Comments:

The class GeomFeatSetC is a set of geometric features of class GeomFeatC of uniform gf type, together with a descriptor of the feature type.

Additionally, extra feature attributes can be included, as well as covariances for the features. The covariances are currently (somewhat idiosyncratically) in a mxn matrix M which is a square root of the covariance matrix; m is the number of underlying error parameters, and n is the number of feature measurements. The covariance matrix is given by M.T() * M.

SArray1dC data;

GeomFeatSetC(const GfSetC gf_set,const int extra_meas = 0,const bool errors_with_data = false)

constructor from gf set If extra_meas > 0, the next extra_meas values after the feature are read in. I.e. it is a way of incorporating extra attributes for the features. If errors_with_data, it will look for a 2D array

GeomFeatSetC(const GfFeatT type,const IntT size)

constructor for set to be filled later

GeomFeatSetC(const GfFeatT type,const SArray1dC<VectorC> pts)

constructor from array of points

GeomFeatSetC(const GeomFeatSetC & set)

~GeomFeatSetC()

destructor

GeomFeatSetC & operator=(const GeomFeatSetC & set)

assignment

IntT Size() const

size of set

const GeomFeatC & operator[](const IntT i) const

access to const set element

GeomFeatC & operator[](const IntT i)

access to set element

SArray1dC<VectorC> GenPts() const

generates a vector array of the feature points

SArray1dC<VectorC> GenCG() const

generates a vector array of the feature centres of gravity

IntT Field(StringC gf_format)

returns position of feature in gf format string

void SetType(const GfFeatT new_type)

assign gf type

GfFeatT Type() const

returns gf type of feature

IntT NoOfPts() const
