Method Detail

initialize

public void initialize(PegasusBag bag,
                       java.lang.String dax)

The overloaded constructor.

Specified by:

initialize in interface Callback

Parameters:

bag - the bag of initialization objects containing the properties and the logger

dax - the path to the DAX file.

cbDocument

public void cbDocument(java.util.Map attributes)

Callback when the opening tag was parsed. This contains all attributes and their raw values within a map. It ends up storing the attributes with the adag element in the internal memory structure.

Specified by:

cbDocument in interface Callback

Parameters:

attributes - is a map of attribute key to attribute value

cbWfInvoke

public void cbWfInvoke(Invoke invoke)

Callback when a invoke entry is encountered in the top level inside the adag element in the DAX.

Specified by:

cbWfInvoke in interface Callback

Parameters:

invoke - the invoke object

cbJob

public void cbJob(Job job)

Callback for the job from section 2 jobs. These jobs are completely assembled, but each is passed separately.

Specified by:

cbJob in interface Callback

Parameters:

job - the Job object storing the job information gotten from parser.

cbParents

public void cbParents(java.lang.String child,
                      java.util.List parents)

Callback for child and parent relationships from section 3.

Specified by:

cbParents in interface Callback

Parameters:

child - is the IDREF of the child element.

parents - is a list of IDREFs of the included parents.

cbDone

public void cbDone()

Callback when the parsing of the document is done. It sets the flag that the parsing has been done, that is used to determine whether the ADag object has been fully generated or not.

Specified by:

cbDone in interface Callback

getConstructedObject

public java.lang.Object getConstructedObject()

Returns an ADag object corresponding to the abstract plan it has generated. It throws a runtime exception if the method is called before the object has been created fully.

Specified by:

getConstructedObject in interface Callback

Returns:

ADag object containing the abstract plan referred in the dax.

cbCompoundTransformation

public void cbCompoundTransformation(CompoundTransformation compoundTransformation)

Callback when a compound transformation is encountered in the DAX

Specified by:

cbCompoundTransformation in interface Callback

Parameters:

compoundTransformation - the compound transforamtion

cbFile

public void cbFile(ReplicaLocation rl)

Callback when a replica catalog entry is encountered in the DAX

Specified by:

cbFile in interface Callback

Parameters:

rl - the ReplicaLocation object

cbExecutable

public void cbExecutable(TransformationCatalogEntry tce)

Callback when a transformation catalog entry is encountered in the DAX

Specified by:

cbExecutable in interface Callback

Parameters:

tce - the transformationc catalog entry object.
