Record Class ConsistencyGroupId

java.lang.Object
java.lang.Record
com.loomcache.server.cp.ConsistencyGroupId
Record Components:
name - the human-readable name of the group (e.g., "locks", "counters", "latches"), must not be null or empty
groupId - the unique numeric identifier for this group (typically auto-assigned), must be non-negative
All Implemented Interfaces:
Serializable
public record ConsistencyGroupId(String name, long groupId) extends Record implements Serializable
Identifies a Consistency group (Consistent/Partition-tolerant group) with a name and unique ID.

Purpose: Consistency groups are logical divisions managed by the Consistency Subsystem for Raft-based strong consistency. This record uniquely identifies each group via the combination of (name + groupId).

Thread Safety: This record is immutable and thread-safe. Multiple threads can safely share instances without synchronization.

Serialization: This record is serializable for distributed storage and network transmission.

    • toString

      public 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()

    • 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.
