◆ LineNumber()

◆ operator char *()

LINE_READER::operator char * ( ) const
inlineinherited

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

Definition at line 137 of file richio.h.

◆ ReadLine()

char * STDISTREAM_LINE_READER::ReadLine ( )
overridevirtual

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.

Implements LINE_READER.

◆ SetStream()

void STDISTREAM_LINE_READER::SetStream ( std::istream &  aStream)

Set the stream for this line reader.

Parameters
aStreama stream to read
