Constructors

MetaType()

Initializes a new instance of the MetaType class.

Properties

Associations

When overridden in a derived class, gets an enumeration of all the associations.

CanInstantiate

When overridden in a derived class, gets whether the underlying type can be instantiated as the result of a query.

DataMembers

When overridden in a derived class, gets an enumeration of all the data members (fields and properties).

DBGeneratedIdentityMember

When overridden in a derived class, gets the member that represents the auto-generated identity column.

DerivedTypes

When overridden in a derived class, gets an enumeration of the immediate derived types in an inheritance hierarchy.

Discriminator

When overridden in a derived class, gets the member that represents the inheritance discriminator column.

HasAnyLoadMethod

When overridden in a derived class, gets a value that indicates whether the current MetaType or any of its bases types has an OnLoaded method.

HasAnyValidateMethod

When overridden in a derived class, gets a value that indicates whether the MetaType or any of its bases types has an OnValidate method.

HasInheritance

When overridden in a derived class, gets a value indicating whether the type is part of a mapped inheritance hierarchy.

HasInheritanceCode

When overridden in a derived class, gets a value indicating whether this type defines an inheritance code.

HasUpdateCheck

When overridden in a derived class, gets a value indicating whether the type has any persistent member that may require a test for optimistic concurrency conflicts.

IdentityMembers

When overridden in a derived class, gets an enumeration of all the data members that define the unique identity of the type.

InheritanceBase

When overridden in a derived class, gets the base meta-type in the inheritance hierarchy.

InheritanceCode

When overridden in a derived class, gets a value indicating whether this type defines an inheritance code.

InheritanceDefault

When overridden in a derived class, gets a value indicating whether this type is used as the default of an inheritance hierarchy.

InheritanceRoot

When overridden in a derived class, gets the root type of the inheritance hierarchy.

InheritanceTypes

When overridden in a derived class, gets a collection of all types that are defined by an inheritance hierarchy.

IsEntity

When overridden in a derived class, gets a value indicating whether the MetaType is an entity type.

IsInheritanceDefault

When overridden in a derived class, gets a value indicating whether this type is used as the default of an inheritance hierarchy.

Model

When overridden in a derived class, gets the MetaModel that contains this MetaType.

Name

When overridden in a derived class, gets the name of the MetaType.

OnLoadedMethod

When overridden in a derived class, gets information about the OnLoaded method contained by this meta-type.

OnValidateMethod

When overridden in a derived class, gets information about the OnValidate method contained by this meta-type.

PersistentDataMembers

When overridden in a derived class, gets a collection of all the persistent data members.

Table

When overridden in a derived class, gets the MetaTable that uses this MetaType for row definition.

Type

When overridden in a derived class, gets the underlying common language runtime (CLR) type.

VersionMember

When overridden in a derived class, gets a row-version or timestamp column for this MetaType.
