public abstract class AbstractORContainer extends AbstractContainerBean implements ISQLWrapper, IPersistence
Abstract Object-Relational Container - USed for representation KSDS Indexed files. COBOL Structures for accessing Indexed-File are be translated to an Object-Relational (OR) design which read/write from a SQL Database instead of file system.
Such classes inherit from SQLWrapper or AbstractORContainer. The major part functionality for CRUD operations are provided in these classes.
The SQLWrapper class does the same thing, but when REDEFINES, OCCURS-DEPENDING, ... and generally COBOL emulation is not required, then this version can give a much better performance.

    • isChangeGEConditonToLIKE

      public boolean isChangeGEConditonToLIKE()
      Description copied from interface: ISQLWrapper
      The system can replace GE searches to LIKE statements. this can potentially have a huge performance improvement.
      E.g. Consider generating SELECT ... from TABLE WHERE KEY_1 >= ? AND KEY_2 >= ?.
      If each key is 5 chars, and the supplied values are "A " and "B " - the above translates to: 
       SELECT ... from TABLE WHERE KEY_1 >= 'A    ' AND KEY_2 >= 'B    '.

      Converting it to LIKE will become 
       SELECT ... from TABLE WHERE KEY_1 LIKE 'A%' AND KEY_2 LIKE 'B%'
      This makes a significant performance improvements.

    • assignTableName

      public void assignTableName(String newName)
      Called Programs declaring instances of the persistence classes
      FOr Indexed-Files, this call often relates to setting name to a data-file name E.g. for
      SELECT CUSTOMER-FILE assign to "CUSTOMER.DAT"
      Results in:
      customerFile.assignTableName("customer.dat");
      or
      customerFile.assignTableName(System.getEnv("CUST");
      this is incorrect. We cannot keep changing the table names.

      But we cannot suppress its generation - as the system should be able to swap between IndexedFiles and SQLWrappe/OR . IndexedFiles WILL need this.
      However, the real name can be set by the persistence class itself - using "assignSQLTableName" Besides, this may "sometimes" be useful. So, the system is going to continue generating the call to this method.
