```
public AbstractPolygon()
```
- Method Detail
  - contains
```
public final boolean contains(HorizontalPosition pos)
```
    Specified by:
    
    contains in interface Domain<HorizontalPosition>
    
    Returns:
    
    true if the given position is contained within this domain.
  - contains
```
public boolean contains(double x,
                        double y)
```
    This default implementation constructs a Path2D consisting of the vertices of the polygon, and uses this to test for containment. Subclasses may be able to override with a more efficient method.
  - getBoundaryPath
```
protected Path2D getBoundaryPath()
```
  - getBoundingBox
```
public BoundingBox getBoundingBox()
```
    Specified by:
    
    getBoundingBox in interface Polygon
    
    Returns:
    
    The MBR of this Polygon
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
