ICoalesceOperation Interface

Definition

Namespace:

Microsoft.CodeAnalysis.Operations

Assembly:

Microsoft.CodeAnalysis.dll

Package:

Microsoft.CodeAnalysis.Common v4.9.2

Source:

Operations.Generated.cs

Represents a coalesce operation with two operands:

1. Value, which is the first operand that is unconditionally evaluated and is the result of the operation if non null
2. WhenNull, which is the second operand that is conditionally evaluated and is the result of the operation if Value is null

Current usage:

1. C# null-coalescing expression Value ?? WhenNull
2. VB binary conditional expression If(Value, WhenNull)

Remarks

This node is associated with the following operation kinds:

• Coalesce

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)
Type	Result type of the operation, or null if the operation does not produce a result. (Inherited from IOperation)
Value	Operation to be unconditionally evaluated.
ValueConversion	Conversion associated with Value when it is not null/Nothing. Identity if result type of the operation is the same as type of Value. Otherwise, if type of Value is nullable, then conversion is applied to an unwrapped Value, otherwise to the Value itself.
WhenNull	Operation to be conditionally evaluated if Value evaluates to null/Nothing.

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.
