io.atomix.raft.storage.log.entry.SerializedApplicationEntry
All Implemented Interfaces:
ApplicationEntry, RaftEntry
public record SerializedApplicationEntry(long lowestPosition, long highestPosition, org.agrona.DirectBuffer data) extends Record implements ApplicationEntry
Stores an entry that contains serialized records, ordered by their position; the lowestPosition and highestPosition metadata allow for fast binary search over a collection of entries to quickly find a particular record.

  • Method Details

    • toSerializable

      public BufferWriter toSerializable(long term, RaftEntrySerializer serializer)
      Specified by:
      toSerializable in interface RaftEntry

    • dataWriter

      public BufferWriter dataWriter()
      Specified by:
      dataWriter in interface ApplicationEntry

    • 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 '=='.
      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.

    • lowestPosition

      public long lowestPosition()
      Returns the value of the lowestPosition record component.
      Specified by:
      lowestPosition in interface ApplicationEntry
      Returns:
      the value of the lowestPosition record component

    • highestPosition

      public long highestPosition()
      Returns the value of the highestPosition record component.
      Specified by:
      highestPosition in interface ApplicationEntry
      Returns:
      the value of the highestPosition record component

    • data

      public org.agrona.DirectBuffer data()
      Returns the value of the data record component.
      Returns:
      the value of the data record component
