LoadExplicit<E, P>(E, Expression<Func<E, IEnumerable<P>>>)

Explicitly load collection prop from ent (if not already loaded).

public E LoadExplicit<E, P>(E entity, Expression<Func<E, IEnumerable<P>>> prop) where E : class where P : class

Parameters

entity E

prop Expression<Func<E, IEnumerable<P>>>

Returns

E

Type Parameters

E

P

LoadExplicit<E, P>(E, Expression<Func<E, P?>>)

Explicitly load referenced prop from ent (if not already loaded).

public E LoadExplicit<E, P>(E entity, Expression<Func<E, P?>> prop) where E : class where P : class

Parameters

entity E

prop Expression<Func<E, P>>

Returns

E

Type Parameters

E

P

LoadRelated<E>(IQueryable<E>, string)

Load related data associated with the given navigationPropertyPath with the entities selected by the query.

public IQueryable<E> LoadRelated<E>(IQueryable<E> query, string navigationPropertyPath) where E : class

Parameters

query IQueryable<E>

navigationPropertyPath string

Returns

IQueryable<E>

Type Parameters

E

Remarks

navigationPropertyPath is a '.' separated path of navigation property names (all) to be included.

LoadRelated<E, P>(IQueryable<E>, Expression<Func<E, P>>)

Load related data associated with the given navProperty with the entities selected by the query.

public IEagerLoadedQueryable<E, P> LoadRelated<E, P>(IQueryable<E> query, Expression<Func<E, P>> navProperty) where E : class

Parameters

query IQueryable<E>

navProperty Expression<Func<E, P>>

Returns

IEagerLoadedQueryable<E, P>

Type Parameters

E

P

Remarks

This method can be chained to eagerly load multiple navigation properties.

Merge<TEntity>(TEntity)

Merge given ent with any persistent version.

public TEntity Merge<TEntity>(TEntity entity) where TEntity : class, new()

Parameters

entity TEntity

Returns

TEntity

Type Parameters

TEntity

Remarks

A merge is especially usefull when persisting data updated from an input form that typically does not manage any navigation properties (i.e. references to other entities) and thus will leave such properties with their default value (null).

• if the given entity is not persistent yet it gets inserted, else only properties with non-null values are set on the persistent entity.
• Any property changed by the merge operation marks the entity as modified for updating with the store.

Query<TEntity>()

Return a queryable enumeration of ALL entities of E in the store.

public IQueryable<TEntity> Query<TEntity>() where TEntity : class

Returns

IQueryable<TEntity>

Type Parameters

TEntity

Remarks

Any changes to returned entities are beeing tracked (for potential commit with the underlying store).

ResetAll()

Reset all tracked entities to 'untracked'.

public void ResetAll()

ResetChanges()

Reset the change state of all tracked entities to 'unchanged'.

public void ResetChanges()
