Class NodeID

java.lang.Object
  org.knime.core.node.workflow.NodeID

All Implemented Interfaces:

Comparable<NodeID>

public class NodeID
extends Object
implements Comparable<NodeID>

Holds hierarchical ID of a node. The hierarchy models nested meta nodes. All IDs will have one static instance of ROOTID as their top ID in this hierarchy.

Author:

M. Berthold/B. Wiswedel, University of Konstanz

Field Summary

(package private) static NodeID

ROOTID

Constructor Summary

NodeID(int ix)
Creates top level NodeID object.

NodeID(NodeID prefix, int ix)
Creates now NodeID object based on a predefined prefix (usually the ID of the encapsulating project or metanode) and the node's ID itself.

Method Summary

int	compareTo(NodeID o)
boolean	equals(Object obj)
String	getIDWithoutRoot()
int	getIndex()
NodeID	getPrefix()
int	hashCode()
boolean	hasPrefix(NodeID prefix) Checks for matching prefix (this node prefix can be longer, though).
boolean	hasSamePrefix(NodeID prefix) Checks for exact matching prefixes.
String	toString() Returns on string representation of index.

Constructor Detail

NodeID

public NodeID(NodeID prefix,
              int ix)

Creates now NodeID object based on a predefined prefix (usually the ID of the encapsulating project or metanode) and the node's ID itself.

Parameters:

prefix - of ID

ix - itself

NodeID

public NodeID(int ix)

Creates top level NodeID object.

Parameters:

ix - itself

Method Detail

getPrefix

public NodeID getPrefix()

Returns:

prefix of this node's ID.

getIndex

public int getIndex()

Returns:

index of this node (without prefix!).

getIDWithoutRoot

hasSamePrefix

public boolean hasSamePrefix(NodeID prefix)

Checks for exact matching prefixes.

Parameters:

prefix - to check

Returns:

true if prefix are the same

hasPrefix

public boolean hasPrefix(NodeID prefix)
