Package com.yahoo.vdslib.state

Class NodeState

java.lang.Object
com.yahoo.vdslib.state.NodeState
All Implemented Interfaces:
Cloneable
public class NodeState extends Object implements Cloneable
The state of a single node in the cluster state TODO: The config aspects of this should move to ConfiguredNode TODO: The type should be removed, as it is part of the owner. TODO: Monitoring aspects should move to NodeInfo

  • Constructor Details

  • Method Details

    • getListingBucketsInitProgressLimit

      public static float getListingBucketsInitProgressLimit()

    • clone

      public NodeState clone()
      Overrides:
      clone in class Object

    • above

      public boolean above(NodeState other)
      A state can not be forced to be in a state above its reported state. For instance, a node being down cannot be forced to up, but a node being down can be forced to maintenance.

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • similarTo

      public boolean similarTo(Object o)
      States are similar if the cluster state doesn't need to be updated due to a change. Note that min dist bits may need to alter cluster state, but as we don't know at this point, we ignore it. Cluster state will check for that.

    • similarToIgnoringInitProgress

      public boolean similarToIgnoringInitProgress(NodeState other)

    • getDiff

      public Diff getDiff(NodeState other)

    • getTextualDifference

      public String getTextualDifference(NodeState other)

    • setCapacity

      public NodeState setCapacity(float c)
      Capacity is set by deserializing a node state. This seems odd, as it is config

    • setInitProgress

      public NodeState setInitProgress(float p)

    • setDescription

      public NodeState setDescription(String desc)

    • setMinUsedBits

      public NodeState setMinUsedBits(int u)

    • setState

      public NodeState setState(State state)

    • setStartTimestamp

      public NodeState setStartTimestamp(long ts)

    • getCapacity

      public double getCapacity()

    • getInitProgress

      public double getInitProgress()

    • hasDescription

      public boolean hasDescription()

    • getDescription

      public String getDescription()

    • getState

      public State getState()

    • getMinUsedBits

      public int getMinUsedBits()

    • getStartTimestamp

      public long getStartTimestamp()

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • toString

      public String toString(boolean compact)

    • serialize

      public String serialize()

    • serialize

      public String serialize(boolean verbose)

    • serialize

      public String serialize(int nodeIdx, boolean verbose)

    • deserialize

      public static NodeState deserialize(NodeType type, String serialized) throws ParseException
      Creates an instance from the serialized form produced by serialize
      Throws:
      ParseException

    • verifyValidInSystemState

      public void verifyValidInSystemState(NodeType type)
