local (diagram) model

Returns:

All relations

setupConnectionGroups

protected void setupConnectionGroups()

TODO This is temporary fix to get back connections after deserialization. Proper implementation should be completely different - IMHO (apohllo) this class should not be serialized!
