Detailed Description

Projection-dependent weights.

The weight for a given projection can be set with setWeight().

Internally, the weights are regrouped by largest coordinate index in different std::map objects. This is useful for use with CBC.

Member Function Documentation

virtual void LatCommon::ProjectionDependentWeights::format ( std::ostream &  os) const

Identifies the type of weights, formats them and outputs them on os.

Deriving classes should identify themselves in the output.

Implements LatCommon::Weights.

std::istream & operator>> ( std::istream &  is,
ProjectionDependentWeights weights 

Reads formatted projection-dependent weights into the object weights.

The input should be a sequence of projection-to-weight mappings, of the format:

<match1>: <weight1>, <match2>: <weight2>, ...

where <weightn> is the weight (a floating point number) associated to the projection-match <matchn>, and <matchn> is one of:

  • a set of coordinates, as specified in operator>>(std::istream&, LatCommon::Coordinates&) to explicitly set the weight for the projection that correspond to these coordinates;
  • the string order m to implicitly set the weights of projections of order m;
  • the string default to set the default weight for other projections.
Comments can be appended to any line after a # character.
The match-weight pairs can be separated by commas and/or whitespace (including newlines).
The colons (:) can be replaced with => or ->.
