Setting Operation Arguments

The operation you retrieve using ostc_Session::getOperation() contains default value arguments; that is, every argument is set to 0. To set arguments to nondefault values, use ostc_Operation::setArgument():

Example

      transfer->setArgument("from_acct_name", from_name);
      transfer->setArgument("to_acct_name", to_name);
      transfer->setArgument("amount", amount);

"from_acct_name", "to_acct_name", and "amount" are the names of the arguments being set.

from_name, to_name, and amount are the values to which the arguments are being set.

Argument Value Types

The value of an argument must be one of the following types:

• Integer type
  
• float
  
• double
  
• char*
  
• ostc_OID* (object identifier set by user)
  
• void* (for bit vectors)
  

These are the fundamental types used to pass data between thin client and Component Server. There is an overloading of set_argument() for each of these types.

Getting Arguments

You can also use members of ostc_Operation to retrieve an operation's formal and actual arguments.
