Description |
|---|---|
|
methodname |
Name of the method that throws an exception. |
|
arguments |
Arguments of the method that throws an exception. Depending on the method, the method arguments can be optional. |
|
ExceptionType |
Object of type Throwable. Usually the object type thrown is a user-defined exception class derived from the system Exception class. If you define multiple potential exceptions for a method, you can throw each type of exception in the same clause by separating the exception types with commas. |
Usage
Internal use only.
You do not type or otherwise add the THROWS clause to function calls in a PowerBuilder script. However, you can add a THROWS clause to any PowerBuilder function or to any user event that is not defined by a pbm event ID.
For more information about adding a THROWS clause to a function or event prototype, see the section called “Defining a THROWS clause” in Users Guide. For more information about exception handling, see the section called “Exception handling in PowerBuilder” in Application Techniques.
