Changes additional information / documentation of a method in the EDMdatabase. The purpose of the user defined method signatures is to provide information about the methods and their input parameters to the users. The methods in question are Express-X mapping schemas and query functions. This is the only way to add classification and description to a query function method. For Express-X schema maps, this information may also be given by xpxDefineMethodSignature.

Arguments

1	Type	Name	Comment
2	GENERIC	methodId	The instance Id of the method to modify. This Id is an instance of the EDM_METHOD entity in the ExpressDataManager model.
3	STRING	methodClass	The type of method. Values are: "XPX" if the method is an Express-X Schema Map. "QEX" if the method is a Query Function.
4	INTEGER	returnValueDatatype
5	GENERIC	returnValueDomainId
6	LIST OF STRING	argumentNames	A NULL terminated list of argument names. Not applicable for query function methods.
7	LIST OF INTEGER	argumentDatatypes	A list of parameter data types that corresponds to the <parameterNames>. Not applicable for query function methods.
8	LIST OF GENERIC	argumentDomainIds	Optional, zero terminated buffer of parameter domainIds
9	STRING	description	Optional. A textual description of the method.
