CoreTypeMapping Class

Definition

Namespace:

Microsoft.EntityFrameworkCore.Storage

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v8.0.0

Represents the mapping between a .NET type and a database type.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Remarks

Constructors

CoreTypeMapping(CoreTypeMapping+CoreTypeMappingParameters)

Initializes a new instance of the CoreTypeMapping class.

Properties

ClrType	Gets the .NET type used in the EF model.
Comparer	A ValueComparer adds custom value snapshotting and comparison for CLR types that cannot be compared with Equals(Object, Object) and/or need a deep copy when taking a snapshot.
Converter	Converts types to and from the store whenever this mapping is used. May be null if no conversion is needed.
ElementTypeMapping	If this type mapping represents a primitive collection, this holds the element's type mapping.
JsonValueReaderWriter	Handles reading and writing JSON values for instances of the mapped type.
KeyComparer	A ValueComparer adds custom value comparison for use when comparing key values to each other. For example, when comparing a PK to and FK.
Parameters	Returns the parameters used to create this type mapping.
ProviderValueComparer	A ValueComparer for the provider CLR type values.
ValueGeneratorFactory	Obsolete. An optional factory for creating a specific ValueGenerator to use with this mapping.

Methods

Clone(CoreTypeMapping+CoreTypeMappingParameters)	Creates a copy of this mapping.
Clone(Nullable<TypeMappingInfo>, Type, ValueConverter, ValueComparer, ValueComparer, ValueComparer, CoreTypeMapping, JsonValueReaderWriter)	Clones the type mapping to update any parameter if needed.
GenerateCodeLiteral(Object)	Creates a an expression tree that can be used to generate code for the literal value. Currently, only very basic expressions such as constructor calls and factory methods taking simple constants are supported.
WithComposedConverter(ValueConverter, ValueComparer, ValueComparer, CoreTypeMapping, JsonValueReaderWriter)	Returns a new copy of this type mapping with the given ValueConverter added.
