Method Detail

initialize

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

The overloaded constructor.

Specified by:

initialize in interface Callback

Overrides:

initialize in class DAX2Graph

Parameters:

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

dax - the path to the DAX file.

setLabelKey

public void setLabelKey(java.lang.String key)

Set the profile key that is to be used to pick up the labels. Sets the profile key to the value specified. If value passed is null, then is set to the default label key.

Parameters:

key - the VDS profile key that is to be used.

DEFAULT_LABEL_KEY

cbJob

public void cbJob(Job job)

This constructs a graph node for the job and ends up storing it in the internal map. In addition assigns a label with the node. The label is is the value of a profile in the VDS namespace. The name of the profile can

Specified by:

cbJob in interface Callback

Overrides:

cbJob in class DAX2Graph

Parameters:

job - the job that was parsed.

cbDone

public void cbDone()

Callback to signal that traversal of the DAX is complete. At this point a dummy root node is added to the graph, that is the parents to all the root nodes in the existing DAX. This method in additions adds the default label to the root.

Specified by:

cbDone in interface Callback

Overrides:

cbDone in class DAX2Graph
