Hierarchical token matcher for Strings
This code was inspired by the following concern : A message broker needs a way to find all subscribers listening to a destination (including hierarchical subscriptions). A client should be able to subscribe to multiple topics relevant to a given context with a single subscription using this pattern. e.g. To capture all news for all categories for today - can subscribe like "news.+.today".
This sample provides an efficient, abstract way to manage such subscriptions. (inspired by moquette subscription logic) Hierarchy definitions : dest.* - captures all immediate child elements to "dest". dest.# - captures all immediate child elements + parent (e:g: "dest" and "dest.news") dest.news - captures exactly "dest.news" destination dest.+.news - captures "dest.sports.news" and "dest.crisis.news" Still working on optimizations, so your comments are much valued :) https://github.com/hastef88/wso2.tryouts/tree/master/token_matcher
