Interface FitsTableSerializerConfig

public interface FitsTableSerializerConfig

Aggregates configuration options for FITS table serialization.

Since:

13 May 2021

Method Summary

Modifier and Type	Method and Description
boolean	allowSignedByte() Indicates how byte values will be written.
boolean	allowZeroLengthString() Indicates whether columns with TFORMn=0A may be output.
byte	getPadCharacter() Returns the byte value with which under-length string (character array) values should be padded.
WideFits	getWide() Returns the convention for representing over-wide tables.

Method Detail

allowSignedByte

boolean allowSignedByte()

Indicates how byte values will be written. If true, byte values are written as FITS unsigned bytes with an offset as discussed in the FITS standard (TFORM=B, TZERO=-128); if false, they are written as signed shorts (TFORM=I).

Returns:

true to write as bytes, false to write as shorts

allowZeroLengthString

boolean allowZeroLengthString()

Indicates whether columns with TFORMn=0A may be output. Such columns are explicitly permitted by the FITS standard, but they cause failures in some versions of CFITSIO.

Returns:

false to block TFORMn=0A column output, true to allow it

getWide

WideFits getWide()

Returns the convention for representing over-wide tables.

Returns:

wide table convention, or null to avoid writing wide tables

getPadCharacter

byte getPadCharacter()

Returns the byte value with which under-length string (character array) values should be padded. This should normally be one of 0x00 (ASCII NUL) or 0x20 (space).

Returns:

padding value for character array data
