Interface ChannelCondition

public interface ChannelCondition

Contains constants that can be used to specify what conditions to wait for on a SSH-2 channel (e.g., represented by a Session).
See Also:
Session.waitForCondition(int,long)

Field Summary

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 Details

CLOSED

public static final int CLOSED
The underlying SSH-2 channel, however not necessarily the whole connection, has been closed. This implies EOF. Note that there may still be unread stdout or stderr data in the local window, i.e, STDOUT_DATA or/and STDERR_DATA may be set at the same time.
Field Value:
2

EOF

public static final int EOF
EOF on has been reached, no more _new_ stdout or stderr data will arrive from the remote server. However, there may be unread stdout or stderr data, i.e, STDOUT_DATA or/and STDERR_DATA may be set at the same time.
Field Value:
16

EXIT_SIGNAL

public static final int EXIT_SIGNAL
The exit signal of the remote process is available.
Field Value:
64

EXIT_STATUS

public static final int EXIT_STATUS
The exit status of the remote process is available. Some servers never send the exist status, or occasionally "forget" to do so.
Field Value:
32

STDERR_DATA

public static final int STDERR_DATA
There is stderr data available that is ready to be consumed.
Field Value:
8

STDOUT_DATA

public static final int STDOUT_DATA
There is stdout data available that is ready to be consumed.
Field Value:
4

TIMEOUT

public 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).
Field Value:
1
