FileMemSegments Class Reference

#include <FileMemSegments.h>

Detailed Description

Mapping between an in-file (FITS binary table data unit) segment and an in-memory (column) segment for reading and writing bintable segments.

Public Member Functions
	FileMemSegments (const Segment &fileSegment, long memoryIndex=0)
	Create a mapping from an in-file segment and an in-memory position.
	FileMemSegments (long fileIndex, const Segment &memorySegment=Segment::whole())
	Create a mapping from an in-file position and an in-file segment.
const Segment &	file () const
	Get the in-file segment.
const Segment &	memory () const
	Get the in-memory segment.
long	size () const
	Get the common segment size.
void	resolve (long fileBack, long memoryBack)
	Resolve the unknown (-1) indices, given known in-file and in-memory back indices.
long	fileToMemory () const
	Compute the index offset from in-file segment to in-memory segment.
long	memoryToFile () const
	Compute the index offset from in-memory segment to in-file segment.
