Other features:
is_connected: BOOLEAN
effective function
True if the stream is connected.
disconnect
effective procedure
Try to disconnect the stream.
end_of_input: BOOLEAN
effective function
end_of_input means the previous attempt in character reading failed because the end has been reached.
can_unread_character: BOOLEAN
effective function
can_disconnect: BOOLEAN
constant attribute
True if the stream can be safely disconnected (without data loss, etc.)
detach
effective procedure
Detach the input and the ouput
See also detach_input, detach_output.
is_filtered: BOOLEAN
effective function
Is one of the input or output streams filtered?
set_filter (a_filter: FILTER)
effective procedure
Don't use (use set_input_filter or set_output_filter)
can_read_character: BOOLEAN
constant attribute
Note that this state is usually temporary.
can_read_line: BOOLEAN
constant attribute
valid_last_character: BOOLEAN
constant attribute
read_character
effective procedure
If read_character fail, end_of_input is set.
read_line_in (buffer: STRING)
effective procedure
Same job as read_line but storage is directly done in buffer.
read_available_in (buffer: STRING, limit: INTEGER_32)
effective procedure
Same job as read_available but storage is directly done in buffer.

effective procedure
last_character: CHARACTER
effective function

effective function
descriptor: INTEGER_32
effective function
Some OS-dependent descriptor.
has_descriptor: BOOLEAN
effective function
True if that stream can be associated to some OS-meaningful descriptor.
skip_separators
effective procedure
Skip all separators (see is_separator of class CHARACTER) and make the first non-separator available in last_character.
skip_separators_using (separators: STRING)
effective procedure
Same job as skip_separators using the separators set.
skip_remainder_of_line
effective procedure

read_integer
effective procedure
Read an integer according to the Eiffel syntax.
last_integer: INTEGER_32

Last integer read using read_integer.
valid_last_integer: BOOLEAN
writable attribute
Was the last call to read_integer successful ?
last_real: REAL_64
writable attribute
Last real read with read_real.
valid_last_real: BOOLEAN
writable attribute
Was the last call to read_real successful ?
read_real
effective procedure
Read a REAL and make the result available in last_real.
last_string: STRING
once function
Access to the unique common buffer to get for example the result computed by read_line, read_word, newline, etc.
read_line
effective procedure
Read a complete line ended by '%N' or end_of_input.%
read_available (limit: INTEGER_32)
effective procedure
Read as many characters as possible, as long as the stream does not block and up to the given limit.
read_word
effective procedure
Read a word using is_separator of class CHARACTER.
newline
effective procedure
Consume input until newline ('%N') is found.
reach_and_skip (keyword: STRING)
effective procedure
Try to skip enough characters in order to reach the keyword which is skipped too.
