Detailed Description

Undoable write of one per-edge attribute across a set of edge slots.

Slots are stored flat (mesh::edgeSlot(cell, edgeLocal)) and both sides of the edit hold the WHOLE MeshEdgeBC, not just the changed field: the BC fields are interdependent through type (a stage value is meaningless once the type flips to Wall), so a partial restore would leave the slot in a state the user never saw.

Conveyance dispatches to applyMeshEdgeConveyance rather than applyMeshEdgeBC in BOTH directions, so the engine's interior-edge symmetry invariant (both halves carry the same value) survives undo.

Constructor & Destructor Documentation

◆ MeshSetEdgeAttributeCommand()

MeshSetEdgeAttributeCommand::MeshSetEdgeAttributeCommand	(	SWMM2DMeshLayer *	layer,
		QByteArray	key,
		QVector< int >	edgeSlots,
		QVector< mesh::MeshEdgeBC >	newBCs,
		QVector< mesh::MeshEdgeBC >	oldBCs,
		const QString &	text,
		MapCanvas *	canvas,
		QUndoCommand *	parent = `nullptr`
	)

Parameters

layer	Mesh layer that owns the edges.
key	Attribute key ("conveyance", "bcType", "head", "slope", "flow", "tseries", "curve", "group", or "bc" for a whole boundary-condition write). "conveyance" selects the mirroring write path; every other key writes the slot.
edgeSlots	Flat edge slots (`mesh::edgeSlot(cell, edgeLocal)`).
newBCs	Parallel to `edgeSlots:` post-edit slot value.
oldBCs	Parallel to `edgeSlots:` pre-edit slot value.
