Class lsst::meas::base::FlagHandler

class FlagHandler

Utility class for handling flag fields that indicate the failure modes of an algorithm.

The typical pattern for using FlagHandler within an Algorithm is:

• Add a FlagHandler object as a data member.

• Create a FlagDefinitionList to specify the name and doc for each flag Add a “general” failure flag if one is needed (this indicates that some failure occurred). Add specific error flags for each type of error (these indicate a specific failure).

• Initialize the FlagHandler data member within the Algorithm’s constructor, using the static addFields method to add the flags from the FlagDefinitionList to the schema.

See PsfFluxAlgorithm for a complete example.
