Description
Fix the bug related to duplicate paths in
PathPatternTreeappendPathPattern,PathPatternTreeshould judge the inclusion relationship between new path and existed paths. The included path should not be stored. The added Pattern may not be a fullPath, soPathPatternTreeusedmatchFullPath()incorrectly. This pr implements an algorithm to judge the partialPath inclusion relationship to replacematchFullPath().getAllDevicePatterns,PathPatternTreeshould de-duplicate the result set.
