Method Detail

setConnectionFilter

public void setConnectionFilter(ConnectionFilter filter)

Set a connection filter for this ConnectionManager instance. The filter is used to handle IP level allow/deny of incoming connections.

Parameters:

filter - ConnectionFilter instance.

getConnectionFilter

public ConnectionFilter getConnectionFilter()

Gets the active ConnectionFilter instance or returns null if no filter is set.

Returns:

the managers ConnectionFilter.

openConnectionCount

public int openConnectionCount()

Returns the number of open connections.

Returns:

the number of open connections as int.

getConnection

public Connection getConnection(int idx)

Returns the Connection at the given index.

Parameters:

idx -

Returns:

getConnectionsByAdddress

public Connection[] getConnectionsByAdddress(java.net.InetAddress addr)

Get all Connection instances with the given InetAddress.

Returns:

all Connection instances with the given InetAddress.

start

public void start()

Starts this ConnectionManager.

stop

public void stop()

Stops this ConnectionManager.

makeConnection

public void makeConnection(java.net.Socket insock)

Method that that tries to connect an incoming request. Properly queueing.

Parameters:

insock - Socket thats representing the incoming connection.

run

public void run()

Periodically does following work:

• cleaning up died connections.
• checking managed connections if they are working properly.
• checking the open connections.

Specified by:

run in interface java.lang.Runnable

registerClosedConnection

public void registerClosedConnection(Connection con)

Called by connections that got broken (i.e. I/O errors). The housekeeper will properly close the connection, and take care for misc necessary cleanup.

Parameters:

con - the connection that is broken. public void registerBrokenConnection(Connection con) { if (!m_BrokenConnections.contains(con) && !m_ClosedConnections.contains(con)) { log.debug("registerBrokenConnection()::" + con.toString()); m_BrokenConnections.push(con); } }//registerBrokenConnection
