public abstract class GenericStarDatabase
extends AbstractSql

A class that allows access to databases holding stellar information. As it extends the GenericSql class, only a single bridge, i.e. a single database-type can be loaded per VM (or, per classloader). This class knows how to convert the relevant fields found in the database into SimpleStar objects out of a result set. Special databases using callable statements etc. must subclass this class. This class is therefore abstract, daughter must implement how to convert a central star, given as a SimpleStar and a (circular) field into a result-set.

Constructor Detail

GenericStarDatabase

public GenericStarDatabase(Map<String,String> prop)

Constructs a new generic star database. The connection data are part of the parent class, while this class takes expressions on how to convert individual results from the result set to SimpleStars. Keys that are not defined mean that they are not present in the database.

Method Detail

getCircularField

public abstract ResultSet getCircularField(Star center,
                                           double radius)

Takes a central star and a circular radius around it to convert it to a database query result set, which is then passed to the convertResultToStarList(java.sql.ResultSet) method.

Parameters:

center - The central star/position.

radius - Radius of the circular field around the center, degrees.

convertResultToStarList

public List<Star> convertResultToStarList(ResultSet rs)

Converts a result set to a list of SimpleStar objects. Only the fields that can be set using the database result are set.

evaluate

private static Number evaluate(String node,
                               ResultSet row)

Converts the current result set row into a number.
