Defines a Polling Channel Adapter for the
'org.springframework.integration.stream.CharacterStreamReadingMessageSource'
that reads from stdin (System.in).
The charset to use when converting the byte stream from stdin to
String.
When 'true' an application event is published when EOF is detected
on stdin. To facilitate this, the poller thread will block until data is
present or EOF is detected.
Configures a Consumer Endpoint for the
'org.springframework.integration.stream.CharacterStreamWritingMessageHandler' that writes to stdout
(System.out) or to stderr (System.err) depending on the element name.
Specifies the order for invocation when this endpoint is connected as a
subscriber to a SubscribableChannel.
