java.lang.Objectorg.jgraph.graph.ConnectionSet
An object that represents a set of connections. Connections are equal, if equals returns true. Connections that are added later replace earlier connections.
| Nested Class Summary | |
static class |
ConnectionSet.Connection
Object that represents the connection between an edge and a port. |
| Field Summary | |
protected Set |
connections
Contents of the connection set. |
protected Set |
edges
Set of changed edges for the connection set. |
| Constructor Summary | |
ConnectionSet()
Constructs an empty ConnectionSet. |
|
ConnectionSet(Object edge,
Object port,
boolean source)
Constructs a ConnectionSet with one Connection. |
|
ConnectionSet(Object edge,
Object source,
Object target)
Constructs a ConnectionSet with two Connections (to the source and target port of the edge). |
|
ConnectionSet(Set connections)
Constructs a connection set containing the specified connections and updates the set of changed edges. |
|
| Method Summary | |
void |
addConnections(CellView[] views)
Adds the connections in views to the connection set. |
ConnectionSet |
clone(Map map)
Creates a new connection set based on this connection set, where the edges, and ports are mapped using map. |
protected static void |
connect(ConnectionSet cs,
Object edge,
Object port,
boolean source,
boolean disconnect)
Connect or disconnect edge from source and
target in cs based on
disconnect. |
void |
connect(Object edge,
Object port,
boolean source)
Connect edge to port passed in. |
void |
connect(Object edge,
Object source,
Object target)
Connect edge to source and
target in the connection set. |
Iterator |
connections()
Returns an Iterator for the connections in this set. |
static ConnectionSet |
create(GraphModel m,
Object[] cells,
boolean disconnect)
Returns a connection set that represents the connection or disconnection of cells in model based on
disconnect. |
void |
disconnect(Object edge)
Disconnect edge from source and
target in the connection set. |
void |
disconnect(Object edge,
boolean source)
Disconnect edge from port. |
Set |
getChangedEdges()
Deprecated. Use getEdges |
Set |
getConnections()
|
Set |
getEdges()
|
Object |
getPort(Object edge,
boolean source)
Returns the source or target of the specified edge in this connection set or null if the connection set contains no corresponding entry for the edge. |
boolean |
isEmpty()
Returns true if the connection set is empty. |
void |
setConnections(Set set)
|
void |
setEdges(Set set)
|
int |
size()
Returns the number of (edge, port)-pairs. |

| Method Detail |
public static ConnectionSet create(GraphModel m,
Object[] cells,
boolean disconnect)
cells in model based on
disconnect.
protected static void connect(ConnectionSet cs,
Object edge,
Object port,
boolean source,
boolean disconnect)
edge from source and
target in cs based on
disconnect.
public void addConnections(CellView[] views)
views to the connection set.
public void connect(Object edge,
Object source,
Object target)
edge to source and
target in the connection set. The previous connections
between edge and its source and target are replaced in the
set.
public void connect(Object edge,
Object port,
boolean source)
edge to port passed in. The
source indicates if port is the source of
edge object. The previous connections between
edge and its source or target in the set is replaced.
public void disconnect(Object edge)
edge from source and
target in the connection set. The previous connections
between edge and its source and target are replaced in the
set.
public void disconnect(Object edge,
boolean source)
edge from port.
source indicates if port is the source of
edge. The previous connections between edge
and its source or target in the set is replaced.
public boolean isEmpty()
true if the connection set is empty.
public int size()
public Iterator connections()
Iterator for the connections in this set.
public Set getChangedEdges()
Set for the edges in this connection set.
public Object getPort(Object edge,
boolean source)
public ConnectionSet clone(Map map)
map. If a port is not
found, the old port is used. If both, the edge and the port are not in
map, the entry is ignored.
Note: Consequently, unselected edges are only reconnected at the first "paste" after a "cut", because in this case the ConnectionSet is not cloned.
