All Known Implementing Classes:

SchemaConnection

public interface ISchemaConnection
extends ISchemaElement<IElement>

Interface which describes a single connection between two SchemaNode objects in a schema diagram. A ISchemaConnection instance can derive one or more IManyToManyRelation objects and expose summaries of them via properties.

Method Detail

getSourceNode

@PropertyGetter(name="SOURCE_NODE",
                type=REFERENCE,
                matchable=true)
ISchemaNode getSourceNode()

Gets source node. If a connection is indirected this node is represented just as one of the connection's end.

Returns:

source node

getTargetNode

@PropertyGetter(name="TARGET_NODE",
                type=REFERENCE,
                matchable=true)
ISchemaNode getTargetNode()

Gets target node. If a connection is indirected this node is represented just as one of the connection's end.

Returns:

target node

setSourceNode

void setSourceNode(ISchemaNode node)

Sets source node. If a connection is indirected this node is represented just as one of the connection's end.

Parameters:

node - source node

setTargetNode

void setTargetNode(ISchemaNode node)

Sets target node. If a connection is indirected this node is represented just as one of the connection's end.

Parameters:

node - target node

isDirected

@PropertyGetter(name="DIRECTED",
                type=BOOLEAN,
                matchable=true)
Boolean isDirected()

Indicates if a connections is directed or not.

Returns:

true if connection is directed, false otherwise

getWeight

@TransientProperty(name="WEIGHT",
                   type=INTEGER,
                   matchable=false)
Integer getWeight()

A problem dependent weight.

Returns:

weight of the connection

isBetween

boolean isBetween(ISchemaNode node1,
                  ISchemaNode node2)

Checks if this connection is between two given nodes.

Parameters:

node1 - first node

node2 - second node

Returns:

true if this connection group is between two given nodes
