Constructor Detail

GraphPath

public GraphPath(OlapTree tree,
                 edu.uci.ics.jung.graph.Vertex mTo)

Minimal constructor

Parameters:

tree - OlapTree class

mTo - destination vertex

GraphPath

public GraphPath(OlapTree tree,
                 List<edu.uci.ics.jung.graph.Vertex> preds,
                 edu.uci.ics.jung.graph.Vertex mTo)

Default constructor

Parameters:

tree - OlapTree class

preds - vertexes from root vertex to destination vertex sorted in order

mTo - destination vertex

Method Detail

getEdges

public List<edu.uci.ics.jung.graph.Edge> getEdges()

Returns:

list of edges on the path

getVertexTo

public edu.uci.ics.jung.graph.Vertex getVertexTo()

Returns:

destination vertex

getOriginalVertexTo

public edu.uci.ics.jung.graph.Vertex getOriginalVertexTo()

In case that this path belongs to datamart, function returns destination vertex in original tree. Otherwise it returns destination vertex, which belongs to current Olap tree.

Returns:

Destination vertex from original tree (if exists). Otherwise is result same like from getVertexTo method

getPreds

public List<edu.uci.ics.jung.graph.Vertex> getPreds()

Returns:

vertexes from root vertex to destination vertex sorted in order

getRoot

public edu.uci.ics.jung.graph.Vertex getRoot()

Returns:

root vertex which belongs to current olap tree

getName

public String getName()

Returns:

name compound from path edge names

getOriginalEdges

public List<edu.uci.ics.jung.graph.Edge> getOriginalEdges()

In case that this path belongs to datamart, function returns list of edges in original tree. Otherwise it returns same result like method getEdges

Returns:

list of original edges
