Interface IMessageProperties
interface IMessageProperties
Extends com.amazon.apmf.IStandard
Message Properties control how the message is handled by the OS. See
IMessagePropertiesBuilder for available options.
This interface is intentionally an opaque token. Instances are created by
IMessagePropertiesBuilder and consumed by IMessageBuilder. There are
no client-readable getters because property values are write-once via
the builder and are interpreted by the system. A future version may
extend this type with introspection methods if a use case emerges.
