Record Class DistributedMap.WriteMetadata

java.lang.Object
java.lang.Record
com.loomcache.server.datastructures.DistributedMap.WriteMetadata
Record Components:
timestampMillis - wall-clock write time (System.currentTimeMillis())
writerNodeId - deterministic identifier of the node that wrote the value (typically clusterId + ":" + nodeId)
Enclosing class:
DistributedMap<K,V>
public static record DistributedMap.WriteMetadata(long timestampMillis, String writerNodeId) extends Record
Per-key metadata describing which node/time last wrote the value. Used by WAN merge paths to break same-millisecond ties deterministically and to suppress echo loops when the incoming value equals the local value.

  • Constructor Details

    • WriteMetadata

      public WriteMetadata(long timestampMillis, String writerNodeId)
      Creates an instance of a WriteMetadata record class.
      Parameters:
      timestampMillis - the value for the timestampMillis record component
      writerNodeId - the value for the writerNodeId record component

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • timestampMillis

      public long timestampMillis()
      Returns the value of the timestampMillis record component.
      Returns:
      the value of the timestampMillis record component

    • writerNodeId

      public String writerNodeId()
      Returns the value of the writerNodeId record component.
      Returns:
      the value of the writerNodeId record component
