java - Z3: ParseSMTLIB2File/String -


i used parsesmtlib2file parse smt2 file context.smt2 has declarations of datatypes, constants, , functions; e.g.

    ; sort declarations     (declare-sort tla_sort_str)     (declare-const x tla_sort_str)     (declare-const y tla_sort_str)     (declare-const z tla_sort_str)

and then, used parsesmtlib2string parse string "(assert (= x y))". following code:

     boolexpr expr = ctx.parsesmtlib2file("context.smt2", null, null, null, null);      string str = "(assert (= x y))";      boolexpr assert = ctx.parsesmtlib2string(str, null, null, null, null);

unfortunately, received error. guess reason ctx doesn't know tla_sort_str, x , y are. if no, how can pass information in context.smt2 parsesmtlib2string? thank much.

that's 'null' arguments (one of them supply sorts have been constructed earlier).

not parsesmtlib2file not support features of smt2 or extensions. read assertions , ignore else, possibly including sort declarations. smt2 interaction language, within scope of parsesmtlib2file there no interaction, no commands excuted, e.g., imporant example (check-sat) command, not executed.

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

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 ...
