Detailed Description

Segment linkage class.

Segment linkage data contains a list with a foreward, and a back pointer for each segment. The "null" pointer is assigned to the backward pointer of the first element and foreward pointer of the last element of each list.

seg_db::seg_index sends::seg_db::linkage::end

(

void

)

const [inline]

Get the end segment index.

Get the end segment index. THis is used as the null pointer.

Returns:

Index of segment before the argument segment.

Referenced by sends::seg_db::qbase::next(), and sends::seg_db::qbase::prev().

void sends::seg_db::linkage::insert_before	(	seg_index	inx,
		seg_index	iaft
	)			[inline]

Insert a segment into the linkage list.

Insert segment 'inx' into the linked list before segment iaft.

Parameters:

	inx	Index of segment to be inserted
	iaft	Segment in list before which the new segment will be inserted.

void sends::seg_db::linkage::insert_after	(	seg_index	inx,
		seg_index	past
	)			[inline]

Insert a segment into the linkage list.

Insert segment 'inx' into the linked list after segment past.

Parameters:

	inx	Index of segment to be inserted
	past	Segment in list after which the new segment will be inserted.

seg_db::seg_index sends::seg_db::linkage::next

(

seg_index

inx

)

const [inline]

Get the next segment index.

Get the index of the segment following the argument segment in the linked list.

Parameters:

inx

Current segment index.

Returns:

Index of segment following the argument segment.

Referenced by sends::seg_db::qbase::next().

bool sends::seg_db::linkage::null

(

seg_index

inx

)

const [inline]

test if index is null (equal to end()).

Test whether the specified index is null.

Parameters:

inx

Index to be tested.

Returns:

True if index is null.

seg_db::seg_index sends::seg_db::linkage::prev

(

seg_index

inx

)

const [inline]

Get the previous segment index.

Get the index of the segment before the argument segment in the linked list.

Parameters:

inx

Current segment index.

Returns:

Index of segment before the argument segment.

Referenced by sends::seg_db::qbase::prev().

void sends::seg_db::linkage::unlink

(

seg_index

inx

)

[inline]

Unlink a segment.

Remove the specified segment from the linked list. The previous and next segments in the list are linked together and both links for the specified segment are replaced by the null link value (end).

Parameters:

inx

Index of the segment to be unlinked.
