public abstract class AbstractMRNodeTrafficController
extends AbstractMRTrafficController

Abstract Traffic Controller base class for those implementations that track a set of nodes.

The nodes are descendents of AbstractNode. Provides node management services, but no additional protocol.

Field Details

minNode

protected int minNode

maxNode

protected int maxNode

numNodes

protected volatile int numNodes

Total number of SerialNodes registered with this TrafficController. Incremented as Serial Nodes are created and registered. Corresponds to the next available address in nodeArray.

nodeArray

protected AbstractNode[] nodeArray

curSerialNodeIndex

protected int curSerialNodeIndex

Working variable for keeping track of the active node, if any.

Constructor Details

AbstractMRNodeTrafficController

public AbstractMRNodeTrafficController()

Create a new unnamed MRNodeTrafficController instance.

Method Details

init

protected void init(int minNode,
 int maxNode)

Initialize based on number of first and last nodes.

Parameters:

minNode - lowest node number, usually 0

maxNode - highest node number

getMustInit

protected boolean getMustInit(int i)

Does a given node need to have initialization data sent?

Parameters:

i - the node address (number)

Returns:

true if initialization data is required

setMustInit

protected void setMustInit(int i,
 boolean v)

Mark whether a given node needs to have initialization data sent.

Parameters:

i - the node index

v - true if set to require sending initialization data

setMustInit

protected void setMustInit(AbstractNode node,
 boolean v)

getNumNodes

public int getNumNodes()

Get the total number of currently registered nodes.

Returns:

the number of registerd nodes on this connection

registerNode

public void registerNode(AbstractNode node)

Register a Serial node on this TrafficController.

Parameters:

node - the node object to register

getNode

public AbstractNode getNode(int index)

Get the Serial node for a given index as registered with this TrafficController.

Parameters:

index - the index number of the node. To cycle through all nodes, begin with index=0, and increment your index at each call.

Returns:

the node at index, 'null' when index exceeds the number of defined nodes

getNodeFromAddress

public AbstractNode getNodeFromAddress(int addr)

Identify a SerialNode from its node address.

Parameters:

addr - the node address, numbered from 0

Returns:

the node at node address, 'null' if a SerialNode with the specified address was not found

deleteNode

public void deleteNode(int nodeAddress)

Delete a SerialNode by node address.

Parameters:

nodeAddress - address number for the node to be deleted
