virtual bool MgGeometry::Overlaps | ( | MgGeometry * | other | ) | `[virtual]`
Given 2 geometries a and b, a.Overlaps(b) is true if and only if the dimension of the interior of a equals the dimension of the interior of b equals the dimension of the intersection of the interior of a and the interior of b and the intersection of a and b is neither a nor b. Remarks: A Point cannot overlap a Point, and a MultiPoint cannot overlap a Point but a MultiPoint can overlap a MultiPoint. ## Illustration c and d are MultiPoint geometries. .NET Syntax
`virtual bool Overlaps(MgGeometry other);`
Java Syntax
`virtual boolean Overlaps(MgGeometry other);`
PHP Syntax
`virtual bool Overlaps(MgGeometry other);`
  Parameters:
  | other | (MgGeometry) The MgGeometry to test against this one.
Returns: True if this geometry spatially overlaps the other geometry, false otherwise.
