Method Detail
- getGreyThreshold
```
public static final int getGreyThreshold()
```
  Returns the default Grey value.
  
  Returns:
  
  The grey value threshold
- getDistanceThreshold
```
public static final double getDistanceThreshold()
```
  Returns the default distance threshold.
  
  Returns:
  
  The distance threshold
- step
```
public final boolean step(int granularity)
```
  Description copied from interface: StagedAlgorithm
  
  Executes a defineable portion of the algorithm.
  
  Specified by:
  
  step in interface StagedAlgorithm
  
  Parameters:
  
  granularity - Number of steps to be executed before retuning (until further execution by a consecutive call)
  
  Returns:
  
  True if this algorithm can be continued by a further call, false otherwise.
