code: public function containsGeometry(GeometryInterface $geometry): bool

docs: Determine if given geometry is contained inside the polygon. This is
  assumed to be true, if each point of the geometry is inside the polygon.
  
  Edge cases:
  
  - it's not detected when a line between two points is outside the polygon
  - @see contains() for more restrictions
  
  @param GeometryInterface $geometry
  
  @return boolean
