Constructor Detail

XMLTransformer

public XMLTransformer(Schema source,
                      org.w3c.dom.Document sourceSchemaUIDDoc,
                      Schema target,
                      org.w3c.dom.Document targetSchemaUIDDoc,
                      boolean createSyntheticData)

Parameters:

source - the source AutoMed XMLDSS

target - the target AutoMed XMLDSS

Method Detail

transform

public void transform(boolean validateSource,
                      boolean validateTarget)

Creates the transformation pathway from the source to the target schema. The whole process can be divided into four steps:
- Growing phase: insert schema objects to the source schema
- Shrinking phase: remove schema objects from the source schema
- Renaming phase: rename edge labels so that the ordering they represent is correct
- Check transformation: check that the transformation result is correct

Parameters:

validateSource - if true, validate source DOM XMLDSS against any referenced DTD/XML Schema

validateTarget - if true, validate target DOM XMLDSS against any referenced DTD/XML Schema

getFinalDoc

public org.w3c.dom.Document getFinalDoc()

Returns:

the DOM representation of the transformed XMLDSS.

getFinalSchemaName

public java.lang.String getFinalSchemaName()

Returns:

the name of the transformed XMLDSS.

getFinalSchema

public Schema getFinalSchema()

Returns:

the transformed AutoMed XMLDSS schema.

listTransformationPathway

public void listTransformationPathway()

Prints out the transformation pathway created by the schema transformation algorithm.

UIDRemoveSchemaName

protected java.lang.String UIDRemoveSchemaName(java.lang.String uid)

UIDRemoveSchemaName

protected java.lang.String UIDRemoveSchemaName(org.w3c.dom.Node elem)
