Take a full span and test if it would have changed this c-buffer line on insertion
~csCBufferLine ()
Destruct a c-buffer line and free all used spans

Documentation

A line in the CBuffer. Spans are allocated on an as-needed base. But they are not freed. Instead, unused spans are put in the first_unused list (in csCBuffer). The size of this list will always be equal to the maximum number of spans once used on screen.
csCBufferSpan* first_span
List of all empty spans on this line.

csCBufferSpan* last_span
Pointer to last span in the list of empty spans.

csCBuffer* parent
Parent C-buffer.

csCBufferLine()
Initialize a c-buffer line.

~csCBufferLine()
Destruct a c-buffer line and free all used spans. Note: the spans are really freed and not put in the unused list.

void SetParent(csCBuffer* par)
Set parent.

void Initialize(int startx, int endx)
Initialize this line to the given empty span

bool IsFull()
Return true if this line if full (i.e. no empty spans left).

void MakeFull()
Make this line full.

bool TestSpan(int startx, int endx)
Take a full span and test if it would have changed this c-buffer line on insertion. This means that the span is visible.

bool InsertSpan(int startx, int endx)
Take a full span and insert it into the c-buffer line. Return true if the span line was modified (i.e. the span is visible).

bool TestSingle(int x)
Test if a given one-element-scan is full or empty (i.e. return true if visible).

void Dump()
Dump information about this scanline.
