Interface NodeCollection

All Superinterfaces:: java.io.Serializable

All Known Implementing Classes:: ProcessDefinition, SuperState

public interface NodeCollection
extends java.io.Serializable
extends java.io.Serializable

is a common supertype for a ProcessDefinition and a SuperState.

Method Summary

Node addNode(Node node)
          adds the given node to this node-collection.

Node findNode(java.lang.String hierarchicalName)
          finds the node by the given hierarchical name.

java.lang.String generateNodeName()
          generates a new name for a node to be added to this collection.

Node getNode(java.lang.String name)
          retrieves a node by name.

java.util.List getNodes()
          is the ordered list of nodes.

java.util.Map getNodesMap()
          maps node-names to nodes.

boolean hasNode(java.lang.String name)
          is true if this node-collection contains a node with the given name, false otherwise.

Node removeNode(Node node)
          removes the given node from this node-collection.

void reorderNode(int oldIndex, int newIndex)
          changes the order of the nodes : the node on oldIndex is removed and inserted in the newIndex.

Method Summary
`Node`	`addNode(Node node)` adds the given node to this node-collection.
`Node`	`findNode(java.lang.String hierarchicalName)` finds the node by the given hierarchical name.
`java.lang.String`	`generateNodeName()` generates a new name for a node to be added to this collection.
`Node`	`getNode(java.lang.String name)` retrieves a node by name.
`java.util.List`	`getNodes()` is the ordered list of nodes.
`java.util.Map`	`getNodesMap()` maps node-names to nodes.
`boolean`	`hasNode(java.lang.String name)` is true if this node-collection contains a node with the given name, false otherwise.
`Node`	`removeNode(Node node)` removes the given node from this node-collection.
`void`	`reorderNode(int oldIndex, int newIndex)` changes the order of the nodes : the node on oldIndex is removed and inserted in the newIndex.

Method Detail

getNodes

java.util.List getNodes()

is the ordered list of nodes.

getNodesMap

java.util.Map getNodesMap()

maps node-names to nodes. returns an empty map if no nodes are contained.

getNode

Node getNode(java.lang.String name)

retrieves a node by name.

Returns:: the node or null if no such node is present.

hasNode

boolean hasNode(java.lang.String name)

is true if this node-collection contains a node with the given name, false otherwise.

addNode

Node addNode(Node node)

adds the given node to this node-collection.

Returns:: the added node.
Throws:: java.lang.IllegalArgumentException - if node is null.

removeNode

Node removeNode(Node node)

removes the given node from this node-collection.

Returns:: the removed node or null if the node was not present in this collection.
Throws:: java.lang.IllegalArgumentException - if node is null or if the node is not contained in this nodecollection.

reorderNode

void reorderNode(int oldIndex,
                 int newIndex)

changes the order of the nodes : the node on oldIndex is removed and inserted in the newIndex. All nodes inbetween the old and the new index shift one index position.

Throws:: java.lang.IndexOutOfBoundsException

generateNodeName

java.lang.String generateNodeName()

generates a new name for a node to be added to this collection.

findNode

Node findNode(java.lang.String hierarchicalName)

finds the node by the given hierarchical name. use .. for the parent, use slashes '/' to separate the node names.
