    • contains

      public static boolean contains(org.apache.qpid.proton.amqp.Symbol[] symbols, org.apache.qpid.proton.amqp.Symbol key)
      Search for a given Symbol in a given array of Symbol object.
      Parameters:
      symbols - the set of Symbols to search.
      key - the value to try and find in the Symbol array.
      Returns:
      true if the key is found in the given Symbol array.

    • findFilter

      public static Map.Entry<org.apache.qpid.proton.amqp.Symbol,org.apache.qpid.proton.amqp.DescribedType> findFilter(Map<org.apache.qpid.proton.amqp.Symbol,Object> filters, Object[] filterIds)
      Search for a particular filter using a set of known indentification values in the Map of filters.
      Parameters:
      filters - The filters map that should be searched.
      filterIds - The aliases for the target filter to be located.
      Returns:
      the filter if found in the mapping or null if not found.

    • toBuffer

      public static org.fusesource.hawtbuf.Buffer toBuffer(ByteBuffer data)
      Conversion from Java ByteBuffer to a HawtBuf buffer.
      Parameters:
      data - the ByteBuffer instance to convert.
      Returns:
      a new HawtBuf buffer converted from the given ByteBuffer.

    • toBytes

      public static byte[] toBytes(long value)
      Given a long value, convert it to a byte array for marshalling.
      Parameters:
      value - the value to convert.
      Returns:
      a new byte array that holds the big endian value of the long.

    • toLong

      public static long toLong(org.apache.qpid.proton.amqp.Binary value)
      Converts a Binary value to a long assuming that the contained value is stored in Big Endian encoding.
      Parameters:
      value - the Binary object whose payload is converted to a long.
      Returns:
      a long value constructed from the bytes of the Binary instance.

    • createDestination

      public static org.apache.activemq.command.ActiveMQDestination createDestination(Object endpoint) throws AmqpProtocolException
      Given an AMQP endpoint, deduce the appropriate ActiveMQDestination type and create a new instance. By default if the endpoint address does not carry the standard prefix value then we default to a Queue type destination. If the endpoint is null or is an AMQP Coordinator type endpoint this method returns null to indicate no destination can be mapped.
      Parameters:
      endpoint - the AMQP endpoint to construct an ActiveMQDestination from.
      Returns:
      a new ActiveMQDestination that best matches the address of the given endpoint
      Throws:
      AmqpProtocolException - if an error occurs while deducing the destination type.

    • getDestinationTypeSymbol

      public static org.apache.qpid.proton.amqp.Symbol getDestinationTypeSymbol(org.apache.activemq.command.ActiveMQDestination destination)
      Given an ActiveMQDestination return the proper Capability value for the concrete destination type.
      Parameters:
      destination - The ActiveMQDestination whose capability is being requested.
      Returns:
      a Symbol that matches the defined Capability value for the ActiveMQDestiantion.
