public class PropertyNamesMatcher<T> extends Object
A matcher of configuration names.

Names without wildcards are stored in a HashMap for exact lookup. Names containing * or ** are stored in a trie of PropertyNamesMatcher.Node instances, where each node represents a segment separated by .. Single * segments are stored in the PropertyNamesMatcher.Node.wildcard, and ** sets the PropertyNamesMatcher.Node.greedy flag to match any number of remaining segments.

Lookups (matches(java.lang.String) and get(java.lang.String)) first check the exact-match map, then traverse the wildcard trie, trying named children before falling back to wildcard nodes at each level.
