| StreamAccessor | A StreamAccessor MethodInstance identifies an operation on the external system that returns streaming information about an external item corresponding to given Identity. Related method: GetData(). | |
| BinarySecurityDescriptorAccessor | A BinarySecurityDescriptorAccessor MethodInstance identifies an operation on the external system that returns a security descriptor for the external item corresponding to the given Identity. Related method: GetSecurityDescriptor(Identity, ILobSystemInstance). | |
| BulkSpecificFinder | A BulkSpecificFinder MethodInstance identifies an operation on the external system that returns external items corresponding to the given Identity objects. Related method: FindSpecificMultiple. | |
| BulkAssociatedIdEnumerator | A BulkAssociatedIdEnumerator MethodInstance identifies an operation on the external system that returns the identities of all external items participating in a relationship that includes the given external items. This MethodInstance is an Association. Related method: BulkEnumerateAssociatedIds. | |
| BulkAssociationNavigator | A BulkAssociationNavigator MethodInstance identifies an operation on the external system that returns external items that are related to the given set of external items. This MethodInstance is an Association. Related method: FindAssociatedMultiple. | |

Remarks
A MethodInstance can be one of several types. The type indicates to the Business Data Connectivity (BDC) service what class of operation the method supports, for example, finding one or more external items or creating a new external item.
