Arguments
...
| 1 | Type | Name | Comment |
| 2 | GENERIC | methodId | The instance Id of the method. This Id is an instance of the EDM_METHOD entity in the ExpressDataManager model. |
| 3 | STRING | methodType | Variable that will receive the type of method. Values are:
|
| 4 | STRING | methodName | Variable that will receive the name that was assigned to the method when it was defined with edmiDefineMethodSignature. If the method is a Query Function, the method name will be the name of the query function it self. |
| 5 | STRING | schemaName | If the method is an Express-X Schema Map, this variable will receive the name of the mapping schema. If the method is a query function, the variable will receive the name of the query schema containing the query in question, qualified with the name of the parent Express schema. |
| 6 | STRING | methodClass | Variable that will receive the optional and user defined method class. Method classification may be used to organize methods in the EDMdatabase |
| 7 | INTEGER | arguments | This variable will receive the number of input parameters for the given method. |
| 8 | INTEGER | returnValueDatatype | Variable that will receive the type of the return value from the method. This is only applicable for query function methods. |
| 9 | GENERIC | returnValueDomainId | |
| 10 | LIST OF STRING | argumentNames | A buffer that will receive a null terminated list of the input parameter names. |
| 11 | LIST OF INTEGER | argumentDatatypes | A buffer that will receive a list of the input parameter types that corresponds to the argument names in <argumentNames> |
| 12 | LIST OF GENERIC | argumentDomainIds | |
| 13 | STRING | description | Variable that will receive the user defined description of the method. |
| 14 | STRING | textualSignature | Optional, method signature in text. |
