All Known Implementing Classes:

public interface NodeInstance
extends SandInstanceMessage

A declaration of a node instance.

If you are declaring a new node Foo, then you create the FooNodeDecl.java (declaration) and FooNode.java (implementation) files. The generators create FooNodeBase.java (the SAND implementation), and FooNodeInstance.java (the instance declaration). FooNodeInstance implements NodeInstance. A deployment Configuration contains a collection of NodeInstances, which comprise the deployed system.

setLogLevel

void setLogLevel(int logLevel)

Set the log level of this node. Must be one of the Logger.LOGLEVEL_* values.

getHelperNodes

NodeInstance[] getHelperNodes()

Return the helper node instances configured to work with this node instance.

setHelperNodes

void setHelperNodes(NodeInstance[] nodes)
