I use pega.desktop.openAssignment to open assignment, i cannot find documentation about this function

pega.desktop.openAssignment("ASSIGN-WORKLIST FECREDIT-BASE-CA-WORK-COLLECTION C-22982013!FIELDVISIT","","","","true")

from javascript, function use 7 arguments

pega.desktop.openAssignment = function(a, b, c, g, h, e, d) {     e = a;     var f = null;     pega && pega.ui && pega.ui.statetracking && pega.ui.statetracking.setPALInteraction("abc?\x26action\x3dopenAssignment\x26key\x3d" + a);     "object" == typeof e && "safeURL" == e.name && (f = SafeURL_clone(e),     a = f.get("key"),     b = f.get("contentID"),     c = f.get("dynamicContainerID"));     f || (f = new SafeURL);     null != c && "" != c && f.put("dynamicContainerID", c);     null != b && "" != b && f.put("contentID", b);     null != h && f.put("SkipConflictCheck", h);     pega.desktop.augmentConfigParams(d, f);     pega.desktop.support.handleMultipleAG(a, !0, void 0, f) && pega.desktop.support.postOpenAssignment(a, g, f) }

I only know 1st argument is assigment key, please help me clarify other arguments
