`int`	`nextInt(Random random, int nearbySize)`

- Method Detail
  - nextInt
```
int nextInt(Random random,
            int nearbySize)
```
    Parameters:
    
    random - never null
    
    nearbySize - never negative. The number of available values to select from. Normally this is the size of the value range for a non-chained variable and the size of the value range (= size of the entity list) minus 1 for a chained variable.
    
    Returns:
    
    0 <= x < nearbySize
  - getOverallSizeMaximum
```
int getOverallSizeMaximum()
```
    Used to limit the RAM memory size of the nearby distance matrix.
    
    Returns:
    
    one more than the maximum number that nextInt(Random, int) can return, Integer.MAX_VALUE if there is none
