Constructor & Destructor Documentation

◆ KateBuffer()

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

explicit

Create an empty buffer.

Parameters

doc	parent document

(with one block with one empty line)

Definition at line 35 of file katebuffer.cpp.

◆ ~KateBuffer()

KateBuffer::~KateBuffer ( )

overridedefault

Goodbye buffer.

Cleanup on destruction.

Member Function Documentation

◆ brokenEncoding()

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.

◆ canEncode()

bool KateBuffer::canEncode ( )

Can the current codec handle all chars.

Returns: chars can be encoded

Definition at line 180 of file katebuffer.cpp.

◆ clear()

void KateBuffer::clear ( )

overridevirtual

Clear the buffer.

Reimplemented from Kate::TextBuffer.

Definition at line 97 of file katebuffer.cpp.

◆ computeFoldingRangeForStartLine()

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 438 of file katebuffer.cpp.

◆ count()

int KateBuffer::count ( ) const

inline

Return the total number of lines in the buffer.

Definition at line 188 of file katebuffer.h.

◆ editChanged()

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.

◆ editEnd()

void KateBuffer::editEnd ( )

finish some editing action

Definition at line 60 of file katebuffer.cpp.

◆ editStart()

void KateBuffer::editStart ( )

start some editing action

Definition at line 53 of file katebuffer.cpp.

◆ editTagEnd()

int KateBuffer::editTagEnd ( ) const

inline

dirty lines end

Returns: end line

Definition at line 86 of file katebuffer.h.

◆ editTagFrom()

bool KateBuffer::editTagFrom ( ) const

inline

line inserted/removed?

Returns: line inserted/removed?

Definition at line 95 of file katebuffer.h.

◆ editTagStart()

int KateBuffer::editTagStart ( ) const

inline

dirty lines start

Returns: start line

Definition at line 77 of file katebuffer.h.

◆ ensureHighlighted()

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 229 of file katebuffer.cpp.

◆ invalidateHighlighting()

void KateBuffer::invalidateHighlighting ( )

Invalidate highlighting of whole buffer.

Definition at line 308 of file katebuffer.cpp.

◆ isFoldingStartingOnLine()

std::pair< bool, bool > KateBuffer::isFoldingStartingOnLine ( int startLine )

For a given line, compute if folding starts here.

Parameters

startLine start line

Returns: does folding start here and is it indentation based?

Definition at line 393 of file katebuffer.cpp.

◆ openFile()

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 111 of file katebuffer.cpp.

◆ plainLine()

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.

◆ saveFile()

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 202 of file katebuffer.cpp.

◆ setHighlight()

void KateBuffer::setHighlight ( int hlMode )

Use highlight for highlighting.

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

Definition at line 279 of file katebuffer.cpp.

◆ tagLines

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

signal

Emitted when the highlighting of a certain range has changed.

◆ tooLongLinesWrapped()

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.

◆ unwrapLine()

void KateBuffer::unwrapLine ( int line )

overridevirtual

Unwrap given line.

Parameters

line	line to unwrap

Reimplemented from Kate::TextBuffer.

Definition at line 258 of file katebuffer.cpp.

◆ updateHighlighting()

void KateBuffer::updateHighlighting ( )

Update highlighting of the lines in last edit transaction.

Definition at line 80 of file katebuffer.cpp.

◆ wrapLine()

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 248 of file katebuffer.cpp.
