Interface IQueryRegistry

Namespace

NextORM.Core

Assembly

nextorm.core.dll

Registry of the queries, outer references and plan-equality comparers that make up a query scope.

public interface IQueryRegistry

Extension Methods

EntityBuilderExtensions.AsEntityBuilder<T>(object?)

Remarks

It coordinates the plan cache (query registrations, outer references and comparer instances) rather than building queries, so it is deliberately named IQueryRegistry to avoid the collision with IQueryProvider.

Properties

OuterReferences

The outer expressions captured by the current query, or null when there are none.

IReadOnlyList<Expression>? OuterReferences { get; }

Property Value

IReadOnlyList<Expression>

ReferencedQueries

The queries referenced by the current query, indexed by the reference markers in its expressions.

IReadOnlyList<QueryCommand> ReferencedQueries { get; }

Property Value

IReadOnlyList<QueryCommand>

Methods

AddCommand(QueryCommand)

Registers cmd as a referenced query and returns its zero-based index within ReferencedQueries.

int AddCommand(QueryCommand cmd)

Parameters

cmd QueryCommand

The command to reference.

Returns

int

AddOuterReference(Expression)

Registers an outer expression and returns its zero-based index within OuterReferences.

int AddOuterReference(Expression node)

Parameters

node Expression

The outer expression to capture.

Returns

int

GetFromExpressionPlanEqualityComparer()
