All Known Implementing Classes:

ArrayPositionLinks, SortedPositionLinks
```
public interface PositionLinks
```
This class is responsible for iterating over build rows, which have same values in hash columns as given probe row (but according to filterFunction can have non matching values on some other column).

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`long`	`getSizeInBytes()`

`int`	`start(int position, int probePosition, Page allProbeChannelsPage)`	Initialize iteration over position links.

- Method Detail
  - getSizeInBytes
```
long getSizeInBytes()
```
  - start
```
int start(int position,
          int probePosition,
          Page allProbeChannelsPage)
```
    Initialize iteration over position links. Returns first potentially eligible join position starting from (and including) position argument.
    When there are no more position -1 is returned
  - next
```
int next(int position,
         int probePosition,
         Page allProbeChannelsPage)
```
    Iterate over position links. When there are no more position -1 is returned.
