MessageCondition

interface MessageCondition<T : Any>

Contract for mapping conditions to messages.

Message conditions can be combined (e.g. type + method-level conditions), matched to a specific Message, as well as compared to each other in the context of a Message to determine which one matches a request more closely.

Parameters

Functions

combine	`abstract fun combine(other: T): T` Define the rules for combining this condition with another. For example combining type- and method-level conditions.
compareTo	`abstract fun compareTo(other: T, message: Message<*>): Int` Compare this condition to another in the context of a specific message. It is assumed both instances have been obtained via `#getMatchingCondition(Message)` to ensure they have content relevant to current message only.
getMatchingCondition	`abstract fun getMatchingCondition(message: Message<*>): T` Check if this condition matches the given Message and returns a potentially new condition with content tailored to the current message. For example a condition with destination patterns might return a new condition with sorted, matching patterns only.
