47 *
48 * There are vast amounts of textual astronomical data, typically user is
49 * interested in a small subset, which is the result from carrying out a query.
50 * A query can be composed of one or more filters, for example, the user could
51 * query the database for all stars of visual magnitude down to 6.5 that lie
52 * between right ascensions 0 h to 2 h, and between declinations of 45 to 90 degrees.
53 *
54 * Astro application uses JAXP to query astronomical data saved in an XML dataset.
55 * A FilterFactory implementation creates filter(A filter is an instance of a JAXP
56 * TransformerHandler) from an XSL stylesheet.
57 * A InputSourceFactory implementation creates a new sax input source from an XML file.
58 * AstroProcessor leverages InputSourceFactory to parse catalog.xml, which saves
59 * textual astronomical data, and then creates filters with specified parameters
60 * from FilterFactory, all of the filters are chained together, AstroProcessor
61 * appends the HTML filter at the end of filter chain, and hooks up the chain to
62 * the input source, finally processes and outputs to the user specified output file.
63 *
64 * AstroTest drives AstroProcessor to run the specified queries(total 4 in setup),
65 * and then compares the output with the golden files to determine PASS or FAIL.
66 * It provides variant implementations of FilterFactory and InputSourceFactory to
67 * AstroProcessor to test different JAXP classes and features.
