◆ choice()

Get a choice from the user.

The choice function to be used can be set using setChoiceFunc. It can, for instance, be done by ObjectController. Initially no choice function is set. In that case it returns the first choice (so that should be the default choice). If choices is zero length, an empty string is returned.

◆ ostreamChoice()

static String casacore::Choice::ostreamChoice ( std::ostream &  ,
const String descriptiveText,
const Vector< String > &  choices 
)
