Modifier and Type	Method and Description
public DestinationPatternsMessageCondition	combine(DestinationPatternsMessageCondition the condition to combine with other) Implements org.springframework.messaging.handler.MessageCondition.combine. Returns a new instance with URL patterns from the current instance ("this") and the "other" instance as follows: If there are patterns in both instances, combine the patterns in "this" with the patterns in "other" using `org.springframework.util.PathMatcher#combine(String, String)`. If only one instance has patterns, use them. If neither instance has patterns, use an empty String (i.e. "").

Check if any of the patterns match the given Message destination and return an instance that is guaranteed to contain matching patterns, sorted via `org.springframework.util.PathMatcher#getPatternComparator(String)`.

compareTo	back to summary
public int compareTo(DestinationPatternsMessageCondition other, Message<?> message) Implements org.springframework.messaging.handler.MessageCondition.compareTo. Compare the two conditions based on the destination patterns they contain. Patterns are compared one at a time, from top to bottom via `org.springframework.util.PathMatcher#getPatternComparator(String)`. If all compared patterns match equally, but one instance has more patterns, it is considered a closer match. It is assumed that both instances have been obtained via `getMatchingCondition(Message)` to ensure they contain only patterns that match the request and are sorted with the best matches on top.
