public abstract class AbstractModule
extends java.lang.Object

The AbstractModule class represents an abstract schema matching module. A schema mathing module can compare SchemaElement objects and produce bidirectional degrees for each pair of schema elements. The module stores SchemaElementPair objects and their associated SimilarSchemaElementPair objects.

Method Detail

setUSRs

public void setUSRs(UncertainSchemaElementPair[] usrs)

getUSRs

public UncertainSchemaElementPair[] getUSRs()

setBidirectionalDegrees

public void setBidirectionalDegrees(java.util.Hashtable forward,
                                    java.util.Hashtable backward)

Sets the bidirectional degrees of the module. The arguments are hash tables with the forward and backward similarity degrees. The hash tables associate SchemaElementPair objects to SimilarSchemaElementPair objects.

Parameters:

forward - the forward similarity degrees

backward - the backward similarity degrees

getBidirectionalDegrees

public static java.util.Hashtable getBidirectionalDegrees(java.util.Hashtable forward,
                                                          java.util.Hashtable backward)

Returns a Hashtable of the bidirectional degrees. The hash table has keys SchemaElementPair objects which are associated with SimilarSchemaElementPair objects, which provide the bidirectional degrees.

Returns:

a Hashtable of the bidirectional degrees

getBidirectionalDegrees

public SimilarSchemaElementPair[] getBidirectionalDegrees()

Returns an array of SimilarSchemaElementPair objects which define the bidirectional degrees between the pairs of schema elements.

Returns:

an array of SimilarSchemaElementPair object with the bidirectional degrees of schema elements

getBidirectionalSimilarity

public SimilarSchemaElementPair getBidirectionalSimilarity(SchemaElementPair p)

Returns a SimilarSchemaElementPair object which defines the bidirectional degrees for the specified SchemaElementPair

Parameters:

p - the schema element pair whose bidirectional degrees are returned

Returns:

a SimilarSchemaElementPair object with the bidirectional degrees of the SchemaElementPair
