Closes this input stream. After calling this function, one should not attempt to read any more characters from this stream.
The default implementation provided by the Reader class does nothing.
| IOException | - if an I/O error occurs. |
Reimplemented from jem::io::Reader.

Returns the next character, cast to an int, from this input stream. If the end of the stream has been reached, -1 is returned.
-1.| IOException | - if an I/O error occurs. |
Implements jem::io::TextInput.

Pushes back the character c, cast to an unsigned char, into this input stream. This character must have been previously extracted from the input stream by calling one of the read() member functions. The pushed back character will be the first character to be extracted from the input stream when one of the read() member functions is called.
Characters must be pushed back in the same order as they have been read; one is not allowed to alter the contents of the input stream.
If the character c has a negative value, this function does nothing.
Example:
| c | - the character to be pushed back. |
this->read() == c.| IOException | - if an I/O error occurs. |
Implements jem::io::TextInput.
