DataMappedObjectTypeAttribute Class
Specifies that an interface or class represents a mapped object type. A mapped object type is an API that exposes a strongly-typed view of a particular underlying data source–specific object.

Properties
Name | Description | |
---|---|---|
AvailableRestrictions | Gets or sets all the restrictions that are available for the current type. | |

Methods
Name | Description | |
---|---|---|
Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) | |
Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Explicit Interface Implementations
Name | Description | |
---|---|---|
_Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) | |
_Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) | |
_Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) | |
_Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |

Remarks
The mappings between data-source types and generic types are specified in the data object support XML file. For example, the mapped type whose name is TableColumn found in the <MappedType> element is the generic type that could be mapped to a data-source type called Column that is found in the <Type> element.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
