Constructor & Destructor Documentation

OBUnitCell (  ) 

public constructor

OBUnitCell ( const OBUnitCell src  ) 

~OBUnitCell (  )  [inline]


Member Function Documentation

virtual OBGenericData* Clone ( OBBase  )  const [inline, virtual]

Reimplemented from OBGenericData.

OBUnitCell & operator= ( const OBUnitCell src  ) 

void SetData ( const double  a,
const double  b,
const double  c,
const double  alpha,
const double  beta,
const double  gamma 
) [inline]

Sets the vectors and angles of the unitcell.

Parameters:
a The length a
b The length b
c The length c
alpha The angle alpha
beta The angle beta
gamma The angle gamma

void SetData ( const vector3  v1,
const vector3  v2,
const vector3  v3 
)

Sets the vectors, angles and lengths of the unitcell.

The angles and lengths of the unitcell will be calculated from the vectors v1, v2 and v3. Those vectors will as well be stored internally. Implements blue-obelisk:convertCartesianIntoNotionalCoordinates

Parameters:
v1 The x-vector
v2 The y-vector
v3 The z-vector

OBUnitCell::GetCellVectors

void SetOffset ( const vector3  v1  )  [inline]

Set the offset to the origin to v1.

void SetSpaceGroup ( const SpaceGroup sg  )  [inline]

Set the space group for this unit cell. Does not create an OBSymmetryData entry

void SetSpaceGroup ( const std::string  sg  )  [inline]

Set the space group symbol for this unit cell. Does not create an OBSymmetryData entry or attempt to convert between different symbol notations

void SetSpaceGroup ( const int  sg  )  [inline]

Set the space group for this unit cell. Each spacegroup-symbol has a numeric equivalent which is easier to use to convert between notations. Does not create an OBSymmetryData entry or attempt to convert between different symbol notations

void SetLatticeType ( const LatticeType  lt  )  [inline]
