Description

The list of methods to do String Split are organized into topic(s).

Method

ListsplitForIndexMatching(String string)
Split so that we can create multiple WildcardQuery. 
int len = string.length();
if (len == 0) {
    return new ArrayList<>(0);
ArrayList<String> ret = new ArrayList<String>();
int last = 0;
char c = 0;
for (int i = 0; i < len; i++) {
...
ListsplitGenericIfNeeded(String name)
split Generic If Needed 
List<String> result = new ArrayList<>();
if (name.contains("<")) {
    result.add(name.substring(0, name.indexOf("<")).trim());
    for (String item : Arrays.asList(name.substring(name.indexOf("<") + 1, name.indexOf(">")).split(","))) {
        result.add(item.trim());
} else {
    result.add(name);
...
IteratorsplitHelperName(String name)
This implementation is quite naive and should be possibly rewritten. 
boolean literal = false;
boolean whitespace = false;
List<String> parts = new ArrayList<String>();
StringBuilder buffer = new StringBuilder();
for (int i = 0; i < name.length(); i++) {
    if (name.charAt(i) == ' ') {
        if (!whitespace) {
            if (!literal) {
...
ListsplitHistory(String history)
Split history string to history path using HISTORY_SEP as the separator 
List<String> historyPath;
if (history.indexOf(HISTORY_SEP) == -1) {
    historyPath = Arrays.asList(history);
} else {
    historyPath = Arrays.asList(history.split(HISTORY_SEP_REGEX));
return historyPath;
ListsplitHTMLTags(final String string)
Splits the given string on spaces and certain embedded HTML tags. 
if (!string.contains("<")) {
    return splitOnSpace(string);
String tempString = string;
tempString = replace(tempString, "<br>", " <br> ");
tempString = replace(tempString, "<ol>", " <ol> ");
tempString = replace(tempString, "</ol>", " </ol> ");
tempString = replace(tempString, "<ul>", " <ul> ");
...
MapsplitIdKeyConfig(String config)
split a keyid string into a map 
HashMap<String, String> result = new HashMap<>();
String[] split = config.split(",");
for (String s : split) {
    if (s != null && !s.isEmpty()) {
        if (s.contains("@")) {
            String[] idSplit = s.split("@");
            if (idSplit.length > 1) {
                result.put(idSplit[1], idSplit[0]);
...
ListsplitInitialItems(final String text)
Split initial value text into items. 
if (text == null || text.isEmpty())
    return null;
final List<String> items = new ArrayList<>();
int pos = 0;
while (pos < text.length()) {
    final char c = text.charAt(pos);
    if (c == ' ' || c == '\t')
        ++pos;
...
ArrayListsplitInput(String cliInput)
Splits the input of comma separated command line input and returns the results as an arraylist. 
ArrayList<String> results = new ArrayList<String>();
if (cliInput == null || cliInput.trim().length() == 0) {
    return results;
for (String tempInput : cliInput.split(SEPARATOR)) {
    results.add(tempInput.trim());
return results;
...
int[]splitIntArray(final String iInput)
split Int Array 
final List<String> items = split(iInput, RECORD_SEPARATOR);
final int[] values = new int[items.size()];
for (int i = 0; i < items.size(); ++i) {
    values[i] = Integer.parseInt(items.get(i).trim());
return values;
ListsplitIntegerFromString(String str)
split Integer From String 
List<Integer> integerList = null;
if (null == str) {
    return integerList;
integerList = new ArrayList<Integer>();
String numDict = "0123456789";
char[] strChars = str.toCharArray();
StringBuffer sbuffer = new StringBuffer();
