MessageCondition

Contract for mapping conditions to messages.

<p>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.

@author Rossen Stoyanchev @since 4.0 @param (T) the kind of condition that this condition can be combined with or compared to

interface MessageCondition (

) {

T combine(T other);

T getMatchingCondition(MessageBase message);

int compareTo(T other, MessageBase message);

}

Functions

combine T combine(T other): Define the rules for combining this condition with another. For example combining type- and method-level conditions. @param other the condition to combine with @return the resulting message condition
compareTo int compareTo(T other, MessageBase message): Compare this condition to another in the context of a specific message. It is assumed both instances have been obtained via {@link #getMatchingCondition(Message)} to ensure they have content relevant to current message only.
getMatchingCondition T getMatchingCondition(MessageBase message): 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. @return a condition instance in case of a match; or {@code null} if there is no match.
