#include <readonlytextfilestream.h>

Class Description

ReadonlyTextFileStream is only used for opening text file in read-only mode.

It's equivalent to use FileStream when opening files in "rt" mode. But FileStream is very slow when reading files. So we optimize the original codes in FileStream and create this new class which is thousand times faster for reading text files than FileStream.

Note: Invoke any non-read-only methods in ReadonlyTextFileStream will result in a runtime exception. Such methods include putch(),puts(),printf().

ScripterExport ~ReadonlyTextFileStream ( )

The default destructor.

ScripterExport ReadonlyTextFileStream* open	(	const MCHAR *	ifile_name,
		unsigned int	encoding = `-1`
	)

Open a new text file.

Parameters

[in]	ifile_name	The file name.
[in]	encoding	The encoding to use if if can not be determined from the file contents, If -1, a default encoding based on the file language setting in Preference /Files (exposed through Interface14) will be used.

Returns: The ReadonlyTextFileStream instance itself if max is able to open the file or undefined if it fails.
