<P>
Callback interface for SQLite's user defined functions.
Each callback method receives a
<A HREF="FunctionContext.html">FunctionContext</A> object
which is used to set the function result or error code.

Example:<BR>
<PRE>
class SinFunc implements SQLite.Function {
public void function(SQLite.FunctionContext fc, String args[]) {
try {
Double d = new Double(args[0]);
fc.set_result(Math.sin(d.doubleValue()));
} catch (Exception e) {
fc.set_error("sin(" + args[0] + "):" + e);
}
}
...

SQLite.Database db = new SQLite.Database();
db.open("db", 0);
db.create_function("sin", 1, SinFunc);
...
db.exec("select sin(1.0) from test", null);
