Detailed Description

template<typename T>
class vil_nitf2_choose_field_value< T >

Functor vil_nitf2_choose_field_value defines a function that sets its out parameter to a value of one of two fields of a field sequence.

The field chosen is determined by the evaluating the functor passed as argument 'choose_tag_1_predicate': tag_1 is chosen if it evaluates to true; tag_2, otherwise.
