Interface ILeftRelationBuilder<TEntity>

This interface hosts relation methods for the left side of a relation.

Namespace: Venflow.Modeling.Definitions.Builder

Assembly: Venflow.dll

Syntax

public interface ILeftRelationBuilder<TEntity>
    where TEntity : class, new()

Type Parameters

Name	Description
TEntity	The entity type being configured.

Methods

HasMany<TRelation>()

Configures a relationship where this entity type has a collection that contains instances of the other type in the relationship.

Note that calling this method will explicitly configure this side of the relationship to use no navigation property, even if such a property exists on the entity type. If the navigation property is to be used, then it must be specified.

After calling this method, you should chain a call to WithOne(Expression<Func<TRelation, TEntity>>) to fully configure the relationship. Calling just this method without the chained call will not produce a valid relationship.

Declaration

IRequiredSingleRightRelationBuilder<TEntity, TRelation> HasMany<TRelation>()
    where TRelation : class

Returns

Type	Description
IRequiredSingleRightRelationBuilder<TEntity, TRelation>	An object that can be used to configure the relationship.

Type Parameters

Name	Description
TRelation	The entity type that this relationship targets.

HasMany<TRelation>(Expression<Func<TEntity, IList<TRelation>>>)

Configures a relationship where this entity type has a collection that contains instances of the other type in the relationship.

Note that calling this method with no parameters will explicitly configure this side of the relationship to use no navigation property, even if such a property exists on the entity type. If the navigation property is to be used, then it must be specified.

After calling this method, you should chain a call to WithOne() to fully configure the relationship. Calling just this method without the chained call will not produce a valid relationship.

Declaration

INotRequiredSingleRightRelationBuilder<TEntity, TRelation> HasMany<TRelation>(Expression<Func<TEntity, IList<TRelation>>> navigationProperty)
    where TRelation : class

Parameters

Type	Name	Description
Expression<Func<TEntity, IList<TRelation>>>	navigationProperty

Returns

Type	Description
INotRequiredSingleRightRelationBuilder<TEntity, TRelation>	An object that can be used to configure the relationship.

Type Parameters

Name	Description
TRelation	The entity type that this relationship targets.

HasOne<TRelation>()

Configures a relationship where this entity type has a reference that points to a single instance of the other type in the relationship.

Note that calling this method will explicitly configure this side of the relationship to use no navigation property, even if such a property exists on the entity type. If the navigation property is to be used, then it must be specified.

After calling this method, you should chain a call to WithMany(Expression<Func<TRelation, IList<TEntity>>>) or WithOne(Expression<Func<TRelation, TEntity>>) to fully configure the relationship. Calling just this method without the chained call will not produce a valid relationship.

Declaration

IRequiredMultiRightRelationBuilder<TEntity, TRelation> HasOne<TRelation>()
    where TRelation : class

Returns

Type	Description
IRequiredMultiRightRelationBuilder<TEntity, TRelation>	An object that can be used to configure the relationship.

Type Parameters

Name	Description
TRelation	The entity type that this relationship targets.

HasOne<TRelation>(Expression<Func<TEntity, TRelation>>)

Configures a relationship where this entity type has a reference that points to a single instance of the other type in the relationship.

Note that calling this method with no parameters will explicitly configure this side of the relationship to use no navigation property, even if such a property exists on the entity type. If the navigation property is to be used, then it must be specified.

After calling this method, you should chain a call to WithMany() or WithOne() to fully configure the relationship. Calling just this method without the chained call will not produce a valid relationship.

Declaration

INotRequiredMultiRightRelationBuilder<TEntity, TRelation> HasOne<TRelation>(Expression<Func<TEntity, TRelation>> navigationProperty)
    where TRelation : class

Parameters

Type	Name	Description
Expression<Func<TEntity, TRelation>>	navigationProperty	A lambda expression representing the reference navigation property on this entity type that represents the relationship (post => post.Blog). If no property is specified, the relationship will be configured without a navigation property on this end.

Returns

Type	Description
INotRequiredMultiRightRelationBuilder<TEntity, TRelation>	An object that can be used to configure the relationship.

Type Parameters

Name	Description
TRelation	The entity type that this relationship targets.
