Description

The list of methods to do SortedMap Usage are organized into topic(s).

Method

longcomputeByteSizeM(SortedMap byteSizeByName)
Computes total byte size. 
long totalByteSize = 0;
for (Long byteSize : byteSizeByName.values()) {
    totalByteSize += byteSize.longValue();
return totalByteSize;
ListcomputePathCauselessLms( List>> depCausesByNameList)
Removes the causes. 
final List<String> nameList = new ArrayList<String>();
final int size = depCausesByNameList.size();
for (int i = 0; i < size; i++) {
    final SortedMap<String, SortedSet<String>> depCausesByName = depCausesByNameList.get(i);
    if (depCausesByName.size() != 1) {
        throw new IllegalArgumentException("map size must be 1, but map is " + depCausesByName);
    final String name = depCausesByName.firstKey();
...
SortedMapfilterPrefix(SortedMap baseMap, String prefix)
filter Prefix 
if (prefix.length() > 0) {
    char nextLetter = (char) (prefix.charAt(prefix.length() - 1) + 1);
    String end = prefix.substring(0, prefix.length() - 1) + nextLetter;
    return baseMap.subMap(prefix, end);
return baseMap;
SortedMapfind(SortedMap map, String baseName)
find 
return map.subMap(baseName, baseName.concat("\uFFFF"));
TfirstElement(Collection c)
first Element 
if (c == null || c.size() == 0) {
    return null;
} else {
    return c.iterator().next();
TfirstElement(Collection c)
first Element 
if (isEmpty(c)) {
    return null;
return c.iterator().next();
StringgeneratePropertiesFilter(SortedMap propertiesMap)
Generate a Filter as a String given a Map of property/value pairs. 
if (propertiesMap.size() == 1) {
    return "(" + propertiesMap.firstKey() + "=" + propertiesMap.get(propertiesMap.firstKey()) + ")";
} else if (propertiesMap.size() > 1) {
    return "(&"
            + generatePropertiesFilter(
                    propertiesMap.subMap(propertiesMap.firstKey(), propertiesMap.firstKey() + "\0"))
            + generatePropertiesFilter(propertiesMap.tailMap(propertiesMap.firstKey() + "\0")) + ")";
return "";
ListgetAll(SortedMap map)
Given a sorted map with integer keys and entries of type T[] , this method returns a list of all entries of type T in the induced ordering. 
List<T> array = new ArrayList<T>();
for (int i : map.keySet()) {
    T[] entry = map.get(i);
    for (T t : entry) {
        array.add(t);
return array;
...
UgetObjectSortedMap(SortedMap map, T key)
get Object Sorted Map 
if (map == null) {
    return null;
return map.get(key);
booleanisCollectionClass(Class clazz)
is Collection Class 
return clazz == Collection.class || clazz == java.util.List.class || clazz == java.util.Set.class
        || clazz == java.util.Map.class || clazz == java.util.SortedSet.class 
        || clazz == java.util.SortedMap.class;
