Constructor & Destructor Documentation

KateBuffer::KateBuffer ( KTextEditor::DocumentPrivate *  doc )

explicit

Create an empty buffer.

Parameters

doc	parent document

(with one block with one empty line)

Definition at line 36 of file katebuffer.cpp.

KateBuffer::~KateBuffer ( )

override

Goodbye buffer.

Cleanup on destruction.

Definition at line 52 of file katebuffer.cpp.

Member Function Documentation

bool KateBuffer::brokenEncoding ( ) const

inline

Did encoding errors occur on load?

Returns

encoding errors occurred on load?

Definition at line 118 of file katebuffer.h.

bool KateBuffer::canEncode

(

)

Can the current codec handle all chars.

Returns

chars can be encoded

Definition at line 190 of file katebuffer.cpp.

void KateBuffer::clear ( )

overridevirtual

Clear the buffer.

Reimplemented from Kate::TextBuffer.

Definition at line 109 of file katebuffer.cpp.

KTextEditor::Range KateBuffer::computeFoldingRangeForStartLine

(

int

startLine

)

For a given line, compute the folding range that starts there to be used to fold e.g.

from the icon border

Parameters

startLine

start line

Returns

folding range starting at the given line or invalid range when there is no folding start or startLine is not valid

Definition at line 416 of file katebuffer.cpp.

int KateBuffer::count ( ) const

inline

Return the total number of lines in the buffer.

Definition at line 179 of file katebuffer.h.

bool KateBuffer::editChanged ( ) const

inline

were there changes in the current running editing session?

Returns

changes done?

Definition at line 68 of file katebuffer.h.

void KateBuffer::editEnd

(

)

finish some editing action

Definition at line 63 of file katebuffer.cpp.

void KateBuffer::editStart

(

)

start some editing action

Definition at line 56 of file katebuffer.cpp.

int KateBuffer::editTagEnd ( ) const

inline

dirty lines end

Returns

end line

Definition at line 86 of file katebuffer.h.

bool KateBuffer::editTagFrom ( ) const

inline

line inserted/removed?

Returns

line inserted/removed?

Definition at line 95 of file katebuffer.h.

int KateBuffer::editTagStart ( ) const

inline

dirty lines start

Returns

start line

Definition at line 77 of file katebuffer.h.

void KateBuffer::ensureHighlighted	(	int	line,
		int	lookAhead = 64
	)

Update highlighting of given line line, if needed.

If line is already highlighted, this function does nothing. If line is not highlighted, all lines up to line + lookAhead are highlighted.

Parameters

lookAhead

also highlight these following lines

Definition at line 242 of file katebuffer.cpp.

void KateBuffer::invalidateHighlighting

(

)

Invalidate highlighting of whole buffer.

Definition at line 321 of file katebuffer.cpp.

bool KateBuffer::openFile	(	const QString &	m_file,
		bool	enforceTextCodec
	)

Open a file, use the given filename.

Parameters

m_file	filename to open
enforceTextCodec	enforce to use only the set text codec

Returns

success

Definition at line 123 of file katebuffer.cpp.

Kate::TextLine KateBuffer::plainLine ( int  lineno )

inline

Return line lineno.

Highlighting of returned line might be out-dated, which may be sufficient for pure text manipulation functions, like search/replace. If you require highlighting to be up to date, call ensureHighlighted prior to this method.

Definition at line 158 of file katebuffer.h.

bool KateBuffer::saveFile

(

const QString &

m_file

)

Save the buffer to a file, use the given filename + codec + end of line chars (internal use of qtextstream)

Parameters

m_file

filename to save to

Returns

success

Definition at line 212 of file katebuffer.cpp.

void KateBuffer::setHighlight

(

int

hlMode

)

Use highlight for highlighting.

highlight may be 0 in which case highlighting will be disabled.

Definition at line 292 of file katebuffer.cpp.

void KateBuffer::tagLines ( KTextEditor::LineRange  lineRange )

signal

Emitted when the highlighting of a certain range has changed.

bool KateBuffer::tooLongLinesWrapped ( ) const

inline

Too long lines wrapped on load?

Returns

too long lines wrapped on load?

Definition at line 127 of file katebuffer.h.

void KateBuffer::unwrapLine ( int  line )

overridevirtual

Unwrap given line.

Parameters

line	line to unwrap

Reimplemented from Kate::TextBuffer.

Definition at line 271 of file katebuffer.cpp.

void KateBuffer::updateHighlighting

(

)

Update highlighting of the lines in last edit transaction.

Definition at line 83 of file katebuffer.cpp.

void KateBuffer::wrapLine ( const KTextEditor::Cursor &  position )

overridevirtual

Wrap line at given cursor position.

Parameters

position

line/column as cursor where to wrap

Reimplemented from Kate::TextBuffer.

Definition at line 261 of file katebuffer.cpp.
