Package uk.ac.starlink.fits
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.-
Interface Summary Interface Description 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.WideFits Defines a convention for storing extended column data in a FITS BINTABLE extension. -
Class Summary Class Description AbstractArrayDataIO Abstract implementation of an implementation of anom.tam.util
-compatible FITS I/O handler.AbstractFitsTableWriter Abstract table writer superclass designed for writing FITS tables.AbstractWideFits Implementations of the WideFits interface.BasicInputThreadLocal ThreadLocal based on an InputFactory.BintableColumnHeader Understands how per-column metadata is stored in the headers of a FITS BINTABLE extension.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.BufferedRandomInput BasicInput implementation based on a RandomAccessFile.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 theTableBuilder
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 aStarTable
in a column-oriented FITS binary table format.FitsArrayBuilder Turns URLs which reference FITS array resources into NDArray objects.FitsConstants Utility class providing some constants and static methods related to FITS file format and starlink classes.FitsNdxHandler Turns URLs which reference FITS files or HDUs into Ndx objects.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.HealpixFitsTableWriter TableWriter implementation that writes FITS files using the HEALPix-FITS convention.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 Exception Description MappedFile.FileTooLongException Exception indicating that a file is too long to map.
