FindMapping(IElementType)

Finds the type mapping for a given IElementType.

public abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (Microsoft.EntityFrameworkCore.Metadata.IElementType elementType);

abstract member FindMapping : Microsoft.EntityFrameworkCore.Metadata.IElementType -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public MustOverride Function FindMapping (elementType As IElementType) As CoreTypeMapping

Parameters

elementType

IElementType

The collection element.

Returns

CoreTypeMapping

The type mapping, or null if none was found.

Implements

FindMapping(IElementType)

FindMapping(IProperty)

Finds the type mapping for a given IProperty.

public abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (Microsoft.EntityFrameworkCore.Metadata.IProperty property);

abstract member FindMapping : Microsoft.EntityFrameworkCore.Metadata.IProperty -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public MustOverride Function FindMapping (property As IProperty) As CoreTypeMapping

Parameters

property

IProperty

The property.

Returns

CoreTypeMapping

The type mapping, or null if none was found.

Implements

FindMapping(IProperty)

Remarks

Note: providers should typically not need to override this method.

FindMapping(TypeMappingInfo)

Overridden by database providers to find a type mapping for the given info.

protected virtual Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (in Microsoft.EntityFrameworkCore.Storage.TypeMappingInfo? mappingInfo);

abstract member FindMapping : TypeMappingInfo -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping
override this.FindMapping : TypeMappingInfo -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Protected Overridable Function FindMapping (mappingInfo As TypeMappingInfo) As CoreTypeMapping

Parameters

mappingInfo

TypeMappingInfo

The mapping info to use to create the mapping.

Returns

CoreTypeMapping

The type mapping, or null if none could be found.

Remarks

The mapping info is populated with as much information about the required type mapping as is available. Use all the information necessary to create the best mapping. Return null if no mapping is available.

FindMapping(MemberInfo)

Finds the type mapping for a given MemberInfo representing a field or a property of a CLR type.

public abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (System.Reflection.MemberInfo member);

abstract member FindMapping : System.Reflection.MemberInfo -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public MustOverride Function FindMapping (member As MemberInfo) As CoreTypeMapping

Parameters

member

MemberInfo

The field or property.

Returns

CoreTypeMapping

The type mapping, or null if none was found.

Implements

FindMapping(MemberInfo)

Remarks

Note: Only call this method if there is no IProperty available, otherwise call FindMapping(IProperty)

Note: providers should typically not need to override this method.

FindMapping(Type)

Finds the type mapping for a given Type.

public abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (Type type);

abstract member FindMapping : Type -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public MustOverride Function FindMapping (type As Type) As CoreTypeMapping

Parameters

type

Type

The CLR type.

Returns

CoreTypeMapping

The type mapping, or null if none was found.

Implements

FindMapping(Type)

Remarks

Note: Only call this method if there is no IProperty or IModel available, otherwise call FindMapping(IProperty) or FindMapping(Type, IModel, CoreTypeMapping)

FindMapping(Type, IModel, CoreTypeMapping)

Finds the type mapping for a given Type, taking pre-convention configuration into the account.

public abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? FindMapping (Type type, Microsoft.EntityFrameworkCore.Metadata.IModel model, Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? elementMapping = default);

abstract member FindMapping : Type * Microsoft.EntityFrameworkCore.Metadata.IModel * Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public MustOverride Function FindMapping (type As Type, model As IModel, Optional elementMapping As CoreTypeMapping = Nothing) As CoreTypeMapping

Parameters

type

Type

The CLR type.

model

IModel

The model.

elementMapping

CoreTypeMapping

The element mapping to use, if known.

Returns

CoreTypeMapping

The type mapping, or null if none was found.

Implements

FindMapping(Type, IModel, CoreTypeMapping)

Remarks

Note: Only call this method if there is no IProperty, otherwise call FindMapping(IProperty).
