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