Detailed Description

Undoable deletion of a node, link, rain gage, or subcatchment.

The constructor snapshots the object's full property state (before redo() deletes it). undo() re-creates the object and restores all properties. For node deletion, cascade-deleted links are also re-created on undo.

◆ DeleteObjectCommand()

DeleteObjectCommand::DeleteObjectCommand	(	SWMMModelLayer *	layer,
		const QString &	name,
		TargetKind	kind,
		MapCanvas *	canvas,
		QUndoCommand *	parent = `nullptr`
	)

Constructor for node deletion. Snapshots the node + identifies cascade links.

Here is the call graph for this function:

◆ setEngineAppliedByBatch()

void DeleteObjectCommand::setEngineAppliedByBatch ( bool b )

inline

Batch mode (perf-plan Phase A2): the owning BatchDeleteCommand's one swmm_*_delete_many call performs the deletion, so this child keeps only its snapshot + undo role and redo() becomes a no-op.

◆ undo()

void DeleteObjectCommand::undo ( )
