Interface WArrayList<T>

Type Parameters:

T - Element type

All Superinterfaces:

WCollection<T>, org.apache.hadoop.io.Writable

All Known Implementing Classes:

public interface WArrayList<T>
extends WCollection<T>

Array list over mutable elements, which are probably internally stored differently/efficiently, and are accessed through methods providing "return" value.

Method Summary

Modifier and Type	Method and Description
void	fillW(int from, int to, T value) Sets given range of elements to a specified value.
void	getIntoW(int index, T to) Get element at given index in the array, storing it into 'to' argument
void	popIntoW(T to) Pop value from the end of the array, storing it into 'to' argument
void	setW(int index, T value) Set element at given index in the array
void	size(int newSize) Sets the size of this
void	sort() Sort the array in ascending order

Method Detail

size

void size(int newSize)

Sets the size of this

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Parameters:

newSize - the new size.

trim

void trim()

Trims this array list so that the capacity is equal to the size.

popIntoW

void popIntoW(T to)

Pop value from the end of the array, storing it into 'to' argument

Parameters:

to - Object to store value into

getIntoW

void getIntoW(int index,
              T to)

Get element at given index in the array, storing it into 'to' argument

Parameters:

index - Index

to - Object to store value into

setW

void setW(int index,
          T value)

Set element at given index in the array

Parameters:

index - Index

value - Value

fillW

void fillW(int from,
           int to,
           T value)

Sets given range of elements to a specified value.

Parameters:

from - From index (inclusive)

to - To index (exclusive)

value - Value

sort

void sort()

Sort the array in ascending order
