Method Detail

handle

public org.graalvm.shadowed.org.jline.terminal.Terminal.SignalHandler handle(org.graalvm.shadowed.org.jline.terminal.Terminal.Signal signal,
                                                                             org.graalvm.shadowed.org.jline.terminal.Terminal.SignalHandler handler)

Description copied from interface: org.graalvm.shadowed.org.jline.terminal.Terminal

Registers a handler for the given Terminal.Signal.

Note that the JVM does not easily allow catching the Terminal.Signal.QUIT signal, which causes a thread dump to be displayed. This signal is mainly used when connecting through an SSH socket to a virtual terminal.

Specified by:

handle in interface org.graalvm.shadowed.org.jline.terminal.Terminal

Overrides:

handle in class AbstractTerminal

Parameters:

signal - the signal to register a handler for

handler - the handler

Returns:

the previous signal handler

reader

public NonBlockingReader reader()

Description copied from interface: org.graalvm.shadowed.org.jline.terminal.Terminal

Retrieve the Reader for this terminal. This is the standard way to read input from this terminal. The reader is non blocking.

Returns:

The non blocking reader

writer

public PrintWriter writer()

Description copied from interface: org.graalvm.shadowed.org.jline.terminal.Terminal

Retrieve the Writer for this terminal. This is the standard way to write to this terminal.

Returns:

The writer

input

public InputStream input()

Description copied from interface: org.graalvm.shadowed.org.jline.terminal.Terminal

Retrieve the input stream for this terminal. In some rare cases, there may be a need to access the terminal input stream directly. In the usual cases, use the Terminal.reader() instead.

Returns:

The input stream

See Also:

Terminal.reader()

output

public OutputStream output()

Description copied from interface: org.graalvm.shadowed.org.jline.terminal.Terminal

Retrieve the output stream for this terminal. In some rare cases, there may be a need to access the terminal output stream directly. In the usual cases, use the Terminal.writer() instead.

Returns:

The output stream

See Also:

Terminal.writer()

doClose

protected void doClose()
                throws IOException

Overrides:

doClose in class AbstractPosixTerminal

Throws:

IOException
