Interface Parser

All Known Implementing Classes:
ParserImpl

public interface Parser

The Parser interface is intended to work with Jack-generated parsers (now JavaCC). We will specify "STATIC=false" when building Jack parsers - this specifies that the generated classes will not be static, which will allow there to be more than one parser (this is necessary in a multi-threaded server). Non-static parsers do not have to be re-initialized every time they are used (unlike static parsers, for which one must call ReInit() between calls to the parser).


Method Summary
 java.lang.String getSQLtext()
          Returns the current SQL text string that is being parsed.
 StatementNode parseStatement(java.lang.String statementSQLText)
           
 StatementNode parseStatement(java.lang.String statementSQLText, java.lang.Object[] paramDefaults)
          Parses the given statement and returns a query tree.
 

Method Detail

parseStatement

StatementNode parseStatement(java.lang.String statementSQLText,

                             throws StandardException

paramDefaults - Parameter defaults
Returns:
A new QueryTree representing the syntax of the Statement
Throws:
StandardException - Thrown on failure
