Syntax

[SerializableAttribute]
public sealed class UOMBaseClass : AFObject, 
	IComparable<UOMBaseClass>

<SerializableAttribute>
Public NotInheritable Class UOMBaseClass
	Inherits AFObject
	Implements IComparable(Of UOMBaseClass)

Dim instance As UOMBaseClass

[SerializableAttribute]
public ref class UOMBaseClass sealed : public AFObject, 
	IComparable<UOMBaseClass^>

[<SealedAttribute>]
[<SerializableAttribute>]
type UOMBaseClass =  
    class
        inherit AFObject
        interface IComparable<UOMBaseClass>
    end

The UOMBaseClass type exposes the following members.

Properties

	Name	Description
	Class	This read-only property is the base UOMClass which is raised to the power specified by the Power property.
	Database	This read-only property allows access to the UOMDatabase associated with this object.
	ID	Read-only property that provides a unique identifier for the object to be used for quick access that is not dependent upon the index. (Inherited from AFObject.)
	Identity	This read-only property contains identity of the object. (Inherited from AFObject.)
	IsDeleted	This read-only property indicates whether the object has been deleted. (Inherited from AFObject.)
	Name	Read-only property that identifies the name of the object.
	PISystem	This read-only property allows access to the PISystem associated with this object. (Inherited from AFObject.)
	Power	This read/write property represents the power of the corresponding base Class property.
	UniqueID	Read-only property that provides the object's ID as a String. (Inherited from AFObject.)

Methods

	Name	Description
	CompareTo(Object)	Compares this instance with a specified Object. (Inherited from AFObject.)
	CompareTo(AFObject)	Compares this instance with a specified AFObject. (Inherited from AFObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current object. (Inherited from AFObject.)
	Equals(AFObject)	Indicates whether the current object is equal to another object of the same type. (Inherited from AFObject.)
	GetHashCode	Gets the hash code for this instance of the object which is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from AFObject.)
	GetPath	Returns the full path to the object, using just the names. (Inherited from AFObject.)
	GetPath(AFObject)	Returns the path to the object relative from another object. (Inherited from AFObject.)
	GetPath(AFEncodeType, AFObject)	Returns the path to the object relative from another object, using the name and/or id as specified by encodeType. (Inherited from AFObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Persist	This method returns the persistence string for the object. (Inherited from AFObject.)
	ToString	Returns a String that represents the current object. (Overrides AFObjectToString.)

Remarks

A UOMBaseClass object is used to define a UOMClass in terms of a base UOMClass. The UOMBaseClass object contains the base UOMClass and its associated power. For example, Density is based on Mass / Volume, resulting in collection of base UOM classes of {Mass=1, Length=-3}.
