Method Detail

get

List<V> get(int... indexes)

Loads elements by specified indexes

Parameters:

indexes - of elements

Returns:

list of elements

mapReduce

<KOut,VOut> RCollectionMapReduce<V,KOut,VOut> mapReduce()

Returns RMapReduce object associated with this map

Type Parameters:

KOut - output key

VOut - output value

Returns:

MapReduce instance

addAfter

int addAfter(V elementToFind,
             V element)

Add element after elementToFind

Parameters:

elementToFind - - object to find

element - - object to add

Returns:

new list size

addBefore

int addBefore(V elementToFind,
              V element)

Add element before elementToFind

Parameters:

elementToFind - - object to find

element - - object to add

Returns:

new list size

fastSet

void fastSet(int index,
             V element)

Set element at index. Works faster than List.set(int, Object) but doesn't return previous element.

Parameters:

index - - index of object

element - - object to set

subList

RList<V> subList(int fromIndex,
                 int toIndex)

Specified by:

subList in interface List<V>

readAll

List<V> readAll()

Read all elements at once

Returns:

list of values

trim

void trim(int fromIndex,
          int toIndex)

Trim list and remains elements only in specified range fromIndex, inclusive, and toIndex, inclusive.

Parameters:

fromIndex - - from index

toIndex - - to index

range

List<V> range(int toIndex)

Returns range of values from 0 index to toIndex. Indexes are zero based. -1 means the last element, -2 means penultimate and so on.

Parameters:

toIndex - - end index

Returns:

elements

range

List<V> range(int fromIndex,
              int toIndex)

Returns range of values from fromIndex to toIndex index including. Indexes are zero based. -1 means the last element, -2 means penultimate and so on.

Parameters:

fromIndex - - start index

toIndex - - end index

Returns:

elements

fastRemove

void fastRemove(int index)

Remove object by specified index

Parameters:

index - - index of object

remove

boolean remove(Object element,
               int count)

Removes up to count occurrences of element

Parameters:

element - - element to find

count - - amount occurrences

Returns:

true if at least one element removed; or false if element isn't found
