sendDirectTransaction

public void sendDirectTransaction(Transaction trans)

Send a transaction directly to be processed.

Specified by:

sendDirectTransaction in interface ClientSessionManagerInterface

Parameters:

trans - The transaction to process immediately.

processInboundTransaction

protected boolean processInboundTransaction(int transCode,
                                Transaction trans)

Processes a transaction.

Parameters:

transCode - The transaction code.

trans - The transaction.

Returns:

true if the transaction is processed somehow, even if "sent directly" to the AWT thread.

processInboundTransactionWithDragLock

protected boolean processInboundTransactionWithDragLock(int transCode,
                                            Transaction trans)

Processes a transaction.

Parameters:

transCode - The transaction code.

trans - The transaction.

Returns:

true if the transaction is processed somehow, even if "sent directly" to the AWT thread.

callObject

public String callObject(String objectID,
                String argID,
                int action,
                String argString,
                boolean doModal)
                  throws InterruptedException

Calls an object in the server. For values of the "action" parameter, see the documentation of se.entra.phantom.server.ObjectMessages and the constants OBJACT_*.

The parameter "doModal" can be set to "true" in which case the caller thread is blocked until the object has completed execution in the server (regardless if it is a REXX Macro or REXX Application).

Note that it can be "dangerous" to run modally in e.g. the AWT event thread (painting in windows and components will be blocked), and that if a message box displayed on the client side (due to the REXX function message), it must be removed by the user prior to the blocking to be released.

The "doModal" flag can NOT be set to "true" when processing updates to panels or components from the server, nor when responding to server-induced transactions, because these functions blocks the Client Socket reader thread that is used to receive the modal reply. If "doModal" is "true" and the Socket reader thread is blocked, an "InternalError" exception is thrown.

This method is thread-safe when running modally, so if possible, start a new thread to handle modal replies.

Returns:

null if the object is not found in the server or the action parameter is invalid, otherwise the return string from the object. When "doModal" is "false", null is always returned.

Throws:

InterruptedException - Only when "doModal" is "true" and the blocked thread was interrupted.

InternalError - If the calling thread requests a modal callObject and is currently executing transactions from the Socket reader thread or the AWT event dispatch thread.
