findAllPaths

public static TransformationPathway[] findAllPaths(java.lang.String schema1,
                                                   java.lang.String schema2)
                                            throws IntegrityException

IntegrityException

findAllPathsToSchema

public static TransformationPathway[] findAllPathsToSchema(java.lang.String schema)
                                                    throws NotFoundException

NotFoundException

findPathFromClosestExtSchema

public static TransformationPathway findPathFromClosestExtSchema(java.lang.String schema)
                                                          throws NotFoundException,

NotFoundException

IntegrityException

findShortestPath

public static TransformationPathway findShortestPath(java.lang.String schema1,
                                                     java.lang.String schema2)
                                              throws NotFoundException

NotFoundException

findShortestPath

public static TransformationPathway findShortestPath(Schema schema1,
                                                     Schema schema2)
                                              throws NotFoundException

Find the shortest path containing the fewest number of steps between two schemas. Note that this might not be the best path to use, since it might contain extend and contract transformations, where a longer path might not contain extend and contract transformations.

NotFoundException

isWellformed

public boolean isWellformed()

IntegrityException

getTransformations

public Transformation[] getTransformations()

Return as an array the Transformations that make up this TransformationPathway.

getSchemas

public Schema[] getSchemas()

Return as an array the Schemas that appear in the Transformations of this TransformationPathway.

numOfTrans

IntegrityException

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

write

public void write()

Write out the series of transformations found in this pathway to the standard output in a human readable form
