C# Класс Breeze.PocoMetadata.EntityDescriptor

Describes the metadata for a set of entities. The PocoMetadataBuilder calls methods on this class to determine how to generate metadata for the entities. Extend this class to adapt to your data model.

Открытые методы

Метод	Описание
GetAutoGeneratedKeyType ( Type type ) : string	Get the autoGeneratedKeyType value for the given type. Should be defined even if the actual key property is on a base type.
GetDataPropertyType ( Type type, PropertyInfo propertyInfo ) : Type	Change the type of the given data property in the metadata. For example, a custom wrapper type on the server may be unwrapped on the client, and the metadata reflects this.
GetForeignKeyName ( Type type, PropertyInfo propertyInfo ) : string	Get the foreign key for the given scalar navigation property. This is another property on the same entity that establishes the foreign key relationship.
GetMissingFKHandling ( Type type, PropertyInfo propertyInfo ) : MissingKeyHandling	Determine the generator behaves if a foreign key data property cannot be found for the given navigation property.
GetMissingPKHandling ( Type type ) : MissingKeyHandling	Determine the generator behaves if a primary key is missing on an entity.
GetResourceName ( Type type ) : string	Get the server resource name (endpoint) for the given type. E.g. for entity type Product, it might be "Products". This value is used by Breeze client when composing a query URL for an entity.
Include ( Type type ) : bool	Filter types from metadata generation.
IsComplexType ( Type type ) : bool	Determine if the given type is a "Complex Type" instead of an "Entity". Complex Types are sometimes called component types or embedded types, because they are part of the parent entity instead of being related by foreign keys.
IsKeyProperty ( Type type, PropertyInfo propertyInfo ) : bool	Determine if the property is part of the entity key.
IsVersionProperty ( Type type, PropertyInfo propertyInfo ) : bool	Determine if the property is a version property used for optimistic concurrency control.
Pluralize ( string s ) : string	Lame pluralizer. Assumes we just need to add a suffix. Consider using System.Data.Entity.Design.PluralizationServices.PluralizationService.
Replace ( Type type, IEnumerable types ) : Type	Replace the given type wherever it appears in the metadata. Can be used to replace an interface with a class.

Описание методов

GetAutoGeneratedKeyType() публичный Метод

Get the autoGeneratedKeyType value for the given type. Should be defined even if the actual key property is on a base type.

public GetAutoGeneratedKeyType ( Type type ) : string
type	System.Type	Entity type for which metadata is being generated
Результат	string

GetDataPropertyType() публичный Метод

Change the type of the given data property in the metadata. For example, a custom wrapper type on the server may be unwrapped on the client, and the metadata reflects this.

public GetDataPropertyType ( Type type, PropertyInfo propertyInfo ) : Type
type	System.Type	Entity type for which metadata is being generated
propertyInfo	System.Reflection.PropertyInfo	Property being considered
Результат	System.Type

GetForeignKeyName() публичный Метод

Get the foreign key for the given scalar navigation property. This is another property on the same entity that establishes the foreign key relationship.

public GetForeignKeyName ( Type type, PropertyInfo propertyInfo ) : string
type	System.Type	Entity type for which metadata is being generated
propertyInfo	System.Reflection.PropertyInfo	Scalar navigation/association property
