示例1: findMatchingValues
import java.util.NavigableMap; //導入方法依賴的package包/類
private void findMatchingValues(NavigableMap<Endpoint, Integer> map, Endpoint endpoint, List<UUID> result) {
// Mark this endpoint as a marker, because it is used to do a tailMap traversal to query matching edges
endpoint.setMarker();
// Find the first key
Endpoint floorKey = map.floorKey(endpoint);
Map<Endpoint, Integer> view;
if (floorKey == null) {
// This means that the element being searched is the minimum
view = map;
} else {
view = map.tailMap(floorKey);
}
boolean isFirst = true;

Endpoint key = entry.getKey();
if (endpoint.isMatch(key)) {
// Matching entry, must be added to result
result.add(key.getEdgeId());
} else {
// Done with the search -- the tree map is sorted
if (isFirst) {
// continue
} else {
break;
}
}
isFirst = false;
}
}
示例2: removeMatchingKeys
import java.util.NavigableMap; //導入方法依賴的package包/類
