Member Function Documentation

virtual Field* afl::Field_2::clone (   )  const [virtual]

Returns: a deep copy of this field Implements afl::Field.

virtual data_t afl::Field_2::divergence (  const Point &  x  )  const [virtual]

Returns: the approximated divergence at a point. Parameters: x  the point to evaluate the derivative at. Exceptions: ddf::IllegalOperationException  iff the field type is not a vector Implements afl::Field.

virtual Value afl::Field_2::get (  const Point &  p  )  const [virtual]

evaluates the field at a point Parameters: p  the point to evaluate the field at Returns: the interpolated value at x. Implements afl::Field.

virtual Point afl::Field_2::getBoundingBoxMax (   )  const [virtual]

Returns: the maximums corner of the bounding hyper-box around the field. This the corner with the maximal values on all axes of the point Exceptions: ddf::IllegalOperationException  if the field is describe analytically and no boundary is set. Implements afl::Field.

virtual Point afl::Field_2::getBoundingBoxMin (   )  const [virtual]

Returns: the minimums corner of the bounding hyper-box around the field. This the corner with the minimal values on all axes of the point Exceptions: ddf::IllegalOperationException  if the field is describe analytically and no boundary is set. Implements afl::Field.

virtual size_t afl::Field_2::getDimension (   )  const [inline, virtual]

Returns: the number of dimensions in the field. Note that this may be different to the number of dimensions of whatever is stored in the field. For example a 3D scalar field will return 3 and not 1. Implements afl::Field.

virtual Point afl::Field_2::gradient (  const Point &  x  )  const [virtual]

Returns: the approximated gradient at a point. Parameters: x  the point to evaluate the derivative at. Exceptions: ddf::IllegalOperationException  iff the field type is not scalar Todo: convert the return type to Vector Implements afl::Field.

virtual Value afl::Field_2::integral (  const Simplex &  s  )  const [virtual]

provides the integral of the field over a simplex. It is possible to take any integral over multiple simplexes. In the future there may be a function that uses BSP trees to take the integral over multiple simplices at ones at much better than linear rate. Parameters: s  the simplex to integrate over. The returned Value object has the same shape as the value of the field and each aspect of the value is integrated separately. Returns: the approximate integration of the field over a simplex. Exceptions: ddf::InvalidArgumentException  if the simplex has the wrong dimension for the field. Implements afl::Field.

virtual void afl::Field_2::interpolation (  interp_t  method  )  [virtual]

sets the interpolation method to use in the field Parameters: method  currently only valid value is I_LINEAR Exceptions: InvalidArgumentException  if a different argument is given Implements afl::Field.

virtual Derivative afl::Field_2::jacobian (  const Point &  x  )  const [virtual]

Returns: the approximated Jacobian at a point. Parameters: x  the point to evaluate the derivative at. Implements afl::Field.

virtual data_t afl::Field_2::laplacian (  const Point &  x  )  const [virtual]

Returns: the approximated Laplacian at a point. Parameters: x  the point to evaluate the derivative at. Exceptions: ddf::IllegalOperationException  iff the field type is not a scalar Implements afl::Field.

virtual void afl::Field_2::set (  const Point &  x, const Value &  value, const Derivative &  dvalue )  [virtual]

adds a new data point to the field. The interpolation has to guarantee that field would go through this point. If a point is exists in the field, this point would overwrite it. note that if the field is empty and this is the first set() call to it, then the field will store the field's derivative from now on. It doesn't mean that the derivative has to be used though. Parameters: x  the location of the new point value  the value of the property at point x dvalue  the partial derivative of the field at point x Exceptions: ddf::InvalidArgumentException  if the field doesn't store derivatives. Implements afl::Field.

virtual void afl::Field_2::set (  const Point &  x, const Value &  value )  [virtual]

adds a new data point to the field. The interpolation has to guarantee that field would go through this point. If a point is exists in the field, this point would overwrite it. Parameters: x  the location of the new point value  the value of the property at point x Exceptions: ddf::InvalidArgumentException  if the field stores derivatives. Implements afl::Field.
