### Question:
OwnLocalResources { public Pair<String,Path> splitTagAndBasename(Path path){ String name = path.getName(); Path parent = path.getParent(); if(name.startsWith(LR_PREFIX) == false){ return null; } name = name.substring(LR_PREFIX.length()); int underscore = name.indexOf(LR_TAG_DELIM); if(underscore == -1){ return null; } String tag = name.substring(0, underscore); String basename = name.substring(underscore + 1); if(LR_ALL_TAGS.contains(tag) == false){ return null; } return new Pair<>(tag, new Path(parent, basename)); } OwnLocalResources(String thisNodeTag);  OwnLocalResources(); static Set<String> getLocalResourcesAllTags(); static String getThisLocalResourceTag(); Pair<String,Path> splitTagAndBasename(Path path); Map<Path,List<String>> filterLocalResources(Map<Path,List<String>> originLocalResources); static final String LR_PREFIX; static final String LR_TAG_CENTOS6; static final String LR_TAG_CENTOS7; static final String LR_TAG_MACOS10; static final String LR_TAG_DELIM; }### Answer:
