Class ProxyConnectionManager

java.lang.Object

org.jivesoftware.openfire.filetransfer.proxy.ProxyConnectionManager

public class ProxyConnectionManager
extends Object

Manages the connections to the proxy server. The connections go through two stages before file transfer begins. The first stage is when the file transfer target initiates a connection to this manager. Stage two is when the initiator connects, the manager will then match the two connections using the unique SHA-1 hash defined in the SOCKS5 protocol.

Field Summary

Fields

Modifier and Type	Field	Description
static SystemProperty<Integer>	EXECUTOR_CORE_POOL_SIZE	The number of threads to keep in the thread pool that powers proxy (SOCKS5) connections, even if they are idle.
static SystemProperty<Integer>	EXECUTOR_MAX_POOL_SIZE	The maximum number of threads to allow in the thread pool that powers proxy (SOCKS5) connections.
static SystemProperty<Duration>	EXECUTOR_POOL_KEEP_ALIVE	The number of threads in the thread pool that powers proxy (SOCKS5) connections is greater than the core, this is the maximum time that excess idle threads will wait for new tasks before terminating.

Method Detail

getProxyPort

public int getProxyPort()

createDigest

public static String createDigest(String sessionID,
                                  org.xmpp.packet.JID initiator,
                                  org.xmpp.packet.JID target)

Creates the digest needed for a byte stream. It is the SHA1(sessionID + initiator + target).

Parameters:

sessionID - The sessionID of the stream negotiation

initiator - The initiator of the stream negotiation

target - The target of the stream negotiation

Returns:

SHA-1 hash of the three parameters

isRunning

public boolean isRunning()

disable

public void disable()
