Class HudMemberAccessor

One resolved hop of a HUD binding chain: a field, property or method located on a type once, then read many times.

Syntax

public sealed class HudMemberAccessor

Remarks

Resolution happens at compile time and the arguments are converted once, so a per-frame read is a reflection invoke on cached metadata rather than a fresh lookup.

Properties

MemberName

The member's name, for diagnostics.

Declaration

Property Value

Type	Description

ResultType

The static type this step produces, used to classify the value and pick a representation.

TryResolve(Type, IHudMemberStep, Func<string, Type>, out HudMemberAccessor, out string)

Resolves one step against the type it is evaluated on.
