  uk.ac.ic.doc.automed.reps.Node

public class Node
extends java.lang.Object

Method Summary

Node[]	getAdjacent() Returns all nodes that are adjacent to this node - that is, nodes for which a transformation is defined between its schema and this node's schema.
Node[]	getChildren() If the network this node belongs to is directed then returns all the adjacent nodes that are children of this node, otherwise its behaviour is defined by the type of network but the children will be a subset of adjacent.
Network	getNetwork() Returns the network this node belongs to
static Node	getNode(Schema s) returns the node for a schema if one exists or null otherwise
static Node	getNode(java.lang.String schemaName) returns the node for a schema if one exists or null otherwise
Node[]	getParents() If the network this node belongs to is directed then returns all the adjacent nodes that are parents of this node, otherwise its behaviour is defined by the type of network but the parents will be a subset of adjacent.
Schema	getSchema() Returns the schema at this node in the network
boolean	isAdjacent(Node n)
boolean	isLeaf() True if (and only if) this node belongs to a directed network and this is a leaf node.
boolean	isRoot() True if (and only if) this node belongs to a directed network and this is a root node.
java.lang.String	toString()

Method Detail

getNode

public static Node getNode(java.lang.String schemaName)

returns the node for a schema if one exists or null otherwise

getNode

public static Node getNode(Schema s)

returns the node for a schema if one exists or null otherwise

getSchema

public Schema getSchema()

Returns the schema at this node in the network

getNetwork

public Network getNetwork()

Returns the network this node belongs to

isRoot

public boolean isRoot()

True if (and only if) this node belongs to a directed network and this is a root node.

isLeaf

public boolean isLeaf()

True if (and only if) this node belongs to a directed network and this is a leaf node.

getParents

public Node[] getParents()

If the network this node belongs to is directed then returns all the adjacent nodes that are parents of this node, otherwise its behaviour is defined by the type of network but the parents will be a subset of adjacent. Note that you can do what you want with the array returned, it is created on each invocation and is not backed by the network or the repository in any way.

getChildren

public Node[] getChildren()

If the network this node belongs to is directed then returns all the adjacent nodes that are children of this node, otherwise its behaviour is defined by the type of network but the children will be a subset of adjacent. Note that you can do what you want with the array returned, it is created on each invocation and is not backed by the network or the repository in any way.

getAdjacent

public Node[] getAdjacent()

Returns all nodes that are adjacent to this node - that is, nodes for which a transformation is defined between its schema and this node's schema. Note that you can do what you want with the array returned, it is created on each invocation and is not backed by the network or the reposistory in any way.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isAdjacent

public boolean isAdjacent(Node n)
