Description

Interface Summary

BasicInput	Interface defining the basic data input operations required for the FITS reading classes.
FitsTableSerializer	Defines an object which can serialize a table to a FITS HDU.

Class Summary

AbstractArrayDataIO	Abstract implementation of an implementation of a nom.tam.util-compatible FITS I/O handler.
AbstractFitsTableWriter	Abstract table writer superclass designed for writing FITS tables.
BintableStarTable	An implementation of the StarTable interface which uses a FITS BINTABLE extension.
BlockMappedInput	Random-access BasicInput implementation that maps a given region of a file as a number of byte buffers.
ColFitsStarTable	StarTable based on a single-row FITS BINTABLE which contains the data for an entire column in each cell of the table.
ColFitsTableBuilder	Implementation of the TableBuilder interface which reads tables stored in column-oriented FITS binary table format.
ColFitsTableSerializer	Object which can serialize a StarTable to a data stream as a one-row FITS file in which each element contains an entire column of the table.
ColFitsTableWriter	Handles writing of a StarTable in a column-oriented FITS binary table format.
FitsConstants	Utility class providing some constants and static methods related to FITS file format and starlink classes.
FitsStarTable	An implementation of the StarTable interface which uses FITS TABLE or BINTABLE extensions.
FitsTableBuilder	Implementation of the TableBuilder interface which gets StarTables from FITS files.
FitsTableWriter	Handles writing of a StarTable in FITS binary format.
HduFitsTableWriter	TableWriter which writes a single extension BINTABLE HDU containing the table.
HeaderCards	Controlled access to a collection of FITS header cards.
InputFactory	Represents a sequence of bytes, and can create BasicInput objects to read it.
MappedFile	Provides mapped access to a data buffer using a single mapped byte buffer, compatible with nom.tam.util classes.
MultiMappedFile	ArrayDataIO implementation which works by mapping but is capable of splitting a file up into multiple mapped sections.
SimpleMappedInput	Random-access BasicInput implementation that maps a given region of a file as a monolithic byte buffer.
StandardFitsTableSerializer	Class which knows how to do the various bits of serializing a StarTable to FITS BINTABLE format.
Unmapper	Attempts to free resources from a MappedByteBuffer.
VariableFitsTableSerializer	FitsTableSerializer which can write variable array-valued columns using the 'P' or 'Q' TFORM formatting characters.
VariableFitsTableWriter	TableWriter which writes FITS BINTABLEs with variable-length arrays where appropriate.

Exception Summary

MappedFile.FileTooLongException

Exception indicating that a file is too long to map.

Package uk.ac.starlink.fits Description

Classes for general FITS handling, including NDX, NDArray and StarTable implementations. Some of these classes use the nom.tam.fits package for low-level FITS access, though several of them do most of the handling in customised ways themselves for efficiency reasons.
