1 New Features for Object Oriented Development with the A ystem Rob Owen A Institute

2 Agenda Classes Features Utilities OLE enhancements Remote Objects

3 Classes Control Class DataForm Class Graphics Class Map Class Tab Layout Class

4 Control Class ize control smaller than region simpler to make good looking combo boxes _ET_IZE_ method Call end(contrid, _ET_IZE_, <width>, <height>, <units>);

5 DataForm Class Production! Page ear mark indicator methods to control attributes Control DnD look and feel

6 Graphics Class Prism, Cylinder and Hexagon Order bars by response values Overlay bar and line charts Unix printing enhancements pecifying column widths Chart scrolling

7 Tabbed Dialogs Tabbed folders metaphor Divide & organise information into subject areas Also supports groups of tabs Tab Layout Class sashelp.fsp.tabber.class

8 Tabbed Dialogs tabs active tab client area object in client area outline

9 Tabbed Dialogs At the moment: no object attributes create all objects at runtime In the future: object attribute screen define dialog pages at build time can still control dynamically

10 Tabbed Dialogs events generated TAB ELECTED TAB DEELECTED GROUP ELECTED GROUP DEELECTED methods for selection/deslection _GET_ACTIVE_TAB GET_PREV_ACTIVE_TAB GET_ACTIVE_GROUP GET_PREV_ACTIVE_GROUP_

11 Map Class Interactive map features CHORO and BUBBLE types everal marker options Can be placed interactively

12 Map Class Modes of operation add delete rotate select A/EI version being written

13 New Features FRAME variables Catalog concatenation Tool tips

14 Accessing FRAME vars Getting/etting CL variables from method code. Call end( frameid, '_ET_NUM_VAR_', var-name, numeric-value ); Call end( frameid, '_ET_CHAR_VAR_', var-name, character-value ); Call end( frameid, '_GET_NUM_VAR_', var-name, numeric-value ); Call end( frameid, '_GET_CHAR_VAR_', var-name, character-value ); var-name Name of CL variable that you're querying. The name can be an array item. type-value Value to set or return (either character or numeric)

15 Catalog Concatenation Logical combination of catalogs CATNAME CL function CATNAME option of AF command rc = CATNAME(lib.cat, ET, lib1.cat1, lib2.cat2,...); AF c=... CATNAME=lib.cat (lib1.cat1, lib2.cat2,...) lib.cat.first.frame searches lib1.cat1, lib2.cat2,...

16 Catalog Concatenation rc = CATNAME (cat-name, action <, catalog-list <,listid>>); action ET, CLEAR or LIT catalog-list list of catalogs separated by blanks listid a list of catalogs to be concatenated (only valid if catalog=list is blank)

17 Tool Tips Available Works in BUILD mode too Toolbars Descr\nTip for description in attr Graphics Widgets Descr\nTips in region attributes Button appearance

18 Utilities PMENU builder Class Browser CL Analysers Viewtable

19 Menu Builder Interactive way to build: action bars pull down menus dialog boxes Edit saved menus Include or link to existing menus Test

20 Class Browser View hierarchical relationships between classes subclass existing classes edit existing classes copy existing classes print information delete classes

21 Class Browser classbrowser library catalog resource frame

22 CL Analysers CL List Analyser CL Dynamic Performance Analyser CL Coverage Analyser CL tatic Analyser

23 CL List Analyser Frame based list tracing tool pinpoints lists created but not deleted sclprof list trace sclprof list notrace sclprof list notrace batch sclprof list data=dsname

24 Performance Analyser Analyses dynamic performance timing statistics and frequency CL entry, label, function call Identifying bottlenecks Explore alternative algorithms Compare with previously stored

25 Performance Analyser sclprof timer on sclprof timer off af c= sclprof=yes system layout window entry comparison method comparison function call comparison

26 CL Coverage Analyser CL source line coverage unit testing sclprof coverage on sclprof coverage off system integration testing af c= sclprof=coverage

27 CL tatic Analyser Provide system documentation Aid in the maintenance process This tool has two parts: 1.The data collection phase 2.The data presentation phase

28 CL tatic Analyser Collects: ystem flow chart and each individual program flow chart. Entry complexity based on the number of the lines, number of the instructions and number of the basic blocks being generated. Data definitions and reference table include CL entries, methods, functions, variables, widgets(controls), dataset I/O, file I/O, A I/O, submit, A options, A macros, CL list, etc.

29 CL tatic Analyser Data collection phase proc build batch; crossref project=(lib1.cat1 lib1.cat2...) outlib=libname; run; Viewing phase sclprof static lib=your_lib

30 Viewtable Experimental with 6.11 Production with 6.12 Enhancements planned for 6.14 A/FP software is not required unless you want to: edit a table in either table or form view. sort the table.

31 Viewtable Edit/view A datasets Table or Form viewing modes Control colour and fonts of columns ort the data Remove/add cols from display Load an existing.dataform entry Create a data set from scratch... and more.

32 OLE Automation Can now automate embedded and linked objects. _GET_PROPERTY ET_PROPERTY COMPUTE DO_

33 A OLE Automation A is an OLE Automation erver not an OLE server A can be controlled by other scripting environments eg. Visual Basic OleA = CreateObject( A.Application ) OleA = GetObject(, A.Application )

34 A OLE Automation Methods Command(cmdstr) QueryWindow(wname) Quit ubmit(submitstr) Top

35 A OLE Automation Properties Busy CommandWindow CommandWindowVisible RC Resulttring Title Visible Wait

36 A OLE Automation Visual C++ application AOACT Automation Controller Visual Basic application Automation Controller Automation Controller A session

37 A OLE Automation A provides an automation controller in AOACT.EXE AOACT action= datatype= filename= options= sasoact action=browse datatype=data filename=sasuser.prodsale ==> A session with fsview of sasuser.prodsale

38 A OLE Automation sasoact A session sashelp.dispatch scl actions.frame sashelp.actions sasoact action=browse datatype=data filename=c:\courses\clsdata.sd2

39 Remote Objects Built on top of distributed application messaging architecture Currently, done using a dynamic remoting object In the future, syntactically transparent, with standard proxy mechanisms

40 Remote Objects Experi-mental!!! Allows Creating remote objects... between 2 bound A sessions provided by a monitor performs class load instantiation method dispatch return functions

41 Remote Objects Remote A ession Local A ession create remote instance invoke method destroy remote instance CL

42 Remote Objects Methods _Create_Remote_Instance_(rstr,cstr,rc) _Begin_Method_(mstr, rc) _Add_Method_Arg_C_(cval, cmode, rc, cname) _Add_Method_Arg_N_(nval, cmode, rc, cname) _Add_Method_Arg_L_(lval, cmode, rc, cname) _Invoke_Method_(rlist, rc) _Destroy_Remote_Instance_(rc)

43 Remote Objects Remote A ession Local A ession Catalog Object Viewer CL List Model

44 Remote objects Remote A ession Local A ession CL List Model Viewer Not yet!!!!!!

45 Interested??? Please talk to us

46 Conclusion Major new facilities 6.11 ome more useful features Even better application development system

47 Thank DtaPaper you Title for your attention The A ystem for successful decision making
