Properties

	Name	Description
	AvailableRestrictions	Gets or sets all the restrictions that are available for the current type.
	AvailableRestrictionsList	Gets a list of all the restrictions that are available for the current type.
	ClassId	Gets or sets the class ID of the attribute.
	Identifier	Gets or sets the identifier name that uniquely identifies the current type.
	IdentifierList	Gets a list of identifiers that uniquely identify the current type.
	RequiredOrdering	Gets or sets the required ordering for the current mapped type.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	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.)
	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.
