parseStatement

public QueryPart parseStatement(Statement statement,
                                String query,
                                FunTable funTable,
                                boolean strictValidation)

Parses a query, with specified function table and the mode for strict validation(if true then invalid members are not ignored).

This method is only used in testing and by clients that need to support customized parser behavior. That is why this method is not part of the Connection interface.

See test case mondrian.olap.CustomizedParserTest.

Parameters:

statement - Evaluation context

query - MDX query that requires special parsing

funTable - Customized function table to use in parsing

strictValidation - If true, do not ignore invalid members

Returns:

Query the corresponding Query object if parsing is successful

Throws:

MondrianException - if parsing fails

createParser

protected MdxParserValidator createParser()
