Base class to implement managed tasks
Syntax
LOADLIB "mod::system/lib/tasks.whlib";
OBJECTTYPE ManagedTaskBase
Variables
- BOOLEAN debug
Whether debugging is enabled for this task
- STRING mutex
If set, mutex to lock in the work that is opened around ExecuteTask
Functions
- RECORD FUNCTION GetTaskMetadata()
Returns the task metadata
- MACRO PrepareTask(RECORD data)
Override PrepareTask with your task preparation code code. This function is called without work, and can be used to do long I/O. Result data can be stored in the current object. Throw exceptions if something fails and you want to be restarted. No database work is opened when this function runs
- MACRO RunTask(RECORD data)
Override RunTask with your task code. This function is run with open work, so keep I/O to a minimum (use PrepareTask instead). Throw exceptions if something fails and you want to be restarted, and use ResolveByRestart for a graceful continuation later
