TypeDefinitions Extent (System_Runtime Module)
[This content is no longer valid. For the latest information on "M", "Quadrant", SQL Server Modeling Services, and the Repository, see the Model Citizen blog.]
Stores type definitions. This is a specialized extent in the Types/TypeDefinitions/TypeReferences hierarchy.
Fields
The following table lists the fields in the TypeDefinitions extent.
| Column | Type | Required | Description |
|---|---|---|---|
Folder |
yes |
The Modeling Services Folder that is associated with the type. |
|
Id |
yes |
The identifier of the type. |
|
Kind |
Integer16 |
yes |
An enumeration value between 1 and 5 that describes the kind of the type. These numeric values are equivalent to class, value, enumeration, delegate, and interface. |
BaseType |
The base type signature for the type. |
||
Namespace |
yes |
The namespace of the type. |
|
Access |
Integer16 |
yes |
An enumeration value between 0 and 6 that describes the access restrictions for the type. These numeric values are equivalent to compiler, private, family and assembly, assembly, family, family or assembly, and public. |
ContainingType |
The type signature that contains the type. |
||
IsAbstract |
Logical |
yes |
A bit flag that indicates that the type is abstract, meaning that no direct instances of the type are possible. |
IsSealed |
Logical |
yes |
A bit flag that specifies that the type is sealed, meaning that other type definitions cannot derive from the type. |
IsToolSpecialName |
Logical |
yes |
A bit flag that specifies that the type name is special and has a reserved use by tools other than the common language runtime. |
IsRuntimeSpecialName |
Logical |
yes |
A bit flag that specifies that the type name is special and has a reserved use by the common language runtime. |
InitializeTypeBeforeFields |
Logical |
yes |
A bit flag that specifies that the type requires initialization before its fields are initialized. This supports static method calls. |
IsSerializable |
Logical |
yes |
A bit flag that specifies that the type is serializable. |
Layout |
Integer16 |
yes |
An enumeration value between 0 and 2 that guides the loader in constructing the layout of the type. These numeric values are equivalent to automatic, sequential, and explicit. |
Documentation |
Text |
The XML Document fragment for the type. Note that this is not yet populated by the LoadAssembly.exe tool. |
|
Attributes |
Text |
The custom attributes for the type. Note that this is not yet populated by the LoadAssembly.exe tool. |
