Method Details

isRecursive

boolean isRecursive()

INTERNAL:

prescan

void prescan(QueryBuilder builder,
 List arguments)

INTERNAL: This method will be called before building the query. It is used mainly for analyzing the predicate.

boolean buildQuery(QueryBuilder builder,
 List expressions,
 List arguments)
            throws InvalidQueryException

INTERNAL: Registers JDOExpressionsIF for this predicate with the query builder.

Returns:

true if predicate was mapped to JDO expression; false if the predicate could not be mapped to an JDO expression.
