IUnaryOperation Interface

Definition

Represents an operation with one operand and a unary operator.

Current usage:

  1. C# unary operation expression
  2. VB unary operation expression

public interface class IUnaryOperation : Microsoft::CodeAnalysis::IOperation
public interface IUnaryOperation : Microsoft.CodeAnalysis.IOperation
type IUnaryOperation = interface
    interface IOperation
Public Interface IUnaryOperation
Implements IOperation
Implements

Remarks

This node is associated with the following operation kinds:

This interface is reserved for implementation by its associated APIs. We reserve the right to change it in the future.

Properties

ChildOperations

An enumerable of child operations for this operation.

(Inherited from IOperation)
Children
Obsolete.

An array of child operations for this operation. Deprecated: please use ChildOperations.

(Inherited from IOperation)
ConstantValue

If the operation is an expression that evaluates to a constant value, HasValue is true and Value is the value of the expression. Otherwise, HasValue is false.

(Inherited from IOperation)
ConstrainedToType

Type parameter which runtime type will be used to resolve virtual invocation of the OperatorMethod, if any. Null if OperatorMethod is resolved statically, or is null.

IsChecked

true if overflow checking is performed for the arithmetic operation.

IsImplicit

Set to True if compiler generated /implicitly computed by compiler code

(Inherited from IOperation)
IsLifted

true if this is a 'lifted' unary operator. When there is an operator that is defined to work on a value type, 'lifted' operators are created to work on the Nullable<T> versions of those value types.

Kind

Identifies the kind of the operation.

(Inherited from IOperation)
Language

The source language of the IOperation. Possible values are CSharp and VisualBasic.

(Inherited from IOperation)
Operand

Operand.

OperatorKind

Kind of unary operation.

OperatorMethod

Operator method used by the operation, null if the operation does not use an operator method.

Parent

IOperation that has this operation as a child. Null for the root.

(Inherited from IOperation)
SemanticModel

Optional semantic model that was used to generate this operation. Non-null for operations generated from source with GetOperation(SyntaxNode, CancellationToken) API and operation callbacks made to analyzers. Null for operations inside a ControlFlowGraph.

(Inherited from IOperation)
Syntax

Syntax that was analyzed to produce the operation.

(Inherited from IOperation)
Type

Result type of the operation, or null if the operation does not produce a result.

(Inherited from IOperation)

Methods

Accept(OperationVisitor) (Inherited from IOperation)
Accept<TArgument,TResult>(OperationVisitor<TArgument,TResult>, TArgument) (Inherited from IOperation)

Extension Methods

Descendants(IOperation)

Returns all the descendant operations of the given operation in evaluation order.

DescendantsAndSelf(IOperation)

Returns all the descendant operations of the given operation including the given operation in evaluation order.
