prepRead()

virtual void lsst::afw::table::io::FitsColumnReader::prepRead ( std::size_t  firstRow, std::size_t  nRows, fits::Fits &  fits  )

inlinevirtual

Optionally read ahead and cache values from multiple rows.

Subclasses are not required to implement this method; if they do, they should indicate to readCell that cached values should be used instead. Subclasses should not assume that prepRead will always be called, however.

Parameters

[in]	firstRow	Index of the first row to read.
[in]	nRows	Number of rows to read.
[in]	fits	FITS file manager object.

readCell()

virtual void lsst::afw::table::io::FitsColumnReader::readCell ( BaseRecord &  record, std::size_t  row, fits::Fits &  fits, std::shared_ptr< InputArchive > const &  archive  ) const

pure virtual

Read values from a single row.

Parameters

[in,out]	record	Record to populate.
[in]	row	Index of the row to read from.
[in]	fits	FITS file manager object.
[in]	archive	Archive holding persisted objects, loaded from other HDUs. May be null.

Implemented in lsst::afw::table::PersistableObjectColumnReader< T, Setter >.
