public sealed class Typedef : DOFType, 
	DOFTypeContextResolver

The DOFTypeTypedef type exposes the following members.

	Name	Description
	DOFTypeTypedef	Construct a typedef that can be used for a forward reference.
	DOFTypeTypedef(DOFType)	Construct a typedef that is an alias for another existing type.

	Name	Description
	defineAs	Finalize a forward reference.
	Equals	Typedefs are equal only if their references are equal. (Overrides DOFTypeEquals(Object).)
	getEncoding	(Overrides DOFTypegetEncoding.)
	GetHashCode	(Overrides DOFTypeGetHashCode.)
	getInstance	(Overrides DOFTypegetInstance(DOFPacket).)
	getMaxLength	(Overrides DOFTypegetMaxLength.)
	getMinLength	(Overrides DOFTypegetMinLength.)
	getSubtypes	(Overrides DOFTypegetSubtypes.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	getTypeID	(Overrides DOFTypegetTypeID.)
	isDefined	(Overrides DOFTypeisDefined.)
	marshal	(Overrides DOFTypemarshal(DOFTypeContext, DOFPacket).)
	ToString	(Overrides DOFTypeToString.)

There are two primary cases for using this class: first, in order to declare an alias to an existing type for clarity of code and documentation; and second, in order to declare a forward reference in order to facilitate self-referential types.

In the first case the constructor is passed the type to create the reference to. The class is fully defined at that point. All queries to the Typedef will return information from the referenced type, and in fact there is no clear way of determining that there is any reference type at all.

In the second case the constructor is given no information. The type is only partially defined, as DOFType.isDefined() will return

false
