Class ConnectionSet
java.lang.Object
org.jgraph.graph.ConnectionSet
- Serializable
public class ConnectionSet
extends java.lang.Object
implements Serializable
An object that represents a set of connections. Connections are equal, if
equals returns true. Connections that are added later replace earlier
connections.
protected Set | connections - Contents of the connection set.
|
protected Set | edges - Set of changed edges for the connection set.
|
ConnectionSet() - Constructs an empty ConnectionSet.
|
ConnectionSet(Object edge, Object source, Object target) - Constructs a ConnectionSet with two Connections (to the source and target
port of the edge).
|
ConnectionSet(Object edge, Object port, boolean source) - Constructs a ConnectionSet with one Connection.
|
ConnectionSet(Set connections) - Constructs a connection set containing the specified connections and
updates the set of changed edges.
|
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 .
|
void | connect(Object edge, Object source, Object target) - Connect
edge to source and
target in the connection set.
|
void | connect(Object edge, Object port, boolean source) - Connect
edge to port passed in.
|
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 .
|
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() - Returns a
Set for the edges in this connection set.
|
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.

connections
protected Set connections
Contents of the connection set.
edges
protected Set edges
Set of changed edges for the connection set.
ConnectionSet
public ConnectionSet()
Constructs an empty ConnectionSet.
ConnectionSet
public ConnectionSet(Object edge,
Object source,
Object target)
Constructs a ConnectionSet with two Connections (to the source and target
port of the edge).
ConnectionSet
public ConnectionSet(Object edge,
Object port,
boolean source)
Constructs a ConnectionSet with one Connection.
ConnectionSet
public ConnectionSet(Set connections)
Constructs a connection set containing the specified connections and
updates the set of changed edges.
addConnections
public void addConnections(CellView[] views)
Adds the connections in views
to the connection set.
clone
public ConnectionSet clone(Map map)
Creates a new connection set based on this connection set, where the
edges, and ports are mapped using
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.
connect
public void connect(Object edge,
Object source,
Object target)
Connect edge
to source
and
target
in the connection set. The previous connections
between edge
and its source and target are replaced in the
set.
connect
public void connect(Object edge,
Object port,
boolean source)
Connect 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.
connect
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
.
connections
public Iterator connections()
Returns an Iterator
for the connections in this set.
create
public 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
.
disconnect
public void disconnect(Object edge)
Disconnect edge
from source
and
target
in the connection set. The previous connections
between edge
and its source and target are replaced in the
set.
disconnect
public void disconnect(Object edge,
boolean source)
Disconnect 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.
getChangedEdges
public Set getChangedEdges()
Returns a Set
for the edges in this connection set.
getConnections
public Set getConnections()
getEdges
public Set getEdges()
- the edges making us this connection set
getPort
public 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.
isEmpty
public boolean isEmpty()
Returns true
if the connection set is empty.
setConnections
public void setConnections(Set set)
setEdges
public void setEdges(Set set)
size
public int size()
Returns the number of (edge, port)-pairs.
