Field Summary

Fields

Modifier and Type	Field and Description
static int	CLOSED The underlying SSH-2 channel, however not necessarily the whole connection, has been closed.
static int	EOF EOF on has been reached, no more _new_ stdout or stderr data will arrive from the remote server.
static int	EXIT_SIGNAL The exit signal of the remote process is available.
static int	EXIT_STATUS The exit status of the remote process is available.
static int	STDERR_DATA There is stderr data available that is ready to be consumed.
static int	STDOUT_DATA There is stdout data available that is ready to be consumed.
static int	TIMEOUT A timeout has occurred, none of your requested conditions is fulfilled.

Field Detail

TIMEOUT

static final int TIMEOUT

A timeout has occurred, none of your requested conditions is fulfilled. However, other conditions may be true - therefore, NEVER use the "==" operator to test for this (or any other) condition. Always use something like ((cond & ChannelCondition.CLOSED) != 0).
