Member Function Documentation

◆ expandCapacity()

void LINE_READER::expandCapacity ( unsigned aNewsize)
protected

Will expand the capacity of line up to maxLineLength but not greater, so be careful about making assumptions of capacity after calling this.

Definition at line 170 of file richio.cpp.

References m_capacity, m_length, m_line, and m_maxLineLength.

Referenced by FILE_LINE_READER::ReadLine(), INPUTSTREAM_LINE_READER::ReadLine(), and STRING_LINE_READER::ReadLine().

◆ GetSource()

virtual const wxString & LINE_READER::GetSource ( ) const
inlinevirtual

Returns the name of the source of the lines in an abstract sense.

This may be a file or it may be the clipboard or any other source of lines of text. The returned string is useful for reporting error messages.

◆ Length()

unsigned LINE_READER::Length ( ) const
inline

Return the number of bytes in the last line read from this LINE_READER.

Definition at line 155 of file richio.h.

References m_length.

◆ Line()

char * LINE_READER::Line ( ) const
inline

Return a pointer to the last line that was read in.

◆ LineNumber()

virtual unsigned LINE_READER::LineNumber ( ) const
inlinevirtual

Return the line number of the last line read from this LINE_READER.

Lines start from 1.

Reimplemented in FILTER_READER, and WHITESPACE_FILTER_READER.

◆ operator char *()

LINE_READER::operator char * ( ) const
inline

A casting operator that returns a char* pointer to the start of the line buffer.

Definition at line 137 of file richio.h.

References Line().

◆ ReadLine()

virtual char * LINE_READER::ReadLine ( )
pure virtual

Read a line of text into the buffer and increments the line number counter.

If the line is larger than the maximum length passed to the constructor, then an exception is thrown. The line is nul terminated.

Returns
The beginning of the read line, or NULL if EOF.
Exceptions
IO_ERRORwhen a line is too long.

Implemented in BLOB_READER, FILE_LINE_READER, FILTER_READER, INPUTSTREAM_LINE_READER, STDISTREAM_LINE_READER, STRING_LINE_READER, and WHITESPACE_FILTER_READER.
