(PAS for OE only)
Creates and modifies an application server's export list, which specifies the remote procedures that a client application can execute in the current application server session.
Return type: LOGICAL
Applies to: SESSION system handle
The EXPORT( ) method applies only to application servers. That is, if the REMOTE attribute of the SESSION handle is FALSE, EXPORT( ) does nothing and returns FALSE.
The EXPORT( ) method can be called repeatedly within the context of the application server instance. Each time EXPORT( ) is called, the application server instance adds the procedures in list to its export list. If you do not specify list, the EXPORT( ) method resets the export list to empty.
The EXPORT( ) method performs pattern matching by comparing two procedure names character-by-character, taking wildcards into account. Procedure names must match exactly. Case (uppercase and lowercase) is significant.
If the EXPORT( ) method is never called, a client application can call any procedure in the application server's PROPATH. Once EXPORT( ) is called in the context of an application server, a client application can call only the procedures in the export list.
Typically, the Connect procedure or Startup procedure of an application server calls the EXPORT( ) method, depending on the operating mode. For example, where you might call it from the Connect procedure on a session-managed application server, you would probably call it from the Startup procedure on a session-free application server. For more information on Connect procedures, see the reference entry for the CONNECT( ) method (Progress Application Server for OpenEdge).
