Download the following libraries into a folder of your system:

Since the server at baco computer uses an older version, if you are planing on accessing it server, you should download this version of SDAS Core Libraries and Client:

SDAS Core Libraries
SDAS Client

If you are using a different server, download these instead:

SDAS Core Libraries
SDAS Client

Add the SDAS libraries to the octave classpath

These example assume that you have saved all the jar files in the folder /home/user/sdas/

javaaddpath("/home/user/sdas/SDAS.jar")
javaaddpath("/home/user/sdas/SDASClient.jar")
javaaddpath("/home/user/sdas/commons-codec-1.3.jar")
javaaddpath("/home/user/sdas/xmlrpc-2.0.jar")

Beware that on Windows you must use / instead of the regular \. If you have saved all the jar files in the folder C:\sdas\, for example:

javaaddpath("C:/sdas/SDAS.jar")
javaaddpath("C:/sdas/SDASClient.jar")
javaaddpath("C:/sdas/commons-codec-1.3.jar")
javaaddpath("C:/sdas/xmlrpc-2.0.jar")

Get a connection to the sdas server

client = javaObject("org.sdas.core.client.SDASClient", "baco.ipfn.ist.utl.pt", 8888);

Search events

found = client.searchDeclaredEventsByName('S');

found = client.searchDeclaredEventsByName('SHOTS');

found = client.searchDeclaredEventsByName('SHOT', 'en');

found = client.searchDeclaredEventsByUniqueID('0x0000SHOT', 'en');

found = client.searchDeclaredEventsByDescription('ShotSHOT');

found = client.searchDeclaredEventsByDescription('ShotSHOT', 'en');

for i=1:1:size(found)
    found(i).toString
end

max = client.searchMaxEventNumber('0x0000')

min = client.searchMinEventNumber('0x0000')

Search events in a time window

NOTE: You can construct time with a resolution of picosseconds, just add to the example values for millis, micros, nanos and picos
NOTE 2: Date constructors have the months index to 0 (January is 0 and December is 11)

Search events in December 2005:

date_start = javaObject("org.sdas.core.time.Date", 2005, 11, 1);
date_end =  javaObject("org.sdas.core.time.Date", 2005, 11, 31);
tstart =  javaObject("org.sdas.core.time.TimeStamp", date_start);
tend =  javaObject("org.sdas.core.time.TimeStamp", date_end);
eventsFound = client.searchEventsByEventTimeWindow(tstart, tend);
for i = 1:1:size(eventsFound)
    eventsFound(i).toString
end

Search events in the 22 December 2005 between 5pm and 6pm:

date_start = javaObject("org.sdas.core.time.Date", 2005, 11, 22);
date_end = javaObject("org.sdas.core.time.Date", 2005,11,22);
time_start = javaObject("org.sdas.core.time.Time", 17, 0, 0);
time_end = javaObject("org.sdas.core.time.Time", 18, 0, 0);
tstart = javaObject("org.sdas.core.time.TimeStamp", date_start, time_start);
tend = javaObject("org.sdas.core.time.TimeStamp", date_end, time_end);
eventsFound = client.searchEventsByEventTimeWindow(tstart, tend);
for i = 1:1:size(eventsFound)
    eventsFound(i).toString
end

Search parameters

parametersFound = client.searchParametersByName('DENS');

parametersFound = client.searchParametersByName('DENS', 'pt');

parametersFound = client.searchParametersByUniqueID('DENS');

parametersFound = client.searchParametersByDescription('current');


for i = 1:1:size(parametersFound)
    parametersFound(i).toString
end

Search data

This function returns the parameters unique identifiers where the data isn’t null for the selected event:

dataFound = client.searchDataByEvent('0x0000', 17898);
for i = 1:1:size(dataFound)
    dataFound (i)
end

Get data

NOTE: The unique identifiers are CASE-SENSITIVE

The returned data structure gives you information about:

start time
end time
time of the event
mime_type
the parameter unique identifier

Data for only one parameter

dataStructArray=client.getData('POST.PROCESSED.DENSITY','0x0000', 17898)
dataStruct=dataStructArray(1);
dens=dataStruct.getData;
for i=1:length(dens)
density(i)=dens(i);
end
tstart = dataStruct.getTStart;
tend = dataStruct.getTEnd;

Calculate the time between samples

tbs= (tend.getTimeInMicros - tstart.getTimeInMicros)/length(density);

Get the events associated with this data

events = dataStruct.getEvents;

The event time (I’m assuming the event I want is at the index 0, but I should check first...)

tevent = events(1).getTimeStamp;

The delay of the start time relative to the event time

delay = tstart.getTimeInMicros - tevent.getTimeInMicros

Finally create the time array

times = delay:tbs:delay+tbs*(length(density)-1);

And plot the data

plot(times, density);

Data for several parameters in the same event

dataStruct=client.getMultipleData({'POST.PROCESSED.DENSITY', 'POST.PROCESSED.IPLASMA'},'0x0000', 17898)
dataStructDens=dataStruct(1,1);
dataStructIP=dataStruct(2,1);
dens=dataStructDens.getData(); 
ip=dataStructIP.getData();

Data for several parameters in different events

dataStruct=client.getMultipleData({'POST.PROCESSED.DENSITY', 'POST.PROCESSED.IPLASMA'},{'0x0000','0x0000'}, [17898,17899])
dataStructDens=dataStruct(1,1);
dataStructIP=dataStruct(2,1);
dens=dataStructDens.getData(); 
ip=dataStructIP.getData();

Data for the same parameter in different events

dataStruct=client.getMultipleData('POST.PROCESSED.DENSITY',{'0x0000','0x0000'}, [17898,17899])
dataStructDens=dataStruct(1,1);
dataStructIP=dataStruct(2,1);
dens=dataStructDens.getData(); 
ip=dataStructIP.getData();

Data for the same parameter in different event numbers

dataStruct=client.getMultipleData('POST.PROCESSED.DENSITY', '0x0000', [17898,17899])

More example code is available on the Octave Code page.
