QChar edbee::CharTextBuffer::charAt ( int offset ) const

virtual

Returns the character at the given character.

Parameters

offset the offset of the given character

Returns: the character at the given offset

Implements edbee::TextBuffer.

◆ emitTextChanged

virtual

Returns the length of the buffer.

Returns: the length of the given text

Implements edbee::TextBuffer.

◆ lineCount()

virtual int edbee::CharTextBuffer::lineCount ( )

inlinevirtual

this method should return an array with all line offsets. A line offset pointsto the START of a line So it does NOT point to a newline character, but it points to the first character AFTER the newline character

Implements edbee::TextBuffer.

◆ lineFromOffset()

int edbee::CharTextBuffer::lineFromOffset ( int offset )

virtual

Returns the line position at the given offset.

Parameters

offset the offset to retreive the line from

Returns: the line from the given offset

Implements edbee::TextBuffer.

LineOffsetVector& edbee::CharTextBuffer::lineOffsetList ( )

inline

Todo:: : Temporary debug method. REMOVE!!

◆ offsetFromLine()

int edbee::CharTextBuffer::offsetFromLine ( int line )

virtual

This method returns the offset of the given line.

Parameters

lin	the line to retrieve the offset from

Returns: the offset of the given line

Implements edbee::TextBuffer.

◆ rawAppend() [1/2]

void edbee::CharTextBuffer::rawAppend ( QChar c )

virtual

Append a single character to the buffer in raw mode.

Parameters

		int	dataLength
	)

virtual

Appends a buffer of text to the document.

Parameters

data	the data to append
dataLength	the number of bytes availble by the data pointer

Implements edbee::TextBuffer.

◆ rawAppendBegin()

void edbee::CharTextBuffer::rawAppendBegin ( )

virtual

virtual

Ends the 'raw' appending of data.

Implements edbee::TextBuffer.

◆ rawDataPointer()

QChar * edbee::CharTextBuffer::rawDataPointer ( )

virtual

This method returns the raw data pointer WARNING calling this method moves the gap of the gapvector to the end. Which could involve a lot of data moving.

Implements edbee::TextBuffer.

		int	length
	)		const

virtual

Returns the text part.

Parameters

pos	the position of the given text
length	the length of the text to get

Returns: returns a part of the text
