Class VariableFitsTableWriter

java.lang.Object

uk.ac.starlink.table.StreamStarTableWriter

uk.ac.starlink.fits.AbstractFitsTableWriter

uk.ac.starlink.fits.VariableFitsTableWriter

All Implemented Interfaces:

MultiStarTableWriter, StarTableWriter

Deprecated.

Use uk.ac.starlink.votable.UnifiedFitsTableWriter instead

@Deprecated
public class VariableFitsTableWriter
extends AbstractFitsTableWriter

TableWriter which writes FITS BINTABLEs with variable-length arrays where appropriate. Array-valued columns in the input StarTable which are declared with variable shapes (the last element of ColumnInfo.getShape() is negative) will be written in the output FITS file using the 'P' or 'Q' data type specifier with the actual data written in the BINTABLE extension heap - see the FITS document for details. Any other columns will get written in just the same way as by the FitsTableWriter.

Strings and String arrays ('A' descriptor) are not currently written in variable-length form.

Constructor Detail

VariableFitsTableWriter

public VariableFitsTableWriter()

Deprecated.

Constructs a writer with default characteristics. It chooses sensibly between using 'P' and 'Q' format.

VariableFitsTableWriter

@Deprecated
public VariableFitsTableWriter(Boolean longIndexing,
                                           boolean allowSignedByte,
                                           WideFits wide)

Deprecated. allows some configuration options but not others; use no-arg constructor and configuration methods instead

Deprecated custom constructor.

Method Detail

setStoragePolicy

public void setStoragePolicy(StoragePolicy storagePolicy)

Deprecated.

Sets the storage policy which will be used for temporary storage during writing. Temporary storage is required for the heap contents while the table body itself is being written. By default the system default storage policy is used.

Parameters:

storagePolicy - policy to use

setLongIndexing

public void setLongIndexing(Boolean longIndexing)

Deprecated.

Sets whether this writer will use P or Q format descriptors for writing variable-length arrays.

Parameters:

longIndexing - TRUE for 'Q' (64-bit) indexing into the heap, FALSE for 'P' (32-bit) indexing into the heap, null to make a sensible choice

getLongIndexing

public Boolean getLongIndexing()

Deprecated.

Indicates whether this writer will use P or Q format descriptors for writing variable-length arrays.

Returns:

TRUE for 'Q' (64-bit) indexing into the heap, FALSE for 'P' (32-bit) indexing into the heap, null to make a sensible choice

looksLikeFile

public boolean looksLikeFile(String location)

Deprecated.

Always returns false.

Parameters:

location - the location name (probably filename)

Returns:

true iff it looks like a file this writer would normally write

createSerializer

protected FitsTableSerializer createSerializer(StarTable table)
                                        throws IOException

Deprecated.

Description copied from class: AbstractFitsTableWriter

Provides a suitable serializer for a given table. Note this should throw an IOException if it can be determined that the submitted table cannot be written by this writer, for instance if it has too many columns.

Specified by:

createSerializer in class AbstractFitsTableWriter

Parameters:

table - table to serialize

Returns:

FITS serializer

Throws:

IOException - if the table can't be written
