Syntax

[SerializableAttribute]
public class DataMember : OptimizedPersistable, IEquatable<DataMember>

<SerializableAttribute>
Public Class DataMember
	Inherits OptimizedPersistable
	Implements IEquatable(Of DataMember)

[SerializableAttribute]
public ref class DataMember : public OptimizedPersistable, 
	IEquatable<DataMember^>

[<SerializableAttribute>]
type DataMember =  
    class
        inherit OptimizedPersistable
        interface IEquatable<DataMember>
    end

The DataMember type exposes the following members.

Properties

	Name	Description
	AllowOtherTypesOnSamePage	Objects can be stored more efficiently if all object types on the page share the same type. By default mixed types are allowed. Override this to return false for types that should not share pages with other types. (Overrides OptimizedPersistableAllowOtherTypesOnSamePage.)
	Field	The managed field
	FieldName	Name of managed field
	FieldType	Declared Type of this field
	GetTypeCode	Get the type code for a field
	HasId	Does this field have an Oid?
	IsGuid	true if field is of type Guid
	IsInterface	true if field is if type interface
	WeakIOptimizedPersistableReference	Is this field a VelocityDb.WeakIOptimizedPersistableReference

Methods

	Name	Description
	DecodeToArray	Used by code generator for reading objects.
	DecodeToString	Used by code generator.
	Equals	Determines whether two DataMember instances are equal.
	GetField	Get FieldInfo for the fields VelocityDB cares about
	GetMemberValue	Gets the value of a member within a specified object
	GetTypeFromAnyAssemblyVersion	Load type using GetType(String), and if fails, attempt to load same type from an assembly by assembly name, without specifying assembly version or any other part of the signature
	InitializeAfterRead	Sets up some transient fields (Overrides OptimizedPersistableInitializeAfterRead(SessionBase).)
	isNull	Determines if given bytes represents null
	isShortOidNull	Determines if given bytes represent a null short reference
	ReadMe	Used by code generator (Overrides OptimizedPersistableReadMe(TypeVersion, Byte, Int32, SessionBase, Page, Boolean, Schema, Boolean, ListIOptimizedPersistable, Int32, Int32, Boolean).)
	SetMemberValue	Sets the value of a field within an object
	SetMemberValueWithPossibleConvert	Internal Use and in VelocityDBExtensions
	StringToType	Used by code generator.
	ToString	Override to provide more internal info in browser (Overrides OptimizedPersistableToString.)
	TypeToString	Converts a type to a string the way VelocityDB represents it internally

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.)
