XYSearcher (hunt snapshot API)

java.lang.Object
- com.treasure.hunt.strategy.searcher.impl.XYSearcher

All Implemented Interfaces:

Searcher<AngleHint>
```
public class XYSearcher
extends java.lang.Object
implements Searcher<AngleHint>
```
This type of Searcher holds the numbers maxX, maxY, minX, minY, and updates these.
This Hider works only for AngleHint with an angle ≤ {@link Math#PI}/2. Thus, this Searcher always gets one or two directions, in which the treasure lies for sure.
If the searcher knows only a minimum X, but no maximum X (or knows only a maximum X, but no minimum X), he will go in the correct X-direction and double its moving-distance each time.
Otherwise, if the searcher knows both a minimum X and a maximum X, he will go to the middle of these interval.
The same holds for the Y coordinates.

  - init
```
public void init(org.locationtech.jts.geom.Point searcherStartPosition)
```
    Specified by:
    
    init in interface Searcher<AngleHint>
    
    Parameters:
    
    searcherStartPosition - the Searcher starting position, he will initialized on.
  - move
```
public SearchPath move()
```
    Description copied from interface: Searcher
    
    Use this to perform a initial move, without a hint given. This is for the case, the searcher starts. (as he does normally)
    
    Specified by:
    
    move in interface Searcher<AngleHint>
    
    Returns:
    
    SearchPath, containing only the starting position.
  - move
```
public SearchPath move(AngleHint angleHint)
```
    If the searcher knows only a minimum X, but no maximum X (or knows only a maximum X, but no minimum X), he will go in the correct X-direction and double its moving-distance each time.
    Otherwise, if the searcher knows both a minimum X and a maximum X, he will go to the middle of these interval.
    The same holds for the Y coordinates.
    
    Specified by:
    
    move in interface Searcher<AngleHint>
    
    Parameters:
    
    angleHint - the hint, the Hider gave last.
    
    Returns:
    
    SearchPath the SearchPath, this searcher chose.
