Class UnionSource<TEntity>

Namespace

eQuantic.Core.Data.Query

Assembly

eQuantic.Core.Data.dll

A union branch under composition: the entity source, its filters, and finally its projection.

public sealed class UnionSource<TEntity> where TEntity : class

Type Parameters

TEntity

The entity type the branch reads.

Inheritance

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

object.ToString()

Methods

IgnoringQueryFilters()

Opts this branch out of the entity's global query filter.

public UnionSource<TEntity> IgnoringQueryFilters()

Returns

UnionSource<TEntity>

Select<TResult>(Expression<Func<TEntity, TResult>>)

Projects the branch into the union's common shape. Each projected member must be an entity member or a constant (a per-branch tag); derived values are computed after materialization.

public UnionBranch<TResult> Select<TResult>(Expression<Func<TEntity, TResult>> projection)

Parameters

projection Expression<Func<TEntity, TResult>>

The projection.

Returns

UnionBranch<TResult>

Type Parameters

TResult

The common result shape (anonymous or member-init).

Where(Expression<Func<TEntity, bool>>)

Filters the branch — every call ANDs another predicate. The filter applies before the union.

public UnionSource<TEntity> Where(Expression<Func<TEntity, bool>> filter)

Parameters

filter Expression<Func<TEntity, bool>>

The predicate.

Returns

UnionSource<TEntity>
