Class TInput
Instances of TInput represent an input stream for
reading strings from a source. TInput is only used
as base class for other classes. It is not possible to create instances
of it.
close
Closes the input stream represented by the object.
|
copyTo output [byteCount]
Copies the contents of the stream into an output stream.
|
readln
Reads a line from the input stream represented by the object.

close
TInput close
Closes the input stream represented by the object.
- Returns:
-
A reference to the object it was called for.
-
Closing the stream releases all the underlying operating system
resources. After closing the stream no more methods may be called.
copyTo
TInput copyTo output [byteCount]
Copies the contents of the stream into an output stream.
- Parameters:
- output -
An object that must responde to a write method.
- byteCount -
Integer representing the maximum number of bytes to copy into the
the output stream.
- Returns:
-
A reference to the object it was called for.
-
The output object received as argument is expected
to respond to a write method that receives a byte
array for argument.
This method works by reading a block from the underlying input stream
and passing it to output by calling its
write method. It repeats this two steps until an end
of file condition is reached in the input stream or until
byteCount bytes are read from the input stream. If
there is no byteCount argument then the copy proceeds
until the end of file on the input stream.
readln
TInput readln
Reads a line from the input stream represented by the object.
- Returns:
-
The string containing the line that was read. The null object if
the stream is at end of file.
