MgLongTransactionReader Class Reference
[MgLongTransactionReader]

Inherits MgSerializable.

List of all members.

Detailed Description

Provides forward-only, read-only functionality for describing a set of long transactions that exist in the feature source.

Remarks:
You must call ReadNext before you can access any data. Calling ReadNext() gives you access to the information about one long transaction. See the example code. MgFeatureService::GetLongTransactions returns an MgLongTransactionReader object.
Example (PHP)
The code in this example has not been tested. It's a start. 
 <?php
 function printLongTransactionReader($longTransactionReader)
 {
    global $logFileHandle;
    $i = 0;
    fwrite($logFileHandle, "Printing long transaction readern");
    while ($longTransactionReader->ReadNext())
    {
       $i++;
       $name = $longTransactionReader->GetName();
       fwrite($logFileHandle, "Name: $namen");
       $desc = $longTransactionReader->GetDescription();
       fwrite($logFileHandle, "Description: $descn");
       $owner = $longTransactionReader->GetOwner();
       fwrite($logFileHandle, "Owner: $ownern");
       $dateTime = $longTransactionReader->GetCreationDate();
       $printableDateTime = printDateTime($dateTime);
       fwrite($logFileHandle, "Creation Date: $printableDateTimen");
       $isActive = $longTransactionReader->IsActive();
       $printableIsActive = prtBool($isActive);
       fwrite($logFileHandle, "IsActive: $printableIsActiven");
       $isFrozen = $longTransactionReader->IsFrozen();
       $printableIsFrozen = prtBool($isFrozen);
       fwrite($logFileHandle, "IsFrozen: $printableIsFrozenn");
       $parentLongTransactionReader = $longTransactionReader->GetParents();
       if ($parentLongTransactionReader == NULL)
       {
          fwrite($logFileHandle, "There is no parent long transactionn");
       }
       else
       {
          fwrite($logFileHandle, "Printing parent long transaction readern");
          printLongTransactionReader($parentLongTransactionReader);
          $parentLongTransactionReader->Close();
       }
       $childrenLongTransactionReader = $longTransactionReader->GetChildren();
       if ($childrenLongTransactionReader == NULL)
       {
          fwrite($logFileHandle, "There are no child long transactionsn");
       }
       else
       {
          fwrite($logFileHandle, "Printing children long transaction readern");
          printLongTransactionReader($childrenLongTransactionReader);
          $childrenLongTransactionReader->Close();
       }
    }
    fwrite($logFileHandle, "Printed $i long transaction(s)n");
 }
