Function Documentation

◆ append()

std::shared_ptr< FrameSet > ast::append ( FrameSet const &  first,
FrameSet const &  second 
)

Construct a FrameSet that performs two transformations in series.

When used as a Mapping, the FrameSet shall apply first, followed by second. Its inverse shall apply the inverse of second, followed by the inverse of first. The concatenation is only valid if first.getCurrent() and second.getBase() have the same number of axes.

The new FrameSet shall contain all Frames and Mappings from first, followed by all Frames and Mappings from second, preserving their original order. The current frame of first shall be connected to the base frame of second by a UnitMap. The new set's base frame shall be the base frame of first, and its current frame shall be the current frame of second.

The FrameSet shall be independent of the input arguments, so changes to the original FrameSets (in particular, reassignments of their base or current frames) shall not affect it.

Parameters
first,secondthe FrameSets to concatenate.
Returns
a pointer to a combined FrameSet as described above

Example: if first has 3 frames and secondhas 4, then the result shall contain 7 frames, of which frames 1-3 are the same as frames 1-3 of first, in order, and frames 4-7 are the same as frames 1-4 of second, in order.

Definition at line 33 of file functional.cc.

33  {
34  std::shared_ptr<FrameSet> const merged = first.copy();
35  std::shared_ptr<FrameSet> const newFrames = second.copy();
36 
37  newFrames->setCurrent(FrameSet::BASE);
38  int const joinNAxes = first.getFrame(FrameSet::CURRENT)->getNAxes();
39  merged->addFrame(FrameSet::CURRENT, UnitMap(joinNAxes), *newFrames);
40 
41  // All frame numbers from `second` have been offset in `merged` by number of frames in `first`
42  int const mergedCurrent = first.getNFrame() + second.getCurrent();
43  merged->setCurrent(mergedCurrent);
44 
45  return merged;
46 }

◆ arrayFromVector() [1/2]

Array2D ast::arrayFromVector ( std::vector< double > &  vec,
int  nAxes 
)

Reshape a vector as a 2-dimensional array that shares the same memory.

To convert a vector of coefficients to an array of coefficients for PolyMap or ChebyMap, call this with nAxes = nPoints / width, where width is the number of elements in each coefficient: width = nOut + 2 for forward coefficients, nIn + 2 for inverse coefficients.

Parameters
[in]vecVector of points, with all values for one axis first, then the next axes, and so on, e.g. x1, x2, ...xnPt, y1, y2, ...ynNpt
[in]nAxesNumber of axes per point
Returns
2-dimensional array with dimensions (nPts, nAxes)
Exceptions
std::runtime_errorif vec length is not a multiple of nAxes
Warning
You must hold onto the original vector until you are done with the returned array, else the array will be corrupted. (However, the Python version returns a copy, to avoid memory issues.)

Definition at line 69 of file base.cc.

69  {
70  int nPoints = vec.size() / nAxes;
71  if (nPoints * nAxes != vec.size()) {
73  os << "vec length = " << vec.size() << " not a multiple of nAxes = " << nAxes;
74  throw std::runtime_error(os.str());
75  }
76  Array2D::Index shape = ndarray::makeVector(nAxes, nPoints);
77  Array2D::Index strides = ndarray::makeVector(nPoints, 1);
78  return external(vec.data(), shape, strides);
79 }

◆ arrayFromVector() [2/2]

ConstArray2D ast::arrayFromVector ( std::vector< double > const &  vec,
int  nAxes 
)

Reshape a vector as a 2-dimensional array that shares the same memory.

To convert a vector of coefficients to an array of coefficients for PolyMap or ChebyMap, call this with nAxes = nPoints / width, where width is the number of elements in each coefficient: width = nOut + 2 for forward coefficients, nIn + 2 for inverse coefficients.

Parameters
[in]vecVector of points, with all values for one axis first, then the next axes, and so on, e.g. x1, x2, ...xnPt, y1, y2, ...ynNpt
[in]nAxesNumber of axes per point
Returns
2-dimensional array with dimensions (nPts, nAxes)
Exceptions
std::runtime_errorif vec length is not a multiple of nAxes
Warning
You must hold onto the original vector until you are done with the returned array, else the array will be corrupted. (However, the Python version returns a copy, to avoid memory issues.)

Definition at line 65 of file base.cc.

65  {
66  return static_cast<ConstArray2D>(arrayFromVector(const_cast<std::vector<double> &>(vec), nAxes));
67 }

◆ assertOK()

void ast::assertOK ( AstObject *  rawPtr1 = nullptr,
AstObject *  rawPtr2 = nullptr 
)

Throw std::runtime_error if AST's state is bad.

Parameters
rawPtr1An AST object to free if status is bad
rawPtr2An AST object to free if status is bad
Note
on the first call an error handler is registered that saves error messages to a buffer.

Definition at line 49 of file base.cc.

49  {
50  // Construct ErrorHandler once, the first time this function is called.
51  // This is done to initialize `errorMsgStream` and register `reportError` as the AST error handler.
52  // See https://isocpp.org/wiki/faq/ctors#static-init-order-on-first-use
53  static ErrorHandler *errHandler = new ErrorHandler();
54  if (!astOK) {
55  if (rawPtr1) {
56  astAnnul(rawPtr1);
57  }
58  if (rawPtr2) {
59  astAnnul(rawPtr2);
60  }
61  throw std::runtime_error(errHandler->getErrMsg());
62  }
63 }

◆ escapes()

bool ast::escapes ( int  include = -1)
inline

Control whether graphical escape sequences are included in strings.

The Plot class defines a set of escape sequences which can be included within a text string in order to control the appearance of sub-strings within the text. (See the Escape attribute for a description of these escape sequences). It is usually inappropriate for AST to return strings containing such escape sequences when called by application code. For instance, an application which displays the value of the Title attribute of a Frame usually does not want the displayed string to include potentially long escape sequences which a human read would have difficuly interpreting. Therefore the default behaviour is for AST to strip out such escape sequences when called by application code. This default behaviour can be changed using this function.

Parameters
[in]includePossible values are:
  • -1 (or any negative value) to return the current value without changing it.
  • 0 to not include escape sequences,
  • 1 (or any positive value) to include escape sequences,
Returns
the previous value (or current value if include is negative).

Notes:

  • This function also controls whether the AST function astStripEscapes removes escape sequences from the supplied string, or returns the supplied string without change.
  • Unlike the AST function astEscapes, this function will not attempt to execute if an error has already occurred.

Definition at line 140 of file base.h.

140  {
141  assertOK();
142  int ret = astEscapes(include);
143  assertOK();
144  return ret;
145 }

◆ makeRadialMapping()

std::shared_ptr< Mapping > ast::makeRadialMapping ( std::vector< double > const &  center,
Mapping const &  mapping1d 
)

Construct a radially symmetric mapping from a 1-dimensional mapping.

The transform will be symmetrical about the specified center. The forward transform is as follows: input -> unitNormMap -> input norm -> mapping1d -> output norm -> unitNormMap inverse -> output -> unit vector -------------------------—> where unitNormMap is UnitNormMap(center)

The returned mapping will support forward and/or inverse transformation as mapping1d does.

Parameters
[in]centerCenter of radial symmetry
[in]mapping1d1-dimensional mapping
Returns
a mapping that is radially symmetric about the center and has nIn = nOut = center.size()
Exceptions
std::invalid_argumentif mapping1d has nIn or nOut != 1
std::runtime_errorif center is empty

Definition at line 48 of file functional.cc.

48  {
49  auto naxes = center.size();
50  if (mapping1d.getNIn() != 1) {
51  throw std::invalid_argument("mapping1d has " + std::to_string(mapping1d.getNIn()) +
52  " inputs, instead of 1");
53  }
54  if (mapping1d.getNOut() != 1) {
55  throw std::invalid_argument("mapping1d has " + std::to_string(mapping1d.getNOut()) +
56  " outputs, instead of 1");
57  }
58  auto unitNormMap = UnitNormMap(center);
