generics - How to use exporting parameter with type ANY -


i have incoming deep structure in recursive method contains structures , tables, i'm working rtti check type, loop on , operation, in case found specific component.

if current component structure or table, method calls itself.

problem: import structure type any. far good. , want export type also.

and here struggle.

how can assign edited deep structure export parameter ?

method process_input.  data: lo_type_descr   type ref cl_abap_typedescr,       lo_struct_descr type ref cl_abap_structdescr,       lv_comp_found   type abap_bool.  field-symbols: <fs_table>     type table,                <fs_value>     type any.  lo_type_descr ?= cl_abap_typedescr=>describe_by_data( p_data =  im_input  ).  if lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct2 or    lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct1.   lo_struct_descr ?= cl_abap_structdescr=>describe_by_data( p_data =  im_input  ).   loop @ lo_struct_descr->components assigning field-symbol(<fs_comp>).     assign component sy-tabix of structure  im_input  <fs_value>.     lo_type_descr ?= cl_abap_typedescr=>describe_by_data( p_data = <fs_value> ).     lv_comp_found = abap_false.      if  lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct2 or         lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct1  or         lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_table.       process_input(         exporting           im_input    = <fs_value>           im_list = im_list       ).     else.       read table im_list data(element) key service_part = <fs_comp>-name binary search.       if sy-subrc eq 0.         <fs_value> = 'test :)'.       endif.     endif.   endloop. elseif lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_table.   assign  im_input <fs_table>.   loop @ <fs_table> assigning field-symbol(<fs_tab_index>).     lo_struct_descr ?= cl_abap_structdescr=>describe_by_data( p_data = <fs_tab_index> ).     loop @ lo_struct_descr->components assigning <fs_comp>.       assign component sy-tabix of structure <fs_tab_index> <fs_value>.       lo_type_descr ?= cl_abap_typedescr=>describe_by_data( p_data = <fs_value> ).       lv_comp_found = abap_false.        if  lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct2 or           lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_struct1  or           lo_type_descr->type_kind eq cl_abap_typedescr=>typekind_table.          process_input(           exporting             im_input = <fs_value>             im_list  = im_list         ).       else.         read table im_list element key service_part = <fs_comp>-name binary search.         if sy-subrc eq 0.           <fs_value> = 'test :)'.         endif.       endif.     endloop.   endloop. endif. reference of im_input lv_cont. ex_input = im_input. endmethod.

generic export parameters working beautifully:

class lcl definition.  public section.   methods: process_input importing im_input type                          exporting ex_input type any. endclass.

so problem lies elsewhere.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
