Constructor Detail

Period

public Period(NodeId self_node_id,
              int basePeriod,
              String op,
              int factor,
              long timeout)

Method Detail

getBasePeriod

public int getBasePeriod()

getOp

public int getOp()

getFactor

public int getFactor()

setPeriod

public void setPeriod(int basePeriod,
                      String op,
                      int factor)

setPeriod

public void setPeriod(int basePeriod,
                      int op,
                      int factor)

changePeriod

public boolean changePeriod(NodeId node,
                            int level)

removeNode

public void removeNode(NodeId node)

getPeriod

public long getPeriod(NodeId node)

getPeriod

public long getPeriod(int level)

getTimeout

public long getTimeout(NodeId node)

Get what the timeout value should be for a node. NOTE: Each instance of a Period shares its table of timeouts with all other Periods used by the same NodeId. That means, for example, a LossPatch and LatencyPatch within the same Patchwork look at the same timeout values.

setTimeout

public void setTimeout(NodeId node,
                       long value)

Set what the timeout value should be for a node. NOTE: Each instance of a Period shares its table of timeouts with all other Periods used by the same NodeId. That means, for example, a LossPatch and LatencyPatch within the same Patchwork look at the same timeout values. THIS MEANS IF YOU SET IT, ALL OTHER PATCHES ON YOUR NODE WILL SEE IT.
