Class ObserveScriptBuilder

java.lang.Object
  edu.nrao.sss.model.project.AbstractScheduleIterator
      edu.nrao.sss.model.project.ObserveScriptBuilder

public class ObserveScriptBuilder
extends AbstractScheduleIterator

This class provides methods for converting a scheduling block to a Jython Observe Script for the EVLA Monitor and Control system.

This class expects the M&C system to provide the generated script with this set of header code:

 from edu.nrao.evla.observe import Array
 from edu.nrao.evla.observe import Antenna
 from edu.nrao.evla.observe import LoIfSetup
 from edu.nrao.evla.observe import VLALoIfSetup
 from edu.nrao.evla.observe import Source
 from edu.nrao.evla.observe import Subarray
 from edu.nrao.evla.observe import Fringefinders
 from edu.nrao.evla.observe import VlaCorrelatorSetup
 from edu.nrao.evla.observe import Intention
 from edu.nrao.evla.observe import AzElInterferometerModel
 

as well as defining the array and subarray variables to point at appropriate edu.nrao.evla.observe.Array and edu.nrao.evla.observe.Subarray java objects.

The scripts generated by this class will also depend on standard helper scripts being available at /home/mchost/evla/include. Specifically:

Script	Use
focus.py
nodder.py
nod.py
onsource.py
pointCycle.py
point.py
printers.py
radecname.py
raster.py
refPoint.py
sdvlbi.py
tip.py
tmjd.py

Method Detail

toScript

public String toScript(SchedulingBlock sb)
                throws ValidationException

Returns:

getScriptAsStringBuilder(sb).toString().

Throws:

ValidationException

toScript

public String toScript(SchedulingBlock sb,
                       Date start)
                throws ValidationException

Returns:

getScriptAsStringBuilder(sb, start).toString().

Throws:

ValidationException

getScriptAsStringBuilder

public StringBuilder getScriptAsStringBuilder(SchedulingBlock sb)
                                       throws ValidationException

Returns:

a StringBuilder holding python code that will carry out instructions represented by sb. The python code will calculate all source positions and scan start times using startTime as a reference.

Throws:

ValidationException

getScriptAsStringBuilder

public StringBuilder getScriptAsStringBuilder(SchedulingBlock sb,
                                              Date start)
                                       throws ValidationException

If start != null, override the SB's start time to be start even if sb is supposed to be dynamically scheduled. NOTE: in the event that sb is dynamic, a dynamic schedule is still generated, but start is used to calculate all slew times.

Throws:

ValidationException
