Parser (Apache Derby V10.14 Internals)

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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.lang.String`	`getSQLtext()`	Returns the current SQL text string that is being parsed.
`Visitable`	`parseSearchCondition(java.lang.String sqlFragment)`	Parse an SQL fragment that represents a `<search condition>`.
`Visitable`	`parseStatement(java.lang.String statementSQLText)`
`Visitable`	`parseStatement(java.lang.String statementSQLText, java.lang.Object[] paramDefaults)`	Parses the given statement and returns a query tree.

Visitable parseStatement(java.lang.String statementSQLText,
                         java.lang.Object[] paramDefaults)
                  throws StandardException
```
    Parses the given statement and returns a query tree. The query tree at this point is a simple syntactic translation of the statement. No binding will have taken place, and no decisions will have been made regarding processing strategy.
    
    Parameters:
    
    statementSQLText - The Statement to parse.
    
    paramDefaults - Parameter defaults
    
    Returns:
    
    A new QueryTree representing the syntax of the Statement
    
    Throws:
    
    StandardException - Thrown on failure
  - parseStatement
```
Visitable parseStatement(java.lang.String statementSQLText)
                  throws StandardException
```
    Throws:
    
    StandardException
  - parseSearchCondition
```
Visitable parseSearchCondition(java.lang.String sqlFragment)
                        throws StandardException
```
    Parse an SQL fragment that represents a <search condition>.
    
    Parameters:
    
    sqlFragment - the SQL fragment to parse
    
    Returns:
    
    a parse tree representing the search condition
    
    Throws:
    
    StandardException - if the SQL fragment could not be parsed
  - getSQLtext
```
java.lang.String getSQLtext()
```
    Returns the current SQL text string that is being parsed.
    
    Returns:
    
    Current SQL text string.
