Hi, I'm trying out RhinoETL and I'm having some issues in trying to wrap my
head around how the EventRaisingEnumerator is used.Specifically, I want to
log the numbers of row processed during the operation, and I'm trying to do
so with this code:
public DeleteData(string connectionStringName) : base(connectionStringName)
{
OnRowProcessed += delegate
{
rowsDeleted++;
});
OnFinishedProcessing += op =>
{
Info("Rows deleted: {0}", rowsDeleted);
};
}
where DeleteData inherits from OutputCommandOperation. With the code that's
on the trunk only the OnFinishedProcessingEvent is raised, therefore 0 is
always logged, printing this out:
Committing DeleteData
Committed DeleteData
Rows deleted: 0
I tried by modifying the OutputCommandOperation class by wrapping the rows
in the Execute method in an EventRaisingEnumerator, but doing so I get this:
Rows deleted: x
Committing DeleteData
Committed DeleteData
Rows deleted: x
Ideally, I'd want the Rows deleted message once after the commit message,
but I think this might be tricky, since I guess the processing is already
wrapped in an EventRaisingEnumerable, just not in the point I would like it.
