Remarks

The grammar splits this construct across two alternatives to stay SLL: TypeOf <expr> parses as its own typeofexpr alternative, and the trailing Is <type> as an ordinary IS relational operator around it. The parse listener recognizes that pairing (a typeofexpr as the left operand of an IS relational op) and builds this node for both together, instead of misreading the construct as a plain object-identity Is comparison.

public TypeOfIsExpressionNode(SyntaxNodeId Identity, SourceLocation Location, ExpressionNode Operand, ExpressionNode TypeExpression)

Parameters

Identity SyntaxNodeId

A unique identifier for this specific syntax node.

Location SourceLocation

The document location (Uri+Range) of the bound expression.

Operand ExpressionNode

The expression whose run-time type is being tested.

TypeExpression ExpressionNode

The expression naming the type being tested against.
