Constructor
| TMDBElementId aElementId |
| IMPORT_C TMDBAttributeFlags | Attributes | ( | ) | const |
Returns the Attributes of an object of this type.
Attributes express database access rights for the data of this element
| IMPORT_C void | ClearAttributes | ( | TMDBAttributeFlags | aAttributes | ) |
Clears one or more attributes
| TMDBAttributeFlags aAttributes |
| IMPORT_C TMDBElementId | ElementId | ( | ) | const |
Returns the ElementId of an object of this type.
The TypeId is
<TableId><ColumnId><RecordId>
This identifies the meaning of the field in the database schema It also identifies the type of the data stored in this element and the instance of the type
| IMPORT_C TBool | IsNull | ( | ) | const |
Queries the state of the field value
Returns ETrue if the value of the element is not set Returns EFalse if the element contains a value
| IMPORT_C TBool | IsSetAttribute | ( | TMDBAttributeFlags | aAttributes | ) | const |
Queries the attributes
Returns ETrue if all queried attributes are set Returns EFalse if any queried attribute is not set.
| TMDBAttributeFlags aAttributes |
| IMPORT_C TInt | RecordId | ( | ) | const |
Returns the RecordId of an object of this type.
The RecordId is part of the ElementId <x><x><RecordId>
It identifies a particular instance of this type of Element in the database
| IMPORT_C void | SetAttributes | ( | TMDBAttributeFlags | aAttributes | ) |
Sets one or more attributes
| TMDBAttributeFlags aAttributes |
| IMPORT_C void | SetElementId | ( | TMDBElementId | aElementId | ) |
Sets the ElementId
| TMDBElementId aElementId |
| IMPORT_C void | SetRecordId | ( | TInt | aRecordId | ) |
Sets the RecordId
| TInt aRecordId |
| IMPORT_C void | SetTypeId | ( | TMDBElementId | aElementId | ) |
Sets the TypeId
| TMDBElementId aElementId |
| IMPORT_C TMDBElementId | TableId | ( | ) | const |
Returns the TableId of an object of this type.
The TableId is part of the ElementId
<TableId><x><x>
It identifies the table in the database that holds the data contained in this element
| EXP_DATA_VTABLE TCDFieldValueTypes | Type | ( | ) | [pure virtual] |
Queries the type of the field value
Returns the enumeration TCDFieldValueTypes that represents the value that can be stored in this element
| IMPORT_C TMDBElementId | TypeId | ( | ) | const |
Returns the TypeId of an object of this type.
The TypeId is
<TableId><ColumnId><x>
This identifies the meaning of the data in this element in the database schema It also identifies the type of the data contained in this element
For an element that is a Table or a Record, the ColumnId field will be set to
KCDMaxColumnId
