Method OnDatasetConstructed
|
{
|
Description:
|
[*
|
Run this when the dataset with a `LibOpt_Optimization` inside is constructed.
|
|
We advise to use the following snippet in the OnConstructed of the dataset:
|
|
if( isnull( this.Optimization() ) )
|
{
|
this.Optimization( relnew );
|
}
|
this.Optimization().OnDatasetConstructed();
|
*]
|
TextBody:

|
// Migration: Update existing datasets where `LibOpt_Optimization` does not have a `LibOpt_Beacon`.
|
LibOpt_Beacon::Update( this );
|
this.Update();
|
|
traverse( this, Optimizer.Run, run )
|
{
|
run.OnDatasetConstructed();
|
}
|
|
// Reset the `LibOpt_Optimization.NextRunNr`
|
// When a run is deserialized it may get a `RunNr` that is higher or equal to the `NextRunNr`.
|
// While the dataset is running, the correct `NextRunNr` can be obtained from the `AlgorithmStore`, where it's backed up.
|
// After a server restart this value is no longer in the `AlgorithmStore`, hence we need to calculate it again.
|
this.NextRunNr( maxvalue( this.NextRunNr(),
|
max( this, Optimizer.Run, run, true, run.RunNr() ) + 1 ) );
|
|
// If the current dataset is a copy of some other dataset, then we set the MDSKeyParentDataset attribute.
|
// This allows us to return to the parent dataset by using the 'Reload' button in the 'Replannable snapshots' form.
|
if( this.MDSID() <> this.MDSKeyCurrentDataset() )
|
{
|
this.MDSKeyParentDataset( this.MDSKeyCurrentDataset() );
|
}
|
this.MDSKeyCurrentDataset( this.MDSID() );
|
|
// Get the name of the current dataset.
|
// This value is used to set `LibOpt_ControllerRun.DatasetName`, which is an attribute used for visualization purposes.
|
// the guard below is here in order to prevent errors when the dataset is in temporary storage. For these cases
|
// the dataset name is not important.
|
this.DatasetName( guard( MDSEditor::Editor().ObjectInfo( this.MDSID() ).Name(), 'TEMPORARY' ) );
|
|
// Delete all LibOpt_DatasetCopyConditional that were flagged for deletion before this dataset was loaded or copied
|
LibOpt_DatasetCopyConditional::DeleteDatasetCopyConditionalWhenFlagged( this, true );
