The TextOutput interface provides a set of (abstract) functions for writing characters and numbers to an output stream. It is typically used to implement functions that write text output and do not care about the destination of the output.
Many classes in jem provide an overloaded version of the << operator that writes the contents of a class instance in a human-readable format to a text output stream. These so-called print operators can be very useful debugging aids.

pure virtual |
Writes the integer c, cast to an unsigned char, to this output stream.
| c | - the character to be written. |
| IOException | - if an I/O error occurs. |
Implemented in jem::mt::ThreadSafeWriter, jem::io::PrintWriter, jem::StringBuffer, jem::io::PrefixWriter, jem::io::BufferedWriter, jem::io::OutputStreamWriter, jem::io::TeeWriter, jem::io::FilterWriter, jem::io::StringWriter, jem::io::StderrWriter, jem::io::StdoutWriter, and jem::io::NullWriter.
|
pure virtual |
Writes n copies of the integer c, cast to an unsigned char, to this output stream.
| c | - the character to be written. |
| n | - the number of copies of the character c to be written. |
n >= 0| IOException | - if an I/O error occurs. |
Implemented in jem::io::Writer.
|
pure virtual |
Writes the first n characters stored in the array buf to this output stream.
| buf | - a character array of which the length is at least n. |
| n | - the number of characters to be written. |
n >= 0 buf[0], ..., buf[n - 1] have been written to this output stream.| IOException | - if an I/O error occurs. |
Implemented in jem::io::Writer.

operator << ( TextOutput&, long ) Implemented in jem::io::Writer.
|
pure virtual |
Prints the double d, converted to a character string, to this output stream. You should normally not call this function directly, but use one of the overloaded print operators.
