Detailed Description

Associate a Data Present Bitmap to decoded variables in a subset.

Constructor & Destructor Documentation

wreport::bulletin::Bitmap::Bitmap	(	const Var &	bitmap,
		const Subset &	subset,
		unsigned	anchor
	)

Create a new bitmap.

Parameters

bitmap	The bitmap variable
subset	The subset to which the bitmap refers
anchor	The index to the first element after the end of the bitmap (usually the C operator that defines or uses the bitmap)

std::vector<unsigned>::const_reverse_iterator wreport::bulletin::Bitmap::iter

Iterator over refs.

Since refs is filled while going backwards over the subset, iteration is done via a reverse_iterator.
