Class ScopeTreeSymbolResolver

Namespace

RDCore.SDK.Model.Symbols

Assembly

RDCore.SDK.dll

The compile-time ISymbolResolver: binds an identifier by walking a ScopeTree outward from the scope a lookup originates in — the first scope that declares the name binds it (MS-VBAL §5.2 name binding, RD-VBAL §2.3.1.2). A name declared more than once in a single module or procedure scope resolves as Duplicate(IEnumerable<Symbol>); more than once at the project or global tier resolves as Ambiguous(IEnumerable<Symbol>).

Remarks

A name-resolution service only — the value-binding members throw, matching the intent of a design-time resolver that holds no run-time bindings. Ordering referenced projects and libraries by their .rdproj priority within the global scope, and reporting an ambiguous name as a coded compile-time error rather than an unbound result, are later work.

Methods

GetValue(Symbol)

Gets the IBindingHandle currently associated with the specified Symbol.

public IBindingHandle GetValue(Symbol symbol)

Parameters

symbol Symbol

The Symbol to retrieve the currently associated binding for.

Returns

IBindingHandle

Resolve(string, ScopeKind, Uri)

Resolves name as seen from the scope the symbol at handle belongs to. scope is not consulted — the lookup order is the tree's.

public SymbolResolutionResult Resolve(string name, ScopeKind scope, Uri handle)

Parameters

name string

scope ScopeKind

handle Uri

Returns

SymbolResolutionResult

TryRead(MemoryAddress, out IBindingHandle?)

Gets the IBindingHandle at the specified address in the runtime memory map.

public bool TryRead(MemoryAddress address, out IBindingHandle? value)

Parameters

address MemoryAddress

The memory address to read.

value IBindingHandle

The retrieved binding, if successful.

Returns

bool
