Interface HierarchyManager.InterEdgeData

Enclosing class:

HierarchyManager

public static interface HierarchyManager.InterEdgeData

Specifies the general contract for storing and retrieving additional data for inter-edges.

Field Summary

static java.lang.String	SOURCE_PORT_KEY Key for storing mappings of nodes to node ports.
static java.lang.String	TARGET_PORT_KEY Key for storing mappings of nodes to node ports.

Method Summary

java.lang.Object	get(java.lang.String key) Returns the value that has been stored for the specified key.
Node	getRealSource() Returns the real source node of the inter-edge to which this data object is associated.
Node	getRealTarget() Returns the real target node of the inter-edge to which this data object is associated.
java.lang.Object	put(java.lang.String key, java.lang.Object value) Stores the specified value using the specified lookup key.
java.lang.Object	remove(java.lang.String key) Removes the key-value pair for the specified key.

Field Detail

SOURCE_PORT_KEY

static final java.lang.String SOURCE_PORT_KEY

Key for storing mappings of nodes to node ports. Values have to be instances of Map. The stored mappings are used to bind inter edges to source node ports whenever an endpoint of an inter edge is changed due to a group being closed or a folder being opened.

Constant Field Values

TARGET_PORT_KEY

static final java.lang.String TARGET_PORT_KEY

Key for storing mappings of nodes to node ports. Values have to be instances of Map. The stored mappings are used to bind inter edges to target node ports whenever an endpoint of an inter edge is changed due to a group being closed or a folder being opened.
