DistributionSchedule.WriteSet (Apache BookKeeper :: Parent 4.18.0-SNAPSHOT API)

Enclosing interface:

DistributionSchedule
```
public static interface DistributionSchedule.WriteSet
```
A write set represents the set of bookies to which a request will be written. The set consists of a list of indices which can be used to lookup the bookie in the ensemble.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addMissingIndices(int maxIndex)`	If we want a write set to cover all bookies in an ensemble of size X, then all of the index from 0..X must exist in the write set.
`boolean`	`contains(int i)`	Whether the set contains the given index.
`DistributionSchedule.WriteSet`	`copy()`	Make a deep copy of this write set.
`int`	`get(int i)`	Get the index at index i.
`int`	`indexOf(int index)`	Index of a specified bookie index.
`void`	`moveAndShift(int from, int to)`	Move an index from one position to another, shifting the other indices accordingly.
`void`	`recycle()`	Recycle write set object when not in use.
`int`	`set(int i, int index)`	Set the index at index i.
`int`	`size()`	The number of indexes in the write set.
`void`	`sort()`	Sort the indices.

- Method Detail
  - size
```
int size()
```
    The number of indexes in the write set.
  - contains
```
boolean contains(int i)
```
    Whether the set contains the given index.
  - get
```
int get(int i)
```
    Get the index at index i.
  - set
```
int set(int i,
        int index)
```
    Set the index at index i.
    
    Returns:
    
    the previous value at that index.
  - sort
```
void sort()
```
    Sort the indices.
  - indexOf
```
int indexOf(int index)
```
    Index of a specified bookie index. -1 if not found.
  - addMissingIndices
```
void addMissingIndices(int maxIndex)
```
    If we want a write set to cover all bookies in an ensemble of size X, then all of the index from 0..X must exist in the write set. This method appends those which are missing to the end of the write set.
  - moveAndShift
```
void moveAndShift(int from,
                  int to)
```
    Move an index from one position to another, shifting the other indices accordingly.
  - recycle
```
void recycle()
```
    Recycle write set object when not in use.
  - copy
```
DistributionSchedule.WriteSet copy()
```
    Make a deep copy of this write set.
