        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,

      • verifyOfferedCapabilities

        public static boolean verifyOfferedCapabilities​(org.apache.qpid.proton.engine.Link link)
        Verifies that the desired capabilities that were sent to the remote were indeed offered in return. If the remote has not offered a capability that was desired then the initiating resource should determine if the offered set is still acceptable or it should close the link and report the reason.

        The remote could have offered more capabilities than the requested desired capabilities, this method does not validate that or consider that a failure.

        Parameters:
        link - The link in question (Sender or Receiver).
        Returns:
        true if the remote offered all of the capabilities that were desired.

      • verifyOfferedCapabilities

        public static boolean verifyOfferedCapabilities​(org.apache.qpid.proton.engine.Link link,
                                                org.apache.qpid.proton.amqp.Symbol... capabilities)
        Verifies that the given set of desired capabilities (which should be the full set of desired capabilities configured on the link or a subset of those values) are indeed offered in return. If the remote has not offered a capability that was desired then the initiating resource should determine if the offered set is still acceptable or it should close the link and report the reason.

        The remote could have offered more capabilities than the requested desired capabilities, this method does not validate that or consider that a failure.

        Parameters:
        link - The link in question (Sender or Receiver).
        capabilities - The capabilities that are required being checked for.
        Returns:
        true if the remote offered all of the capabilities that were desired.

      • verifyDesiredCapability

        public static boolean verifyDesiredCapability​(org.apache.qpid.proton.engine.Link link,
                                              org.apache.qpid.proton.amqp.Symbol desiredCapability)
        Verifies that the given remote desired capability is present in the remote link details.

        The remote could have desired more capabilities than the one given, this method does not validate that or consider that a failure.

        Parameters:
        link - The link in question (Sender or Receiver).
        desiredCapability - The non-null capability that is being checked as being desired.
        Returns:
        true if the remote desired all of the capabilities that were given.
