Public Member Functions

 LINE_READER (unsigned aMaxLineLength=LINE_READER_LINE_DEFAULT_MAX)
 Build a line reader and fixes the length of the maximum supported line length to aMaxLineLength.
 
virtual ~LINE_READER ()
 
virtual char * ReadLine ()=0
 Read a line of text into the buffer and increments the line number counter.
 
virtual const wxString & GetSource () const
 Returns the name of the source of the lines in an abstract sense.
 
char * Line () const
 Return a pointer to the last line that was read in.
 
 operator char * () const
 A casting operator that returns a char* pointer to the start of the line buffer.
 
virtual unsigned LineNumber () const
 Return the line number of the last line read from this LINE_READER.
 
unsigned Length () const
 Return the number of bytes in the last line read from this LINE_READER.
 

Protected Member Functions

void expandCapacity (unsigned aNewsize)
 Will expand the capacity of line up to maxLineLength but not greater, so be careful about making assumptions of capacity after calling this.
 

Protected Attributes

unsigned m_length
 no. bytes in line before trailing nul.
 
unsigned m_lineNum
 
char * m_line
 the read line of UTF8 text
 
unsigned m_capacity
 no. bytes allocated for line.
 
unsigned m_maxLineLength
 maximum allowed capacity using resizing.
 
wxString m_source
 origin of text lines, e.g. filename or "clipboard"
