All Superinterfaces:

Filter, it.unimi.dsi.fastutil.ints.IntIterable, Iterable<Integer>

All Known Implementing Classes:

BitmapBackedSelection
```
public interface Selection
extends it.unimi.dsi.fastutil.ints.IntIterable, Filter
```
A selection maintains an ordered set of ints that can be used to eval rows from a table or column

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`Selection`	`add(int... ints)` Adds the given integers to the Selection if it is not already present, and does nothing otherwise
`Selection`	`addRange(int start, int end)` Adds to the current bitmap all integers in [rangeStart,rangeEnd)
`Selection`	`and(Selection otherSelection)` Returns the intersection of the receiver and `otherSelection`, after updating the receiver
`Selection`	`andNot(Selection otherSelection)` Implements the set difference operation between the receiver and `otherSelection`, after updating the receiver
`default Selection`	`apply(Column columnBeingFiltered)` Returns a selection created by applying this filter (and any optional params added in extending classes) to the given column
`default Selection`	`apply(Table relation)`
`Selection`	`clear()`
`boolean`	`contains(int i)`
`Selection`	`flip(int rangeStart, int rangeEnd)` Returns a selection with the bits from this selection flipped over the given range
`static int[]`	`generateUniformBitmap(int N, int Max)` Returns an randomly generated array of ints of size N where Max is the largest possible value
`int`	`get(int i)` Returns the value of the ith element.
`boolean`	`isEmpty()`
`Selection`	`or(Selection otherSelection)` Returns the union of the receiver and `otherSelection`, after updating the receiver
`Selection`	`removeRange(long start, long end)`
`static Selection`	`selectNRowsAtRandom(int n, int max)`
`int`	`size()`
`int[]`	`toArray()`
`org.roaringbitmap.RoaringBitmap`	`toBitmapInternal()` Returns a bitmap that represents the state of this selection
`static Selection`	`with(int... rows)`
`static Selection`	`withoutRange(int totalRangeStart, int totalRangeEnd, int excludedRangeStart, int excludedRangeEnd)`
`static Selection`	`withRange(int start, int end)`

- Method Detail
  - with
```
static Selection with(int... rows)
```
  - withRange
```
static Selection withRange(int start,
                           int end)
```
  - withoutRange
```
static Selection withoutRange(int totalRangeStart,
                              int totalRangeEnd,
                              int excludedRangeStart,
                              int excludedRangeEnd)
```
  - toArray
```
int[] toArray()
```
  - toBitmapInternal
```
org.roaringbitmap.RoaringBitmap toBitmapInternal()
```
    Returns a bitmap that represents the state of this selection
  - add
```
Selection add(int... ints)
```
    Adds the given integers to the Selection if it is not already present, and does nothing otherwise
  - addRange
```
Selection addRange(int start,
                   int end)
```
    Adds to the current bitmap all integers in [rangeStart,rangeEnd)
    
    Parameters:
    
    start - inclusive beginning of range
    
    end - exclusive ending of range
  - removeRange
```
Selection removeRange(long start,
                      long end)
```
  - size
```
int size()
```
  - and
```
Selection and(Selection otherSelection)
```
    Returns the intersection of the receiver and otherSelection, after updating the receiver
  - or
```
Selection or(Selection otherSelection)
```
    Returns the union of the receiver and otherSelection, after updating the receiver
  - andNot
```
Selection andNot(Selection otherSelection)
```
    Implements the set difference operation between the receiver and otherSelection, after updating the receiver
  - isEmpty
```
boolean isEmpty()
```
  - clear
```
Selection clear()
```
  - contains
```
boolean contains(int i)
```
  - get
```
int get(int i)
```
    Returns the value of the ith element. For example, if there are three ints {4, 32, 71} in the selection, get(0) returns 4, get(1) returns 32, and get(2) returns 71 It can be useful if you need to iterate over the data, although there is also an iterator
  - flip
```
Selection flip(int rangeStart,
               int rangeEnd)
```
    Returns a selection with the bits from this selection flipped over the given range
  - apply
```
default Selection apply(Table relation)
```
    Specified by:
    
    apply in interface Filter
  - apply
```
default Selection apply(Column columnBeingFiltered)
```
    Description copied from interface: Filter
    
    Returns a selection created by applying this filter (and any optional params added in extending classes) to the given column
    
    Specified by:
    
    apply in interface Filter
    
    Returns:
  - generateUniformBitmap
```
static int[] generateUniformBitmap(int N,
                                   int Max)
```
    Returns an randomly generated array of ints of size N where Max is the largest possible value
  - selectNRowsAtRandom
```
static Selection selectNRowsAtRandom(int n,
                                     int max)
```
