All Implemented Interfaces:

Direct Known Subclasses:

Ucac4DatabaseFeeder.Ucac4Catalog

public abstract class BinaryCatalog
extends BinaryTable<Star>

This class reads binary number data from a file, data might be stored in big endian (default for java) or even little endian. The data structure must be specified with a dataline property. This string consists of letters BSILFD for byte, short,integer,long, float, and double data type. A letter K followed by a number indicates that the appropriate number of bytes should be skipped. As an example, a dataline of IIFK10F would be interpreted as a single data block consisting of two integers (each 4 bytes), followed by a float (4 bytes), then reading should skip over 10 bytes before continuing reading a single float. The resulting data array consists of 4 numbers.
