Built-in Methods

Jactl provides a number of built-in methods for the standard types.

List Methods

List add(Object element)
List addAt(int index, Object element)
boolean allMatch(Function predicate=null)
boolean anyMatch(Function predicate=null)
Decimal avg()
List collect(Function mapper=null)
List collectEntries(Function mapper=null)
List each(Function action=null)
Iterator filter(Function predicate=null)
Iterator flatMap(Function mapper=null)
Iterator fmap(Function mapper=null)
Map groupBy(Function closure)
Iterator grouped(int size)
String join(String separator='')
Iterator limit(int count)
Iterator map(Function mapper=null)
Iterator mapWithIndex(Function mapper=null)
Iterator mapi(Function mapper=null)
Object max(Function closure=null)
Object min(Function closure=null)
boolean noneMatch(Function predicate=null)
Object reduce(Object initial, Function accumulator)
Object remove(int index)
List reverse()
int size()
Iterator skip(int count)
List sort(Function comparator=null)
List subList(int start)
List subList(int start, int end)
Object sum()
Iterator transpose()
Iterator unique()
Iterator windowSliding(int size)

Map Methods

Maps can be treated as Lists so all List methods can also be applied to Maps. In addition, these methods are specific to Maps:

Object get(Object key)
Map put(Object key, Object value)
Map putAll(Map values)
Object remove(String key)

String Methods

Strings can be treated as a list of characters so List methods can also be applied to String objects. Strings also have these methods:

long asNum(int base=10)
Iterator lines()
int size()
Iterator split(String regex=null, String modifiers='')
String substring(int start)
String substring(int start, int end)
String toLowerCase()
String toLowerCase(int count)
String toUpperCase()
String toUpperCase(int count)

Number Methods

Number methods apply to all numeric types (int, long, byte, double, and BigDecimal).

Number abs()
String asChar()
Number pow(Number power)
Number sqr()
Number sqrt()
Number toBase(int base)
