Methods

ShouldConvertToInlineQueryRoot(Expression)

Indicates that a Expression can be converted to a InlineQueryRootExpression; the latter will end up in TranslateInlineQueryRoot(InlineQueryRootExpression) for translation to a SQL ValuesExpression.
ShouldConvertToInlineQueryRoot(Expression)

Determines whether a Expression should be converted to a InlineQueryRootExpression.

(Inherited from QueryRootProcessor)
ShouldConvertToInlineQueryRoot(NewArrayExpression)

Indicates that a ConstantExpression can be converted to a InlineQueryRootExpression; the latter will end up in VisitInlineQueryRoot(InlineQueryRootExpression) for translation to a SQL ValuesExpression.
ShouldConvertToInlineQueryRoot(NewArrayExpression)

Determines whether a ConstantExpression should be converted to a InlineQueryRootExpression. This handles cases inline expressions whose elements are all constants.

(Inherited from QueryRootProcessor)
ShouldConvertToParameterQueryRoot(ParameterExpression)

Indicates that a ParameterExpression can be converted to a ParameterQueryRootExpression; the latter will end up in TranslatePrimitiveCollection(SqlExpression, IProperty, String) for translation to a provider-specific SQL expansion mechanism, e.g. OPENJSON on SQL Server.
VisitExtension(Expression)

Visits the children of the extension expression.
VisitMethodCall(MethodCallExpression)

Visits the children of the MethodCallExpression.
