org.autoplot.pds.Pds3DataSource
PDS4 file source. This is pointed at PDS4 xml files and will return data
they describe.
getDataSet
getDataSet( ProgressMonitor mon ) → QDataSet
Parameters
mon - a ProgressMonitor
Returns:
org.das2.qds.QDataSet

getDataSetFromBundle
getDataSetFromBundle( org.w3c.dom.Document doc, ProgressMonitor mon ) → QDataSet
given the bundle, figure out which files should be loaded to implement the time range. This will call recursively
into this code for each item. This unimplemented stub returns an empty dataset.
//TODO: implement me
Parameters
doc - the xml document
mon - progress monitor
Returns:
rank 0 stub

getDataSetFromCollection
getDataSetFromCollection( org.w3c.dom.Document doc, ProgressMonitor mon ) → QDataSet
given the collection, figure out which files should be loaded to implement the time range. This will call recursively
into this code for each item. This unimplemented stub returns an empty dataset.
//TODO: implement me
Parameters
doc - the xml document
mon - progress monitor
Returns:
rank 0 stub

resolveIndependentAxis
resolveIndependentAxis( org.w3c.dom.Document doc, String axisName ) → String
return the name of the independent parameter that works in this axis.
This currently assumes the first node with this axisName is the
independent axis.
For example, with https://space.physics.uiowa.edu/voyager/data/voyager-2-pws-wf/data/1987/vg2_pws_wf_1987-04-21T17_v1.0.xml,
if axisName=='time' then the result will be "Epoch"
This shows where this logic fails:

For this file, I had to kludge in a test for the pitch angles.
Parameters
doc - the xml document
axisName - the axis name
Returns:
null or the independent variable for the axis.

seekDependencies
seekDependencies( org.w3c.dom.Document doc, java.util.List depend ) → List
look through the PDS label document to see if dependencies can be
identified. Presently, this is simply one other dataset with the
same axis (as in sample_offset) or the same axis name as something
that has a time unit (Epoch).
Parameters
doc - the parsed document for the label XML
depend - the name of the data for the dependent variable, e.g. Waveform
Returns:
( Epoch, sample_offset, Waveform )
