Constructor Detail
JdbcJDOQLCompiler
public JdbcJDOQLCompiler(JdbcStorageManager sm)(Code)




Method Detail
compile
public JdbcCompiledQuery compile(QueryDetails q)(Code)
Compile a QueryDetails into a JdbcCompiledQuery ready to run.



compileParallelFetch
public SqlExp compileParallelFetch(QueryDetails q)(Code)
Create a filter exp for a collection query.



compileParams
public static void compileParams(QueryParser qParser, SqlStruct sqlStruct)(Code)
This nasty code has to find the bits of SQL occupied by parameter expressions that could be null. They may need to be converted into 'is null' or 'is not null' or removed completely (for shared columns) if the corresponding parameter is null.



doFinalSql
public static void doFinalSql(SqlStruct sqlStruct, SelectExp root, SqlDriver driver)(Code)



findJoinBefore
public static Join findJoinBefore(Join aJoin, Join root)(Code)



getCandidateSelectExp
public SelectExp getCandidateSelectExp()(Code)
Get the select for the candidate class. All other SqlExp's for the query are reachable from this.



getJmd
public ModelMetaData getJmd()(Code)



getQParser
public QueryParser getQParser()(Code)



getVisitor
public JDOQLNodeToSqlExp getVisitor()(Code)



reOrderJoinExp
public static void reOrderJoinExp(FetchGroup fg, SelectExp se)(Code)



reinit
public void reinit()(Code)
Get this compiler ready to compile more queries. This is called before it is returned to the pool.
