    • getDeclaringAdmins

      Collection<?> getDeclaringAdmins()

      Returns:
      the collection.

    • setAdminsThatShouldDeclare

      void setAdminsThatShouldDeclare(@Nullable Object... adminArgs)
      The AmqpAdmins that should declare this object; default is all admins.

      A null argument, or an array/varArg with a single null argument, clears the collection (setAdminsThatShouldDeclare((AmqpAdmin) null) or setAdminsThatShouldDeclare((AmqpAdmin[]) null)). Clearing the collection resets the behavior such that all admins will declare the object.
      Parameters:
      adminArgs - The admins.

    • addArgument

      default void addArgument(String name, Object value)
      Add an argument to the declarable.
      Parameters:
      name - the argument name.
      value - the argument value.
      Since:
      2.2.2

    • removeArgument

      @Nullable default Object removeArgument(String name)
      Remove an argument from the declarable.
      Parameters:
      name - the argument name.
      Returns:
      the argument value or null if not present.
