Description

Text input stream implementation for reading from stdin.

Implementations for the TextInputStream methods throw FileIOError on any I/O error.

Member Function Documentation

void gmx::StandardInputStream::close ( )

inlineoverridevirtual

Closes the stream.

It is not allowed to read from a stream after it has been closed. See TextOutputStream::close() for rationale for a close() method separate from the destructor. For input, failures during close should be rare, but it is clearer to keep the interface symmetric.

Implements gmx::TextInputStream.

bool gmx::StandardInputStream::isInteractive ( )

static

Returns whether stdin is an interactive terminal.

Only works on Unix, otherwise always returns true.

Does not throw.

bool gmx::StandardInputStream::readLine ( std::string *  line )

overridevirtual

Reads a line (with newline included) from the stream.

Parameters

[out]

line

String to receive the line.

Returns

false if nothing was read because the stream ended.

On error or when false is returned, line will be empty.

Implements gmx::TextInputStream.
