write_n_in() [2/2] void write_n_in ( const std::vector< std::string > &  keywords, TSeq &&  records  ) const Write a subset of a homogeneous or heterogeneous sequence of records. Template Parameters Mode The write mode T The record value type for homogeneous sequences (automatically deduced) Ts... The record value types for heterogeneous sequences (automatically deduced) TSeq The sequence type (automatically deduced) Parameters records The sequence of records keywords The selection to be written Several methods allow write a sequence of records or subset of sequence of records. Analogously to write(), template parameter Mode controls the writing behavior, depending on wether the keyword to be written already exists or not. If parameter keywords is provided, then only the records for which the keyword belongs to keywords are written. This is especially handy when a unique sequence of records should be written in different HDUs. Example usage: h0.write_n(records); h1.write_n_in<RecordMode::CreateNew>({"A", "B"}, records); h2.write_n_in<RecordMode::CreateNew>({"B", "C"}, records); where h0, h1, h2 are headers of different HDUs and records is a sequence of records, like a RecordSeq.
