Class TypeHierarchyNode

Object

kb.hierarchy.POSetNode

kb.hierarchy.TypeHierarchyNode

public class TypeHierarchyNode
extends POSetNode

A node in a type hierarchy graph. The "key" is used to facilitate matching and storing. The value is the original label used for the type. There are two special cases -- both top and bottom are fixed and never keyed.

Constructor Detail

TypeHierarchyNode

public TypeHierarchyNode(String key,
                         String value)

Considers the key to be the node's identity, but keeps the value too.

Parameters:

key - the identity of the node

value - the first value stored with this node.

Method Detail

getKey

public String getKey()

Overrides:

getKey in class POSetNode

getValue

public String getValue()

Get the first value in the list, arbitrarily.

Returns:

the first value in the list

getValues

public ArrayList<String> getValues()

Returns the entire set of values for this particular node.

addValue

public void addValue(String value)

If the value is not already one of the type labels represented in this node, then it's added. This has no effect on the already existing key. If the matching rules were not obeyed, then erroneous values are fair game, since the node itself doesn't know the matching rules used to create it.

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(boolean deep)

Parameters:

deep - Whether to list parent and child nodes recursively or not

Returns:

a human-readable text version of what's in the node
