一直想写一些关于oo abap编程的东西，但有许多的问题需要跨越，首先就是abap的gui的类的，现在将sap字典用于存储类信息的表列出，供大家参考学习。
一、类的基本定义信息存储的表===============================================Class/Interface===============================================SEOCLASS(CLSNAME(30))Class/Interface(存储类的基本定义)--------------------------------------------------------------------------------------------------------SEOCLASSDF(CLSNAME(30),VERSION(0/1))Definition of class/interface(存储)--------------------------------------------------------------------------------------------------------SEOCLASSTX(CLSNAME(30),LANG)Short description class/interface(存储类描叙)++++++++++++++++++++++++++++++++++++++++++++++++++++SEOFRIENDS(CLSNAME(30),REFCLSNAME(30),FRIENDTYPE(0/1),VERSION(0/1))Friend relationship(存储友元类)--------------------------------------------------------------------------------------------------------SEOMETAREL(CLSNAME(30),REFCLSNAME(30),VERSION(0/1))Inherited Superclass and Interface(继承的父类和实现的接口，区分参见备注)Meta relationship--------------------------------------------------------------------------------------------------------SEOREDEF(CLSNAME(30),REFCLSNAME(30),VERSION(0/1),MTDNAME(61))(存储重新定义父类的方法)Redefined methods for each inheritance relationship--------------------------------------------------------------------------------------------------------SEOTYPEPLSType group application--------------------------------------------------------------------------------------------------------Memo：SEOCLASS～CLSTYPE0->class1->Interface
SEOMETAREL~RELTYPE0->Interface composition (i COMPRISING i_ref)1->Interface implementation (CLASS c. INTERFACES i_ref)2->Inheritance (c INHERITING FROM c_ref)5->Enhancement ( c enhances c_ref)
SEOFRIENDS~FRIENDTYPE0->Global Friend Relationship1->Local Friend Relationship
SEOFRIENDS~VERSION0->Inactive1->Active2->Deleted
二、类的方法和事件的定义存储的表===============================================Class Component===============================================SEOCOMPO(CLSNAME(30),CMPNAME(30),)Class/Interface component--------------------------------------------------------------------------------------------------------SEOCOMPODF(CLSNAME(30),CMPNAME(30),VERSION(0/1),)Definition class/interface component--------------------------------------------------------------------------------------------------------SEOCOMPOTX(CLSNAME(30),CMPNAME(30),LANG,)Short description class/interface component--------------------------------------------------------------------------------------------------------Memo：SEOCOMPO～CMPTYPE1->Attribute2->Method3->Event4->Type
SEOCOMPO～MTDTYPE0->Method1->Event handling method2->Constructor3->Destructor4->Get-method of a virtual attribute5->Set-method of a virtual attribute6->Factory Method of a Business Class
SEOCOMPODF~EXPOSURE0->Private1->Protected2->Public--------------------------------------------------------------------------------------------------------
三、类的事件和方法的参数和异常定义存储的表===============================================Class Component's subcomponent===============================================SEOSUBCO(CLSNAME(30),CMPNAME(30),SCONAME(30))--------------------------------------------------------------------------------------------------------SEOSUBCODF(CLSNAME(30),CMPNAME(30),SCONAME(30),VERSION(0/1))--------------------------------------------------------------------------------------------------------SEOSUBCOTX(CLSNAME(30),CMPNAME(30),SCONAME(30),LANG)--------------------------------------------------------------------------------------------------------Memo：SEOSUBCO~SCOTYPE0->Parameters1->Exception-----------------------------------------------------------------------------------------------------
四、读取类信息的相关函数===============================================Relation Function ===============================================SEO_CLASS_EXISTENCE_CHECKSEO_CLASS_TYPEINFO_GETSEO_ATTRIBUTE_READ_ALLSEO_METHOD_READ_ALLSEO_EVENT_READ_ALLSEO_PARAMETER_READ_ALLSEO_TYPE_READ_ALLSEO_INHERITANC_READSEO_IMPLEMENTG_READ_ALLSEO_FRIENDSHIP_READ_ALLSEO_TYPEPUSAGE_READ_ALLSEO_CLSDEFERRD_READ_ALLSEO_INTDEFERRD_READ_ALLSEO_CLASS_RESOLVE_INHERITANCESEO_CLASS_RESOLVE_IMPLEMENTGS
