Method Summary

Node	findNode(String nodeName) searches for the given node in this node, including this node and all child nodes recursively.
Node	getNode(String nodeName) the first composite node with the given name or null of no such node exists.
List<Node>	getNodes() the list of composite nodes.
Map<String,Node>	getNodesMap() the composite nodes, keyed by node name.
boolean	hasNode(String nodeName) indicates if a node with the given name exists in this processDefinition.
boolean	hasNodes() indicates if this processDefinition has nodes.

Method Detail

hasNodes

boolean hasNodes()

indicates if this processDefinition has nodes.

getNodes

List<Node> getNodes()

the list of composite nodes. Beware: the actual member is returned. No copy is made.

hasNode

boolean hasNode(String nodeName)

indicates if a node with the given name exists in this processDefinition.

getNode

Node getNode(String nodeName)

the first composite node with the given name or null of no such node exists.

findNode

Node findNode(String nodeName)

searches for the given node in this node, including this node and all child nodes recursively. The search is done depth-first. A null value for nodeName matches a node without a name.

getNodesMap

Map<String,Node> getNodesMap()

the composite nodes, keyed by node name. If a node with the same name occurs mutltiple times, the first in the list is included in the map. Nodes with a null value for their name are not included in the map. Beware: the actual member is returned. No copy is made. In fact, the returned map is maintained as a cache. So updates to the map will influence subsequent retrievals of nodes by name.
