Object–Based PeopleCode

 

What is Object – Based PeopleCode:

• Introduced in PeopleTools 8
• Evolution of procedural-based PeopleCode
• Provides for complex object definitions
• Overcomes procedural data scope limitations
• Similar to Visual Basic notation
• Interpreted (like VB)
• Not completely object oriented (like C++), but it’s getting there!
• Does not support polymorphisms
• Does support multiple inheritance
• Backwards compatible

Why do we need Object Based PeopleCode:

• Greater ability to write generic code
• Release 8 Integration
                       1. Component Interface
                       2. Application Messaging
                       3. Business Interlinks
• Ability to define custom classes (Release 8.4)
                       1. Application Classes/Packages
                       2. Replaces FUNCLIB Processing

Advantage of Object and Methods:

• Tight code
• Syntax is validated*
• No or low maintenance required

Object – Based PeopleCode Rule:

• DECLARE the object
• INSTANTIATE the object

Object–Based Code to avoid use of SQLEXEC

 

Below code can be used to avoid use of SQLExec.

SQLExec Code:

SQLExec to copy a row from ORD_HDR to ORD_HDR_EXT.

&ORD_NO = &NEW_ORD_NO;

SQLExec("select %timeout(order_dt), training_loc, vendor_cd, order_status, status_dt, deliver_method from ps_ord_hdr
where order_nbr = :1"
, &ORD_NO, &ORD_DT, &TRAIN_LOC,&VEND_CD, &ORD_STAT, &STAT_DT, &SHIP_VIA);

SQLExec("delete from ps_ord_hdr_ext where order_nbr = :1", &ORD_NO);

SQLExec("insert into ps_ord_hdr_ext (order_nbr, order_dt,training_loc, vendor_cd, order_status, status_dt,
deliver_method) values(:1,%datein(:2),:3,:4,:5,:6,:7)"
,&ORD_NO, &ORD_DT, &TRAIN_LOC, &VEND_CD, &ORD_STAT, &STAT_DT,&SHIP_VIA);

Same logic using Object Based code:

Local Record &REC1, &REC2;
&REC1 = GetRecord(RECORD.ORD_HDR);
&REC2 = CreateRecord(RECORD.ORD_HDR_EXT);
&REC1.ORD_NO = &NEW_ORD_NO;
&REC1.SelectByKey();
&REC1.CopyFieldsTo(&REC2);
&REC2.Delete();
&REC2.Insert();
