marklogic - Dynamic options via client-java-api -


i creating rest webservice take parameters via url , search in marklogic based on these dynamic parameters.

q=search&offset=0&limit=10& sort=documentid|asc&termaggregations=group:10

i creating using structuredquerydefinition & rawcombinedquerydefinition :

structuredquerydefinition querycriteria = sqb.or(query, sqb.properties(sqb.term(parameters.getquery)))); string combinedquery = "<search xmlns=\"http://marklogic.com/appservices/search\">"             + querycriteria.serialize() + options + "</search>"; rawcombinedquerydefinition rawcombinedquery = querymgr.newrawcombinedquerydefinition( new stringhandle(combinedquery));

for creating query options, using string /string buffer option extract-document-data 

extracteddataoption.append("<extract-document-data selected=\"include\">") loop through each field   {   extracteddataoption.append("<extract-path ");     extracteddataoption.append(" xmlns:");     extracteddataoption.append(field_attributes.get("namespace"));     extracteddataoption.append(" >//");     extracteddataoption.append(field_attributes.get("fieldname"));     extracteddataoption.append(" </extract-path>"); }    extracteddataoption.append("</extract-document-data>");

similarly sort, facets, filters constraints.

i can't use persisted query parameters sort, facets & filters based on webservice request parameters.

also, see queryoptionsbuilder , other similar classes deprecated.

can please let me best way create these different options dynamically instead of string?

thanks

strings work fine when options simple or static. if you're building complex or dynamic xml structure think you're wise seek less accidentally produce mal-formed xml. xml builder libraries java prevalent , several ones directly supported java client api: jackson, jdom, dom4j, xom, dom, , jaxb. pick favorite.

also, there xml builders create inputstream or string , can supported using stringhandle or inputstreamhandle.

here's example of using xmlstreamwriter build options xml serialize string (cobled pieces in combinedquerybuildertest.java).

    bytearrayoutputstream baos = new bytearrayoutputstream();     xmloutputfactory factory = xmloutputfactory.newinstance();     factory.setproperty(xmloutputfactory.is_repairing_namespaces, true);      xmlstreamwriter writer = factory.createxmlstreamwriter(out, "utf-8");     writer.setdefaultnamespace("http://marklogic.com/appservices/search");     writer.writestartelement("options");         writer.writestartelement("search-option");             writer.writecharacters("filtered");         writer.writeendelement();     writer.writeendelement();     return baos.tostring("utf-8");

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
