public class SqlStatementParser
extends java.lang.Object

Handles parsing of SQL statements to derive parsing information. This class encapsulates logic to select a parser based on a particular dialect.

The call to fetch the singleton parser is synchronized to guarantee visibility across all threads. Also, we final variables for all instances to avoid unnecessary object creation, as the parsing function is called potentially many times.

Method Summary
