Constructors
| JsonScalarExpression(ColumnExpression, IProperty, IReadOnlyList<PathSegment>, Boolean) |
Creates a new instance of the JsonScalarExpression class. |
| JsonScalarExpression(SqlExpression, IReadOnlyList<PathSegment>, Type, RelationalTypeMapping, Boolean) |
Creates a new instance of the JsonScalarExpression class. |
Properties
| IsNullable |
The value indicating whether the expression is nullable. |
| Json |
The expression containing the JSON value. |
| JsonColumn |
The column containg JSON value. |
| NodeType | (Inherited from SqlExpression) |
| Path |
The list of path segments leading to the scalar from the root of the JSON stored in the column. |
| Type | (Inherited from SqlExpression) |
| TypeMapping |
The RelationalTypeMapping associated with this expression. (Inherited from SqlExpression) |
Methods
| Equals(Object) | System.Linq.Expressions.Expression.Equals(System.Object) |
| GetHashCode() | System.Linq.Expressions.Expression.GetHashCode |
| Print(ExpressionPrinter) |
Creates a printable string representation of the given expression using ExpressionPrinter. |
| Quote() | System.Linq.Expressions.Expression.Quote |
| Quote() |
Quotes the expression; that is, returns an expression that, when evaluated, would construct an expression identical to this one. Used to generate code for precompiled queries, which reconstructs this expression. (Inherited from SqlExpression) |
| Update(ColumnExpression) |
Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression. |
| Update(SqlExpression) |
Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression. |
| VisitChildren(ExpressionVisitor) | Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible. |
Explicit Interface Implementations
| IPrintableExpression.Print(ExpressionPrinter) |
Creates a printable string representation of the given expression using ExpressionPrinter. (Inherited from SqlExpression) |
