- - ### Method Detail

    - #### create

          static AmqpMessageBuilder create()

      Returns:
        a builder to create an `AmqpMessage`.

    - #### create

          static AmqpMessageBuilder create(AmqpMessage existing)

      Creates a builder to create a new `AmqpMessage` copying the metadata from the passed message.
      Parameters:
        `existing` - an existing message, must not be `null`.
      Returns:
        a builder to create an `AmqpMessage`.

    - #### create

          static AmqpMessageBuilder create(org.apache.qpid.proton.message.Message existing)

      Creates a builder to create a new `AmqpMessage` copying the metadata from the passed (Proton) message.
      Parameters:
        `existing` - an existing (Proton) message, must not be `null`.
      Returns:
        a builder to create an `AmqpMessage`.

    - #### isDurable

          boolean isDurable()

      Returns:
        whether or not the message is durable.
      See Also:
        AMQP specification

    - #### isFirstAcquirer

          boolean isFirstAcquirer()

      Returns:
        if `true`, then this message has not been acquired by any other link. If `false`, then this message MAY have previously been acquired by another link or links.
      See Also:
        AMQP specification

    - #### priority

          int priority()

      Returns:
        the relative message priority. Higher numbers indicate higher priority messages. Messages with higher priorities MAY be delivered before those with lower priorities.
      See Also:
        AMQP specification

    - #### deliveryCount

          int deliveryCount()

      Returns:
        the number of unsuccessful previous attempts to deliver this message. If this value is non-zero it can be taken as an indication that the delivery might be a duplicate. On first delivery, the value is zero. It is incremented upon an outcome being settled at the sender, according to rules defined for each outcome.
