Visit(SqlExpression, Boolean, Boolean)

Source:

SqlNullabilityProcessor.cs

Visits a SqlExpression and computes its nullability.

protected virtual Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression? Visit (Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression? sqlExpression, bool allowOptimizedExpansion, out bool nullable);

abstract member Visit : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression
override this.Visit : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression * bool * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression

Protected Overridable Function Visit (sqlExpression As SqlExpression, allowOptimizedExpansion As Boolean, ByRef nullable As Boolean) As SqlExpression

Parameters

sqlExpression

SqlExpression

A sql expression to visit.

allowOptimizedExpansion

Boolean

A bool value indicating if optimized expansion which considers null value as false value is allowed.

nullable

Boolean

A bool value indicating whether the sql expression is nullable.

Returns

SqlExpression

An optimized sql expression.

Visit(SelectExpression, Boolean)

Source:

SqlNullabilityProcessor.cs

Visits a SelectExpression.

protected virtual Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression Visit (Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression selectExpression, bool visitProjection);

abstract member Visit : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression
override this.Visit : Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression * bool -> Microsoft.EntityFrameworkCore.Query.SqlExpressions.SelectExpression

Protected Overridable Function Visit (selectExpression As SelectExpression, visitProjection As Boolean) As SelectExpression

Parameters

selectExpression

SelectExpression

A select expression to visit.

visitProjection

Boolean

Allows skipping visiting the projection, for when it will be visited outside.

Returns

SelectExpression

An optimized select expression.

Visit(SqlExpression, Boolean)

Source:
