      public UninitializedSegment(SegmentFile file, long segmentId, int maxSegmentSize, MappedByteBuffer buffer, io.camunda.zeebe.journal.file.JournalIndex journalIndex)
      Creates an instance of a UninitializedSegment record class.
      Parameters:
      file - the value for the file record component
      segmentId - the value for the segmentId record component
      maxSegmentSize - the value for the maxSegmentSize record component
      buffer - the value for the buffer record component
      journalIndex - the value for the journalIndex record component

  • Method Details

    • initializeForUse

      public io.camunda.zeebe.journal.file.Segment initializeForUse(long index, long lastWrittenAsqn, io.camunda.zeebe.journal.file.JournalMetrics metrics)
      Creates a proper, initialized segment by writing a SegmentDescriptor with the given index.

    • 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.

      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.

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

    • maxSegmentSize

      public int maxSegmentSize()
      Returns the value of the maxSegmentSize record component.
      Returns:
