Class Connections

java.lang.Object
  org.mobicents.media.server.connection.Connections

Direct Known Subclasses:

LocalToRemoteConnections, RemoteToRemoteConnections

public class Connections
extends Object

Implements connection management subsystem. Procedure of joining endponts must work very fast however dynamic connection creation upon request cause long and unpredictable delays. Preallocated connection objects gives better result.

Constructor Detail

Connections

public Connections(BaseEndpointImpl endpoint,
                   int localPoolSize,
                   int rtpPoolSize,
                   Boolean isLocalToRemote)
            throws Exception

Creates new connections subsystem.

Parameters:

endpoint - the endpoint running connections

poolSize - the number of available connections.

Throws:

Exception

Method Detail

getEndpoint

public BaseEndpointImpl getEndpoint()

getActiveConnectionsCount

public int getActiveConnectionsCount()

createConnection

public Connection createConnection(ConnectionType type)
                            throws ResourceUnavailableException

Creates connection with specified type.

Parameters:

type - the type of connection

Returns:

connection instance.

Throws:

ResourceUnavailableException

releaseConnection

public void releaseConnection(BaseConnection connection,
                              ConnectionType type)

release

public void release()

Closes all activities connections.

getMixer

public Mixer getMixer(MediaType mediaType)

Get access to the mixer.

Parameters:

mediaType - the type of the mixer: audio or video

Returns:

mixer component

getSplitter

public Splitter getSplitter(MediaType mediaType)

Gets access to the splitter.

Parameters:

mediaType - the type of the splitter: audio or video

Returns:

splitter component.

updateMode

public void updateMode(MediaType mediaType)
                throws ModeNotSupportedException

Determines transmission mode between endpoint and connections. This method is called when mode of any connection has been changed. It checks modes of all active connections and determines endpoint transition mode as a combination of connections modes.

Throws:

ModeNotSupportedException

getChannelId

protected String getChannelId(BaseConnection c1,
                              BaseConnection c2)

addToConference

protected void addToConference(BaseConnection connection)

updateConnectionChannels

protected void updateConnectionChannels(BaseConnection connection)

removeFromConference

protected void removeFromConference(BaseConnection connection)

report

public String report()

getCheckPoint

public CheckPoint getCheckPoint(MediaType mediaType,
                                int n)

Reads data from specified check point.

Parameters:

n - the identifier of check point

Returns:

the data collected by checkpoint.
