RelationalTypeMappingSource Class

Definition

Namespace:

Microsoft.EntityFrameworkCore.Storage

Assembly:

Microsoft.EntityFrameworkCore.Relational.dll

Package:

Microsoft.EntityFrameworkCore.Relational v8.0.0

The base class for relational type mapping source. Relational providers should derive from this class and override Microsoft.EntityFrameworkCore.Storage.RelationalTypeMappingSource.FindMapping(Microsoft.EntityFrameworkCore.Storage.RelationalTypeMappingInfo@)

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

Remarks

The service lifetime is Singleton. This means a single instance is used by many DbContext instances. The implementation must be thread-safe. This service cannot depend on services registered as Scoped.

See Implementation of database providers and extensions for more information and examples.

Constructors

RelationalTypeMappingSource(TypeMappingSourceDependencies, RelationalTypeMappingSourceDependencies)

Initializes a new instance of this class.

Properties

Dependencies	Dependencies for this service. (Inherited from TypeMappingSourceBase)
RelationalDependencies	Relational provider-specific dependencies for this service.

Methods

FindCollectionMapping(RelationalTypeMappingInfo, Type, Type, CoreTypeMapping)	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
FindMapping(IElementType)	Finds the type mapping for the given IElementType.
FindMapping(IProperty)	Finds the type mapping for a given IProperty.
FindMapping(MemberInfo)	Finds the type mapping for a given MemberInfo representing a field or a property of a CLR type.
FindMapping(RelationalTypeMappingInfo)	Overridden by relational database providers to find a type mapping for the given info.
FindMapping(String)	Finds the type mapping for a given database type name.
FindMapping(Type)	Finds the type mapping for a given Type.
FindMapping(Type, IModel)	Finds the type mapping for a given Type, taking pre-convention configuration into the account. (Inherited from TypeMappingSourceBase)
FindMapping(Type, IModel, CoreTypeMapping)	Finds the type mapping for a given Type, taking pre-convention configuration into the account.
FindMapping(Type, String, Boolean, Nullable<Boolean>, Nullable<Int32>, Nullable<Boolean>, Nullable<Boolean>, Nullable<Int32>, Nullable<Int32>)	Finds the type mapping for a given Type and additional facets.
FindMapping(TypeMappingInfo)	Call Microsoft.EntityFrameworkCore.Storage.RelationalTypeMappingSource.FindMapping(Microsoft.EntityFrameworkCore.Storage.RelationalTypeMappingInfo@) instead
ParseStoreTypeName(String, Nullable<Boolean>, Nullable<Int32>, Nullable<Int32>, Nullable<Int32>)	Parses a provider-specific store type name, extracting the standard facets (e.g. size, precision) and returns the base store type name (without any facets).
TryFindJsonCollectionMapping(TypeMappingInfo, Type, Type, CoreTypeMapping, ValueComparer, JsonValueReaderWriter)	Attempts to find a JSON-based type mapping for a collection of primitive types. (Inherited from TypeMappingSourceBase)
ValidateMapping(CoreTypeMapping, IProperty)	Called after a mapping has been found so that it can be validated for the given property. (Inherited from TypeMappingSourceBase)

Explicit Interface Implementations

IRelationalTypeMappingSource.FindMapping(IProperty)

Finds the type mapping for a given IProperty.

Extension Methods

GetMapping(IRelationalTypeMappingSource, IProperty)	Gets the relational database type for a given property, throwing if no mapping is found.
GetMapping(IRelationalTypeMappingSource, String)	Gets the mapping that represents the given database type, throwing if no mapping is found.
GetMapping(IRelationalTypeMappingSource, Type)	Gets the relational database type for a given .NET type, throwing if no mapping is found.
GetMapping(IRelationalTypeMappingSource, Type, IModel)	Gets the relational database type for a given .NET type, throwing if no mapping is found.
GetMappingForValue(IRelationalTypeMappingSource, Object)	Gets the relational database type for a given object, throwing if no mapping is found.
GetMappingForValue(IRelationalTypeMappingSource, Object, IModel)	Gets the relational database type for a given object, throwing if no mapping is found.
