Function Documentation

Enqueue()

void WorksheetEvalQueue::Enqueue	(	GroupCell &	cell,
		EvaluationQueue &	queue
	)

Append one group cell to the queue if it is eligible.

Marks the cell's editor as containing (not-yet-evaluated) changes - which greys out its stale output - and then queues the cell. A no-op for cells ShouldEnqueue() rejects.

EnqueueRange()

void WorksheetEvalQueue::EnqueueRange	(	GroupCell *	start,
		const GroupCell *	end,
		EvaluationQueue &	queue
	)

Enqueue every eligible cell in the inclusive range [start, end].

Walks the group-cell list forward from start, calling Enqueue() on each cell, and stops after the cell equal to end. A null end means "to the end of the document".

ShouldEnqueue()

bool WorksheetEvalQueue::ShouldEnqueue

(

const GroupCell &

cell

)

Is this group cell eligible for evaluation?

Only a visible code cell that actually owns an editor can be evaluated; text and sectioning cells, hidden (folded-away) cells and the odd editor-less code cell are skipped.
