33 //! This class provides a tool for constructing the parametrized message
34 //! basing on resources loaded by Message_MsgFile tool.
35 //!
36 //! A Message is created from a keyword: this keyword identifies the
37 //! message in a message file that should be previously loaded by call
38 //! to Message_MsgFile::LoadFile().
39 //!
40 //! The text of the message can contain placeholders for the parameters
41 //! which are to be filled by the proper values when the message
42 //! is prepared. Most of the format specifiers used in C can be used,
43 //! for instance, %s for string, %d for integer etc. In addition,
44 //! specifier %f is supported for double numbers (for compatibility
45 //! with previous versions).
46 //!
47 //! User fills the parameter fields in the text of the message by
48 //! calling corresponding methods Arg() or operators .
49 //!
50 //! The resulting message, filled with all parameters, can be obtained
51 //! by method Get(). If some parameters were not filled, the text
52 //! UNKNOWN is placed instead.
