TYPES

public static final Map<String,Class<?>> TYPES

A llokup-table for binary data types to java data classes.

Constructor Detail

TableTools

public TableTools()

Method Detail

deduceClass

public static Class<?> deduceClass(String type)

From the value of a TFORM header entry, we deduce the java class type of the column. Arrays are described by their parental class (e.g TFORM='25E' would return Float rather than Float[]). Complex numbers are always represented as a double pair, while array pointers are returned as Long. Bits are returned as Booleans.

Returns:

null if an unknown type is encountered.

parseHeader

public static Map<String,Class<?>> parseHeader(nom.tam.fits.TableHDU tab)
                                        throws nom.tam.fits.FitsException

We read a table header and return the meta information on the data format as a mapping of column names to java class types. Arrays are described by their parental class (e.g TFORM='25E' would return Float rather than Float[]). Complex numbers are always represented as a double pair, while array pointers are returned as Long. Bits are returned as Booleans.

Throws:

nom.tam.fits.FitsException
