Querying point hierarchy list from global script

[iperry]

Hi,

I was wondering if there is a function available for querying the point hierarchy from a global script, similar to DataPointQuery?

Also, are there any docs regarding the functions/methods that are available in the global scripts, like DataPointQuery?

Thanks
Ian

Hi Ian,

All the functions that would be available in other scripting environments would be available in the global script environment. For instance

var rootFolders = JSON.parse( JsonEmport.getConfiguration("pointHierarchy") )["pointHierarchy"];
print( rootFolders );

which will export the hierarchy, then parse it into a javascript object. You could manipulate that however you wanted.and reimport with

JsonEmport.doImport( {"pointHierarchy": rootFolders } );

Methods available to JavaScript are most definitively found here: https://github.com/infiniteautomation/ma-core-public/blob/main/Core/web/WEB-INF/dox/mangoJavaScript.htm

Alternatively you could get the PointHierarchy right from the code, then you could use its methods. Like,

function printContextPointPath( cxtPnt ) {
  print( com.serotonin.m2m2.vo.hierarchy.PointHierarchy.getPath( cxtPnt.getDataPointWrapper().getId(), 
         com.serotonin.m2m2.db.dao.DataPointDao.instance.getPointHierarchy( true ).getRoot() ) );
  //# use getPointHierarchy( false ) if you're going to modify it and call the DPD's savePointHierarchy method.
}
printContextPointPath(p);

Methods in point hierarchies and point folders are in these classes: https://github.com/infiniteautomation/ma-core-public/tree/main/Core/src/com/serotonin/m2m2/vo/hierarchy

Great thanks! I will try that out.
