Enclosing class:

SingleLook

private class SingleLook.MyCallBackHandler
extends Object
implements org.griphyn.vdl.euryale.Callback

The internal callback handler for the DAXParser in Euryale. It stores all the jobs making up the dax in an internal map, which is then referred to get the job information for the jobs making up the partition.

Constructor Summary

SingleLook.MyCallBackHandler()
The empty constructor.

Method Summary

void	cb_document(Map attributes) Callback when the opening tag was parsed.
void	cb_done() Callback when the parsing of the document is done.
void	cb_filename(org.griphyn.vdl.dax.Filename filename) Callback for the filename from section 1 filenames.
void	cb_job(org.griphyn.vdl.dax.Job job) Callback for the job from section 2 jobs.

Method Detail

cb_document

public void cb_document(Map attributes)

Callback when the opening tag was parsed. The attribute maps each attribute to its raw value. The callback initializes the DAG writer.

Specified by:

cb_document in interface org.griphyn.vdl.euryale.Callback

Parameters:

attributes - is a map of attribute key to attribute value

cb_filename

public void cb_filename(org.griphyn.vdl.dax.Filename filename)

Callback for the filename from section 1 filenames. Does nothing as the filenames for the partitioned dax are constructed from the jobs.

Specified by:

cb_filename in interface org.griphyn.vdl.euryale.Callback

Parameters:

filename - is a DAX-style filename elements.

cb_job

public void cb_job(org.griphyn.vdl.dax.Job job)

Callback for the job from section 2 jobs. This ends up storing all the jobs in the memory to be used for writing out the partition dax.

Specified by:

cb_job in interface org.griphyn.vdl.euryale.Callback

Parameters:

job - the object containing the job information.

cb_parents

public void cb_parents(String child,
                       List parents)

Callback for child and parent relationships from section 3. This is an empty implementation, as the Partition object contains the relations amongst the jobs making up the partition.

Specified by:

cb_parents in interface org.griphyn.vdl.euryale.Callback

Parameters:

child - is the IDREF of the child element.

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

cb_done

public void cb_done()

Callback when the parsing of the document is done. While this state could also be determined from the return of the invocation of the parser, that return may be hidden in another place of the code. This callback can be used to free callback-specific resources.

Specified by:

cb_done in interface org.griphyn.vdl.euryale.Callback
