CATIACAA应用开发的过程与方法

应用开发的过程与方法

命名方法详见《应用开发中的命名规则》

一、系统安装与环境配置

1.1系统安装

1.1.1VC＋＋

1.1.2CATIA

1.1.3组建应用接口（CAA）

1.1.4快速应用开发环境（RADE）

1.2应用开发环境配置

二、目录结构的建立

2.1创建工作空间（Workspace）

InMicrosoftDeveloperStudioopenmenu"File"andselect"OpenCAAV5Workspace",thefollowingwindowappearsinwhichyoucanselecttoopenyourworkspacewiththe"mkmk"functionalities.

EithermodewillgiveyouaccesstotheCodeGeneratorfeatures.

Onceyouhavefilledintheworkspaceinformation,clickon"OK".Alogwindowappearswhileyourenvironmentisupdatedandtheworkspaceopened.WhenthiswindowhasdisappearedDeveloperStudioloadstheprojectfilesitstoredinyourworkspaceandyouarereadytowork.

ThecommandsavailableintheCodeGeneratorareasetofwizardswhereinyouspecifyaseriesofparametersanditwillgeneratecodeforyou.Beforecreatingthecode,areportwindowappearssothatyoumayverifythatthecodegeneratedisasyouexpectit.

Youmayfindthatsomeofthegeneratedsourcefilescontaincommentedoutstatementssuchas"DONOTEDIT:

2.2定义组件框架（CAAV5Framework/ImplementationFramework）

InMicrosoftDeveloperStudio,openmenu"Project"andselect"NewFramework…"

Thewizardwillthencreatethefollowingdirectorystructure:

Educationtypeframeworksaresuffixed".edu"andTestframeworksaresuffixed".tst".Thewizardappendsthesesuffixestothenameoftheframework.

2.3定义接口空间（InterfaceFramework）

Aninterfaceframeworkisaframeworkthatcontains（mainly）interfacesinbothC++orIDLlanguage.Thestructureofthisinterfaceisveryspecific.V5namingconventionsrequiresthattheseinterfacesbedistinguishablethroughan"Interfaces"suffix.Thereforeifyoutypein"Bird"intheframeworkname,thegeneratedframeworkwillbecalled"BirdInterfaces".Thegeneratedstructureisthefollowing:

Afterthefilestructurehasbeencreated,theC++InteractiveDashboardupdatesyourDeveloperStudioprojecttotakeintoaccountthenewfilesanddirectories.IntheJavaInteractiveDashboard,youwillseethenewframeworkintheworkspacetreeview.Notethattheframeworkissetasthecurrentlyactiveproject.

2.4定义模块（Module）

InMicrosoftDeveloperStudio,openmenu"Project"andselect"NewModule…"

Whenyouclickon"OK"areportwindowisdisplayedtoshowyouthefilesanddirectoriesthatwillbecreated.Ifyouaccept,thefollowingfilestructurewillbecreated:

三、类定义

CodeGeneratorwizardsenableyoutocreatespecificV5objectsthatimplementcustomaryV5patterns.Thesecurrentlyinclude:

∙Objectmodelerinterfaces（bothC++andIDL）

∙Objectmodelerimplementations

∙V5documents

∙V5features.

InMicrosoftDeveloperStudio,sourcecodeisgeneratedinthecurrentlyactivemodule.Iftheactiveprojectisnotamodule,thefollowingwarningboxwillaskyoutoselectanactivemodule.InMicrosoftDeveloperStudio,thisisdonebyactivatingthecontextualmenuonthedesiredMicrosoftproject（"Setasactiveproject"）. 

WhenyougeneratesourcecodeusingtheCodeGenerator,yourworkspaceisupdatedtotakeintoaccountthefilesnewlycreated.InDeveloperStudioonly,thisoftenresultsinthefollowingwarning:
