Method Detail

canEdit

public static boolean canEdit(ViTextView tv,
                              ViBuffer buf,
                              int offset)

beginlineColumnIndex

public static final int beginlineColumnIndex(int flags,
                                             TextUtil.MySegment txt)

Move cursor to start of line.

• if flags & BL_WHITE move to first non-white
• if flags & BL_SOL move to first non-white if startofline is set, otherwise keep "curswant" column
• if flags & BL_FIX don't leave the cursor on a NUL.

NEEDSWORK:

• This belongs as part of the document since the Content and hence the segment can not be accessed publicly, only protected.

beginline

public static final void beginline(int flags)

NEEDSWORK:

• This often follows an operation that get the segment, and here we are getting it again in BEGIN_LINE.

oneright

public static int oneright()

oneright oneleft cursor_down cursor_up Move one char {right,left,down,up}. Return OK when successful, FAIL when we hit a line of file boundary.

oneleft

public static int oneleft()

cursor_up

public static int cursor_up(int n,
                            boolean upd_topline)

When TRUE: update topline.

cursor_down

public static int cursor_down(int n,
                              boolean upd_topline)

Parameters:

n - the number of lines to move

upd_topline - When TRUE: update topline.
