\doxysubsection{Detailed Description}
The Read\+Only\+File class allows Qore programs to read existing files. 

\begin{DoxyParagraph}{Restrictions\+:}
\doxylink{group__parse__options_ga5e466ed886222f0b57b0a399b455be71}{Qore\+::\+PO\+\_\+\+NO\+\_\+\+FILESYSTEM}
\end{DoxyParagraph}
\begin{DoxyNote}{Note}
This class is not available with the \doxylink{group__parse__options_ga5e466ed886222f0b57b0a399b455be71}{PO\+\_\+\+NO\+\_\+\+FILESYSTEM} parse option
\end{DoxyNote}
Read\+Only\+File objects are opened with a specific \doxylink{character_encoding}{character encoding}, meaning that any string read from the file will be tagged with the file\textquotesingle{}s \doxylink{character_encoding}{character encoding}. If no \doxylink{character_encoding}{character encoding} is specified, then the \doxysectlink{character_encoding_default_encoding}{default character encoding}{1} is assumed for the file.

This class supports posting read events to a \doxylink{class_qore_1_1_thread_1_1_queue}{Queue}. See \doxylink{event_handling}{I/O Event Handling} for more information.

Opens a file in a particular mode; throws an exception on failure. 

Opens the file in the mode given; if the Read\+Only\+File was previously open, it is closed first. Optionally the Read\+Only\+File\textquotesingle{}s default character encoding can be specified.

Note that if no encoding is specified, the Read\+Only\+File will be tagged with the \doxylink{character_encoding}{character encoding} set in the Read\+Only\+File\textquotesingle{}s \doxylink{class_qore_1_1_abstract_pollable_io_object_base_a772a2dc97dddb19a647ccdc863068d57}{constructor}.

If an error occurs, a {\ttfamily READONLYFILE-\/\+OPEN-\/\+ERROR} exception is thrown.

Reads a certain number of characters from the Read\+Only\+File within an optional timeout period and returns a string of the data read or \doxysectlink{basic_data_types_nothing}{NOTHING}{1} if no data can be read. 

Reads a certain amount of string data from the Read\+Only\+File; the size argument is required. To read binary data, use the \doxylink{class_qore_1_1_read_only_file_ac9513b569846b16e2b7363df5ba9f647}{Read\+Only\+File\+::read\+Binary()} method.

Note that the amount of data read from the file may be less than the size given, for example if the file does not contain enough data to fulfill the request. In this case, only the data available in the file is returned.

An optional timeout period in milliseconds can be passed as well (or a \doxysectlink{basic_data_types_relative_dates}{relative date/time value}{2} may be passed instead of an integer to make the timeout units clear; ex\+: {\ttfamily 25ms}). If a timeout value is passed and the data cannot be read within the timeout period, then a {\ttfamily READONLYFILE-\/\+READ-\/\+TIMEOUT} exception is thrown. If no timeout value is passed or a negative value is given, then the call will never timeout until either the requested amount of data has been read from the Read\+Only\+File or an end-\/of-\/file condition has been reached.
