Class ExpressionBindings

Namespace

RDCore.SDK.Semantics.Binding

Assembly

RDCore.SDK.dll

What the expressions of a tree bind to, recorded as the static semantics evaluate them: an operand before the expression that has it.

public sealed class ExpressionBindings

Inheritance

object

ExpressionBindings

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.ReferenceEquals(object, object)

object.ToString()

Remarks

The bindings are those of the expressions the static semantics evaluate: an expression after an operand that is a compile error is not evaluated, and is not bound. Like the evaluation it records, a recorder is for one binding at a time: it is not thread-safe.

Properties

Bound

What each expression bound to, by its Identity.

public IReadOnlyDictionary<SyntaxNodeId, BoundExpression> Bound { get; }

Property Value

IReadOnlyDictionary<SyntaxNodeId, BoundExpression>

Frame

The layout of the activations of the procedure the expressions are written in, which binds its parameters and variables to their slots; null when the expressions are bound outside a procedure, and no variable is bound to a slot.

public FrameLayout? Frame { get; init; }

Property Value

FrameLayout

this[SyntaxNodeId]

What the expression with this Identity bound to, if it was bound.

public BoundExpression? this[SyntaxNodeId node] { get; }

Parameters

node SyntaxNodeId

Property Value

BoundExpression

Methods

NodeOf(ExpressionNode)

The bound tree of an expression that was bound (BoundNode); null for one that was not.

public BoundNode? NodeOf(ExpressionNode expression)

Parameters

expression ExpressionNode

The expression.

Returns

BoundNode
