Remarks

This method finds which parm methods are available in a specific table in the create scenarios for the Axd classes.

Examples

The following example shows how this method is used in the AxdBaseCreate.buildParmMethodsMap method:

protected Map buildParmMethodsMap(classId _classId,  
                                  QueryBuildDataSource _qbds) 
{ 
    Set             fieldsInQuerySet; 
    SetEnumerator   setEnumerator; 
    Map             parmMethodsMap; 
    identifiername  parmMethodName; 
    SysDictClass    sysDictClass; 
    #axd 
    fieldsInQuerySet = AxdBase::fieldsInDataSourceSet(_qbds); 
    if (fieldsInQuerySet) 
    { 
        sysDictClass   = new SysDictClass(_classId); 
        parmMethodsMap = new Map(Types::String,Types::Integer); 
        setEnumerator  = fieldsInQuerySet.getEnumerator(); 
 
        while (setEnumerator.moveNext()) 
        { 
            parmMethodName = #axdParmPrefix + 
   fieldid2name(tableId,setEnumerator.current()); 
            if (sysDictClass.isMethodActual(parmMethodName)) 
            { 
                parmMethodsMap.insert(parmMethodName,_classId); 
            } 
        } 
    } 
    else 
    { 
        parmMethodsMap = AxInternalBase::parmMethods(_classId); 
    } 
    return parmMethodsMap; 
}
