public final class UnresolvedExpression extends TypedExpression
TypedExpression that represents an invalid or unresolvable identifier. An application might encounter this class if it has passed an implementation of the XMLParserCallback interface in a call to a SyntaxObject.fromSyntax or MdmMetadataProvider.importXML method. If the methods of the XMLParserCallback implementation return XMLParserCallback.ERROR_BY_INVALIDATING, then Oracle OLAP does not throw an exception when it encounters an invalid or unresolvable identifier. Instead, it marks the object as invalid and continues parsing the XML or producing the SyntaxObject. However, if the application gets an Expression for the invalid object, that Expression is an instance of UnresolvedExpression.| Modifier and Type | Method and Description |
