ICoalesceAssignmentOperation Interface

Definition

Namespace:

Microsoft.CodeAnalysis.Operations

Assembly:

Microsoft.CodeAnalysis.dll

Package:

Microsoft.CodeAnalysis.Common v4.9.2

Source:

Operations.Generated.cs

Represents a coalesce assignment operation with a target and a conditionally-evaluated value:

1. Target is evaluated for null. If it is null, Value is evaluated and assigned to target
2. Value is conditionally evaluated if Target is null, and the result is assigned into Target

The result of the entire expression is Target, which is only evaluated once.

Current usage:

1. C# null-coalescing assignment operation Target ??= Value

Remarks

This node is associated with the following operation kinds:

• CoalesceAssignment

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)
IsImplicit	Set to True if compiler generated /implicitly computed by compiler code (Inherited from IOperation)
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)
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)
Target	Target of the assignment. (Inherited from IAssignmentOperation)
Type	Result type of the operation, or null if the operation does not produce a result. (Inherited from IOperation)
Value	Value to be assigned to the target of the assignment. (Inherited from IAssignmentOperation)

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.
