Interface Hierarchical<O>

Type Parameters:

O - Object type in hierarchy

All Known Implementing Classes:

Cluster

public interface Hierarchical<O>

Interface for objects with an internal hierarchy interface. Note that the object can chose to delegate the hierarchy to an external hierarchy.

Method Summary

List<O>	getChildren() Get children list.
List<O>	getParents() Get parents list.
boolean	isHierarchical() Test for hierarchical properties
IterableIterator<O>	iterAncestors() Iterate ancestors (recursive parents)
IterableIterator<O>	iterDescendants() Iterate descendants (recursive children)
int	numChildren() Get number of children
int	numParents() Get number of parents

Method Detail

isHierarchical

boolean isHierarchical()

Test for hierarchical properties

Returns:

hierarchical data model.

numChildren

int numChildren()

Get number of children

Returns:

number of children

getChildren

List<O> getChildren()

Get children list. Resulting list MAY be modified. Result MAY be null, if the model is not hierarchical.

iterDescendants

IterableIterator<O> iterDescendants()

Iterate descendants (recursive children)

Returns:

iterator for descendants

numParents

int numParents()

Get number of parents

Returns:

number of parents

getParents

List<O> getParents()

Get parents list. Resulting list MAY be modified. Result MAY be null, if the model is not hierarchical.

Returns:

list of parents

iterAncestors

IterableIterator<O> iterAncestors()

Iterate ancestors (recursive parents)

Returns:

iterator for ancestors
