  • Field Details

    • tagValue

      protected final long tagValue

  • Constructor Details

    • ProtonNumericDeliveryTag

      public ProtonNumericDeliveryTag(long tagValue)

  • Method Details

    • tagLength

      public int tagLength()
      Specified by:
      tagLength in interface DeliveryTag
      Returns:
      the total number of bytes needed to represent the given tag.

    • tagBytes

      public byte[] tagBytes()
      Description copied from interface: DeliveryTag
      Returns a view of this DeliveryTag object as a byte array. The returned array may be the actual underlying tag bytes or a synthetic view based on the value used to generate the tag. It is advised not to modify the returned value and copy if such modification are necessary to the caller.
      Specified by:
      tagBytes in interface DeliveryTag
      Returns:
      the underlying tag bytes as a byte array that may or may no be a singleton instance..

    • tagBuffer

      public ProtonBuffer tagBuffer()
      Description copied from interface: DeliveryTag
      Returns a view of this DeliveryTag object as a ProtonBuffer. The returned array may be the actual underlying tag bytes or a synthetic view based on the value used to generate the tag. It is advised not to modify the returned value and copy if such modification are necessary to the caller.
      Specified by:
      tagBuffer in interface DeliveryTag
      Returns:
      the ProtonBuffer view of the tag bytes.

    • copy

      public DeliveryTag copy()
      Description copied from interface: DeliveryTag
      Create a copy of this delivery tag, the copy should account for any underlying pooling of tags that the tag source's implementation is using.
      Specified by:
      copy in interface DeliveryTag
      Returns:
      a copy of the underlying bytes that compose this delivery tag.

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • writeTo

      public void writeTo(ProtonBuffer buffer)
      Description copied from interface: DeliveryTag
      Writes the tag as a sequence of bytes into the given buffer in the manner most efficient for the underlying DeliveryTag implementation.
      Specified by:
      writeTo in interface DeliveryTag
      Parameters:
      buffer - The target buffer where the tag bytes are to be written.
