| Node | | public class Node implements Serializable(Code) | | The Node class represents a node in a directed graph.
A directed graph is used to represent a workflow model.
|
| Node | | public Node(int nodeId)(Code) | | Constructs a new node
int nodeId |
| addDestination | | public void addDestination(Node node, String rule)(Code) | | Adds a destination and a rule to evaluate a workflowobject's
transition to this destination.
Parameters:
Node - node The destination node
Parameters:
String - rule The rule for reaching this destination |
| addFromNode | | public void addFromNode(Node n)(Code) | | Adds a fromNode to this node
Parameters:
Node - node The from node |
| detectCycle | | public boolean detectCycle()(Code) | | Detects if the graph contains cycles.
|
| expand | | public void expand(int gid, Connection con)(Code) | | Recursively loads this node and all nodes reachable from this node
from database.
int gid The graph ID |
| getContainee | | public String getContainee()(Code) | | Returns the node's containee graph name. Only valid if node's type is CONTAINER
containee |
| getContaineeVersion | | public int getContaineeVersion()(Code) | | Returns the node's containee graph version. Only valid if node's type is CONTAINER
containeeVersion |
| getDescription | | public String getDescription()(Code) | | Returns node description
description |
| getDestinations | | public Vector getDestinations()(Code) | | Vector - this node's list of destinations |
| getFromNodes | | public Vector getFromNodes()(Code) | | Vector - this node's list of from nodes |
| getNode | | public Node getNode(int nodeId)(Code) | | Finds and returns a node within a graph given a node ID
int nodeId The node ID for finding Node the result, null if not found |
| getNode | | public Node getNode(String name)(Code) | | Finds and returns a node within a graph given a node name
Parameters:
String - name The node name for finding Node the result, null if not found |
| getNodeId | | public int getNodeId()(Code) | | Returns the node ID
int nodeId |
| getNodeIdAsInteger | | public Integer getNodeIdAsInteger()(Code) | | Returns the node ID
Integer nodeId |
| getNodeName | | public String getNodeName()(Code) | | Returns the node name
String node name |
| getNodeType | | public String getNodeType()(Code) | | Returns the node type
String node type |
| getNodes | | public Vector getNodes(String nodeType)(Code) | | Vector - all descendant nodes of specified type |
| getNodes | | public Vector getNodes()(Code) | | Vector - all descendant nodes |
| getProperty | | public Object getProperty(String key)(Code) | | Gets a node's property
Parameters:
key - the property name the property value |
| getTimeoutHandler | | public String getTimeoutHandler()(Code) | | Gets the timeout handler for a Process node
the timeout handler name |
| getTimeoutMinutes | | public int getTimeoutMinutes()(Code) | | Gets the timeout for a Process node
the timeout in minutes |
| print | | public void print()(Code) | | Prints out node id and description of node.
Useful for debugging.
|
| saveDB | | public void saveDB(int gid, Connection con)(Code) | | Recursively saves a node, its destinations and all links
between nodes to the database.
int gid The graph ID |
| setContainee | | public void setContainee(String graphName)(Code) | | Sets the node's containee graph name. Only valid if node's type is CONTAINER
Parameters:
String - grapghName |
| setContaineeVersion | | public void setContaineeVersion(int i)(Code) | | Sets the node's containee graph version. Only valid if node's type is CONTAINER
