Field Detail

node

public org.eclipse.hyades.internal.execution.local.control.Node node

The underlying node that retains the connection

Constructor Detail

NodeImpl

public NodeImpl(java.lang.String name)

Constructs a node implementation given the specified name

Method Detail

connect

public ISession connect(ConnectionSpecifier specifier)
                 throws UnknownDaemonException,
                        DaemonConnectException,
                        java.net.UnknownHostException

Connects to the node using this connection specifier

Specified by:

connect in interface INodeExtended

Parameters:

specifier - the specifier used for connection purposes, uniquely identifies an agent controller instance, only the port is read currently, the host is specified using the node's name at construction time, the host for this node is maintained immutable

Returns:

the session to this agent controller instance

Throws:

UnknownDaemonException

DaemonConnectException

java.net.UnknownHostException

connect

public ISession connect(java.lang.String daemonType,
                        java.security.Principal principal)
                 throws UnknownDaemonException,
                        DaemonConnectException,
                        java.net.UnknownHostException

Description copied from interface: INode

Open a session with the daemon. The specifics of this method are currently unresolved. It is expected that we will add an IConnection interface that will probably replace this method. Whatever methods take the place of this method are expected to throw a number of exception types. RKD: We need to specialize Principal to handle logins automatically within the framework.

Specified by:

connect in interface INode

Parameters:

daemonType - UNRESOLVED - it's unclear if this is the right place for this extension point.

principal - A specialized Principal object for authentication and login.

Returns:

an ISession on this INode

Throws:

UnknownDaemonException

DaemonConnectException

java.net.UnknownHostException

connect

public ISession connect(java.lang.String daemonType,
                        java.security.Principal principal,
                        int iterations)
                 throws UnknownDaemonException,
                        DaemonConnectException,
                        java.net.UnknownHostException

Throws:

UnknownDaemonException

DaemonConnectException

java.net.UnknownHostException

connectUsingLegacyMethod

public org.eclipse.hyades.internal.execution.local.control.Node connectUsingLegacyMethod(java.lang.String daemonType,
                                                                                         java.security.Principal principal)
                                                                                  throws UnknownDaemonException,
                                                                                         DaemonConnectException,
                                                                                         java.net.UnknownHostException

Obtains and connects to node using the legacy method (does not support secure connections)

Parameters:

daemonType - the port to connect to

principal - the security principal to use

Returns:

the node connected to

Throws:

java.lang.Exception

UnknownDaemonException
