Example OCCI Application
Example OCCI Application
This OCCI application example extends the OTT-generated C++ classes and
translates inherited object types. Each class in this application contains a constructor
to initialize class objects and a method to display the values assigned to the
attributes of the object. The MyPerson class also has a method to change the curr_
addr attribute. All the classes here are derived from the generated classes.
Create the needed types and tables for the OCCI application as illustrated in the
following code example:
connect scott/tiger
create type full_name as object (first_name char(20), last_name char(20));
create type address as object (state char(20), zip char(20));
create type address_tab as varray(3) of ref address;
create type person as object (id number, name full_name,
curr_addr ref address, prev_addr_l address_tab) not final;
create type student under person (school_name char(20));
/* tables needed in the user-written occi application */
create table addr_tab of address;
create table person_tab of person;
create table student_tab of student;
The INTYPE file provided to the OTT utility contains the following information:
CASE = SAME
MAPFILE = registerMappings.cpp
TYPE FULL_NAME GENERATE CFullName AS MyFullName
HFILE=cfullname.h
CPPFILE=cfullname.cpp
TRANSLATE first_name as FirstName
last_name as LastName
TYPE ADDRESS GENERATE CAddress AS MyAddress
HFILE=caddress.h
CPPFILE=caddress.cpp
