Represents a BCD object that contains a collection of BCD elements. Each BCD object is identified by a GUID.

Syntax

class BcdObject
{
  string StoreFilePath;
  string Id;
  uint32 Type;
};

Properties

The BcdObject class has these properties.

Id

Data type: string

Access type: Read-only

Qualifiers: Key

The GUID of this object, unique to this store, in string form.

StoreFilePath

Data type: string

Access type: Read-only

Qualifiers: Key

The full path to the store. If this parameter is an empty string (""), the method uses the system store.

Type

Data type: uint32

Access type: Read-only

The object type. The upper 4 bits represent the object type. The meaning of the lower 28 bits varies with object type.

• BCD_OBJECT_TYPE_APPLICATION (0x1rtaaaaa) is an object type for a boot environment application, functional usage of the application and the image type. The next four bits (24-27) are reserved, and the following four bits (20-23) specify the type of image (0x1=Firmware, 0x2=Boot, 0x3=Legacy Loader, 0x4=Real Mode code). The lowest 20 bits define the application type (0x1=Firmware boot manager, 0x2=Windows boot manager, 0x3=Windows boot loader, 0x4=Windows resume application, 0x5=Memory tester, 0x6=Legacy NtLdr, 0x7=Legacy SetupLdr, 0x8=Boot sector, 0x9=Startup module, 0xa=Generic application.)
• BCD_OBJECT_TYPE_INHERITED (0x2nnnnnnn) describes a set of data elements which can be inherited from a BCD object for a boot application or from another inheritable object.

Remarks

To retrieve an object instance, use one of the following static methods of the BcdStore class: CreateStore, OpenStore, or ImportStore.
