Detailed Description

Simplified interface to create and write to FITS random groups.

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

General knowledge of FITS binary and ASCII tables.

Etymology

Synopsis

Like FITSTableWriter except that this must be the first HDU and all "columns" in the description must have the same type, i.e. float.

Example

Motivation

To Do

Constructor & Destructor Documentation

casa::FITSGroupWriter::FITSGroupWriter	(	const String &	fileName,
		const RecordDesc &	description,
		uInt	nrows,
		const Record &	extraKeywords,
		Bool	freeOutput = `True`
	)

Since this must always be the first HDU, there is no point in constructing it with a FitsOutput.

description indicates the names of the random groups parameters. nrows is a synonym for ngroups. Use extraKeywords to indicate any keywords not automatically created (SIMPLE, BITPIX, NAXIS*, EXTEND, BLOCKED, GROUPS, PCOUNT, GOUNT, ORIGIN, END). If freeOutput is True, file will be deleted by the destructor. You might not want this to happen if you are going to write any extensions to the same fits file. You can get the FitsOutput used here from write()

casa::FITSGroupWriter::~FITSGroupWriter ( )

casa::FITSGroupWriter::FITSGroupWriter ( ) [private]

Undefined and inaccessible.

Member Function Documentation

void casa::FITSGroupWriter::check_error ( const char * extra_info = 0 ) [private]

Checks error status of writer_p and group_p.

Cleans up and throws an exception if bad.

FITSGroupWriter& casa::FITSGroupWriter::operator= ( const FITSGroupWriter & ) [private]

RecordInterface& casa::FITSGroupWriter::row ( ) [inline]

Set the values for the current group.

References row_p.

void casa::FITSGroupWriter::write ( )

Write the current group (row()).

FitsOutput* casa::FITSGroupWriter::writer ( ) [inline]

Don't delete this out from under us!
