- - ### Field Detail

    - #### LENGTH

          public static final int LENGTH

        Constant Field Values

  - ### Method Detail

    - #### getLocalId

          public static CounterId getLocalId()

    - #### fromInt

          public static CounterId fromInt(int n)

      Function for test purposes, do not use otherwise. Pack an int in a valid CounterId so that the resulting ids respects the numerical ordering. Used for creating handcrafted but easy to understand contexts in unit tests (see CounterContextTest).

    - #### wrap

          public static CounterId wrap(java.nio.ByteBuffer id)

    - #### wrap

          public static CounterId wrap(java.nio.ByteBuffer bb,
                       int offset)

    - #### generate

          public static CounterId generate()

    - #### bytes

          public java.nio.ByteBuffer bytes()

    - #### isLocalId

          public boolean isLocalId()

    - #### compareTo

          public int compareTo(CounterId o)

      Specified by:
        `compareTo` in interface `java.lang.Comparable<CounterId>`

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`

    - #### equals

          public boolean equals(java.lang.Object o)

      Overrides:
        `equals` in class `java.lang.Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `java.lang.Object`
