VelocityDbComparerKey Class

The base class of for comparing persistent objects. If the Key objects implements IComparable then the NodeKeys are compared that way, otherwise the Id are compared

Type Parameters

Key: The type of keys to compare

The VelocityDbComparerKey type exposes the following members.

Constructors

	Name	Description
	VelocityDbComparerKey	Initializes a new instance of the VelocityDbComparerKey class

Properties

	Name	Description
	AddOidCompare	The default compare compares the object Oid's but subclasses may not want to do so as a last compare before declaring objects as being equal.
	OidPartOfComparisonBytes	Is the Oid part of the comparison bytes? If so, we don't need to do a separate Oid compare when Oid is part of compare

Methods

	Name	Description
	Compare(Key, Key)	If the Key objects implements IComparable then the NodeKeys are compared that way, otherwise the Id are compared
	Compare(Byte, Int32, Byte, Key)	Internal use, compares comparison array bytes
	SetComparisonArrayFromObject	Comparators that use comparison arrays need to override this function. Given a Key object, set the comparisonArray bytes

Extension Methods

	Name	Description
	ToStringDetails(SessionBase, Boolean)	Overloaded. Object details as a string (Defined by Utilities.)
	ToStringDetails(Schema, TypeVersion, Boolean)	Overloaded. Currently only used by Database Manager (Defined by Utilities.)
