Node

public Node()

Constructor

Node

public Node(ProtocolStack stack)

Constructor
Note: the protocol stack object actually deployed on the node is a copy of the stack passed as argument. Therefore, any changes in the object after invoking this method do not have any effect on the stack deployed on the node.

Parameters:

stack - The protocol stack of the node.

Method Detail

getProtocolStack

public ProtocolStack getProtocolStack()

Return the protocol stack deployed on the node

Returns:

the ProtocolStack object, if present. Otherwise, null is returned.

See Also:

ProtocolStack

setProtocolStack

public void setProtocolStack(ProtocolStack stack)

Deploy the specified protocol stack on the node. If node there is already a protocol stack with the same name deployed, that is overwritten.
Note: the protocol stack object actually deployed on the node is a copy of the stack passed as argument. Therefore, any changes in the object after invoking this method do not have any effect on the stack deployed on the node.

Parameters:

stack - The protocol stack to deploy

See Also:

ProtocolStack

removeProtocolStack

public void removeProtocolStack()

Removes the protocol stack deployed on the node, if any. It is equivalent to set the protocol stack to null with the setProtocolStack method.

See Also:

setProtocolStack(ProtocolStack)

getApplication

public Application getApplication(String name)

Return the application with the specified name

Parameters:

name - the name of the application

Returns:

the Application object, if present. Otherwise, null is returned.

Application

getAllApplications

public Set<String> getAllApplications()

Return a set containing all the application names. To get the object of a specific application use getApplication(String)

Returns:

a set with all names of applications deployed on this node

See Also:

getApplication(String)

setApplication

public void setApplication(Application application)

Deploy the specified application on the node. If node there is already an application with the same name deployed, that is overwritten.
Note: the application object actually deployed on the node is a copy of the application passed as argument. Therefore, any changes in the object after invoking this method do not have any effect on the application deployed on the node.

Parameters:

application - The application to deploy

See Also:

Application

removeApplication

public Application removeApplication(String name)

Remove a specific application from the node

Parameters:

name - The name of the application to remove

Returns:

The removed Application object, if was present on the node. Otherwise null is returned.

clone

public Node clone()

Return a copy of this object

Overrides:

clone in class PropertyContainer

Returns:

A copy of this object
