EdmiError edmiDeleteMethodSignatureBN(SdaiString methodType,
                                       SdaiString methodName,
                                       SdaiString schemaName);

Deletes any additional information / documentation of a method from the EDMdatabase. A method signature is an instance of the EDM_METHOD entity in the ExpressDataManager model. A method is either an Express-X Mapping Schema or a Query Function. The method signature contains information about the required input parameters for each method. It may also contain a more general and descriptive text for documentation purposes. Query functions already have their parameters defined in the query function signature. Hence, they implicitly get a method signature definition in the ExpressDataManager model and they may therefore not be deleted. Therefore this method is only applicable on Express-X mapping schemas.

Arguments

Type	Name	Comment
SdaiString	methodType	"XPX" is currently the only applicable method type.
SdaiString	methodName	The name that was assigned to the Express-X Mapping Schema method when it was defined.
SdaiString	schemaName	The name of the Express-X Schema Map.

Return Value
