C# 클래스 _3PA.Lib.DocumentLines

For every scintilla message that involves a position, the exepect position (expected by scintilla) is the BYTE position, not the CHAR position (as anyone would assume at first!) This class enables you to easily get the correspondance between a BYTE position and a CHAR position, it keeps tracks of inserted/deleted lines and register each line's start position, this information allows us to quickly convert BYTE to CHAR position and vice-versa

ByteToCharPosition ( int pos ) : int	Converts a BYTE position to a CHAR position.
CharPositionFromLine ( int index ) : int	Returns the CHAR position where the line begins, this is THE method of this class (since it is the only info we keep on the lines!)
CharToBytePosition ( int pos ) : int	Converts a CHAR position to a BYTE position
DocumentLines ( ) : System	Initializes a new instance
LineCharLength ( int index ) : int	Returns the number of CHAR in a line.
LineFromCharPosition ( int pos ) : int	Returns the line index containing the CHAR position.

FillTheHole ( ) : void	Fixes the hole we created in a line by correcting the start char position or all the following lines (by the amount of _holeLenght) and then rests the _holeLenght
GetCharCount ( IntPtr text, int length, Encoding encoding ) : int	Gets the number of CHAR in a BYTE range
GetCharCount ( int pos, int length ) : int	Gets the number of CHAR int a BYTE range
OnDeletedText ( SCNotification scn ) : void	updates the line info when deleting text
OnInsertedText ( SCNotification scn ) : void	Updates the line info when inserting text
PrivateCharPositionFromLine ( int index ) : int	Returns the CHAR position where the line begins, this is THE method of this class (since it is the only info we keep on the lines!)
Reset ( ) : void	Simulates the insertion of the whole text, use this to reset the lines info (when switching document for instance)
SciGetLength ( ) : int	Returns the document lenght in BYTES
SciGetLineCount ( ) : int	returns the number of lines in the document
SciLineFromPosition ( int pos ) : int	returns the line that contains the BYTE position pos in the document
SciLineLength ( int line ) : int	returns the length (nb of BYTE) of the line, including any line end CHARs
SciPositionFromLine ( int line ) : int	returns the document BYTE position that corresponds with the start of the line
SciPositionRelative ( int position, int nb ) : int	Count a number of whole characters before or after the argument position and return that position The minimum position returned is 0 and the maximum is the last position in the document
SetHoleInLine ( int line, int charLength ) : void	Creates a hole in a given line (charLength is added to the existing _holeLenght)
