Constructor Detail

VisualSchemaConnection

public VisualSchemaConnection()

Default constructor.

VisualSchemaConnection

protected VisualSchemaConnection(Type type)

VisualSchemaConnection

protected VisualSchemaConnection(IVisualSchemaDataSet dataSet,
                                 Type type,
                                 ISchemaConnection elementReference)

The constructor for subclasses which wraps the schema connection.

Parameters:

dataSet - The data set of this connection.

type - The type of this connection.

elementReference - The referenced element of presentation model.

VisualSchemaConnection

public VisualSchemaConnection(IVisualSchemaDataSet dataSet,
                              IVisualSchemaNode visualSourceNode,
                              IVisualSchemaNode visualTargetNode,
                              ISchemaConnection connection)

Constructor for creating new visual connection associated to given connection.

Parameters:

dataSet - data set which visual connection belongs to

visualSourceNode - source node of this connection

visualTargetNode - target node of this connection

connection - model connection which is visualized by this object

VisualSchemaConnection

public VisualSchemaConnection(IVisualSchemaDataSet dataSet,
                              ISchemaConnection elementReference)

The public constructor which wraps the schema connection.

Parameters:

dataSet - The data set of this connection.

elementReference - The referenced element of presentation model.

Method Detail

isDirected

public boolean isDirected()

Indicates if the connection is directed, i.e. it just binds a pair of nodes or the order of nodes is significant. The general semantics of the connection says that there should be only one connection (in given direction) of given type between two nodes. Undirected connection may be perceived as two connections pointing in both directions.

Specified by:

isDirected in interface IVisualSchemaConnection

Returns:

True if the order of nodes is significant.

See Also:

IVisualSchemaConnection.isDirected()

getBendpoints

public List<SchemaConnectionBendpoint> getBendpoints()

Returns list of bend points.

Specified by:

getBendpoints in interface IVisualSchemaConnection

Returns:

list of bend points

See Also:

pl.edu.agh.cast.schema.model.presentation.ISchemaConnection#getBendpoints()

setBendpoints

public void setBendpoints(List<SchemaConnectionBendpoint> bendpoints)

Sets list of bend points.

Specified by:

setBendpoints in interface IVisualSchemaConnection

Parameters:

bendpoints - list of bend points

See Also:

pl.edu.agh.cast.schema.model.presentation.ISchemaConnection#setBendpoints(java.util.List)

replicateTo

public VisualSchemaConnection replicateTo(Object replica)
                                   throws IllegalArgumentException,
                                          ReplicationException

Replicates this instance state to given replica object. The replica should be an instance of replicated instance's class (same class or subclass).

Replicates element type and ID.

Replicates the direction flag, source and target nodes are null empty.

Specified by:

replicateTo in interface IReplicable

Overrides:

replicateTo in class VisualElement<ISchemaConnection>

Parameters:

replica - the object to replicate to

Returns:

the replica object (the same instance as given)

Throws:

IllegalArgumentException - if given object is null or of invalid type

ReplicationException - if replication fails

See Also:

VisualElement.replicateTo(java.lang.Object)

replicate

public VisualSchemaConnection replicate()
                                 throws ReplicationException

Returns a replicated instance of this instance.

Specified by:

replicate in interface IReplicable

Overrides:

replicate in class AbstractElement

Returns:

replicated instance

Throws:

ReplicationException - if replication fails

See Also:

IReplicable.replicate()
