* Add async read/write hooks to BaseVariableState and AsyncCustomNodeManager
Introduces an end-to-end async path for variable Value-attribute reads
and writes that does not require holding lock(this) while the user
callback executes:
* New AttributeReadResult, AttributeSimpleReadResult and AttributeWriteResult
readonly record structs in NodeState carry the typed result of an async
Value-attribute hook (no ref/out params across await).
* Four new async delegates (NodeValueEventHandlerAsync,
NodeValueSimpleEventHandlerAsync, NodeValueWriteEventHandlerAsync,
NodeValueSimpleWriteEventHandlerAsync) sit alongside the existing sync
hooks.
* NodeState gains virtual ReadAttributeAsync / WriteAttributeAsync methods.
The default implementation wraps the synchronous call in lock(this) so
callers that have not opted into async hooks see bit-identical behaviour.
* BaseVariableState exposes OnReadValueAsync, OnSimpleReadValueAsync,
OnWriteValueAsync and OnSimpleWriteValueAsync slots and overrides the new
virtuals to dispatch to them WITHOUT holding the lock during the await.
On simple-read the framework still applies index range, data encoding and
copy policy; on simple-write the cached value/status/timestamp are
updated under lock after the hook completes.
* AsyncCustomNodeManager.ReadAsync and WriteAsync now await the new
ReadAttributeAsync / WriteAttributeAsync entry points instead of taking
lock(source) around the synchronous call. Existing per-source locking
semantics are preserved by the default async wrappers.
* The fluent INodeBuilder surface gains four new async OnRead/OnWrite
overloads that wire to the new BaseVariableState slots, with the same
ThrowIfSlotOccupied + null-check pattern as the sync overloads.
* Add typed IVariableBuilder<T> fluent surface
Adds typed sub-interfaces and impls so the existing fluent surface
can expose simple Func<T> / Action<T> / Func<CancellationToken,
ValueTask<T>> overloads for variables — without losing the lower-level
Variant-based overloads on INodeBuilder.
* IVariableBuilder<TValue> + VariableBuilder<TValue> derive from
INodeBuilder<BaseVariableState> / NodeBuilder<BaseVariableState>
(NodeBuilder<TState> unsealed).
* Marshalling uses Variant.AsBoxedObject(BoxingBehavior.Legacy) for
reads and Variant(object) for writes; the AOT-unsafe write path is
scoped-suppressed with a TODO pointing at the planned per-type
generated walker.
* INodeManagerBuilder gains Variable<T>(string),
Variable<T>(NodeId), VariableFromTypeId<T>(NodeId),
VariableFromTypeId<T>(NodeId, QualifiedName).
Server library builds clean across all 6 TFMs.
* Add relative-child traversal API on INodeBuilder
Adds INodeBuilder.Child(QualifiedName), Child<TState>(QualifiedName)
and Variable<TValue>(QualifiedName) so source-generated typed
wrappers can walk one segment at a time without re-resolving from
the manager root. Resolution uses NodeState.FindChild and reuses
NodeManagerBuilder.ToVariableBuilder to keep the typed-variable
marshalling story consistent.
Adds 7 NUnit cases (Fluent category) covering the happy path,
type-mismatch, null/missing browse-name, and non-variable
rejection. All 66 fluent tests pass.
* Mix old + new fluent APIs in MinimalBoilerServer demo
BoilerNodeManager.Configure now exercises five wiring styles:
(1) browse-path with the legacy ref-Variant callback
(2) absolute NodeId with the legacy ref-Variant callback
(3) typed Variable<double>(NodeId) + simple Func<double> sync getter
(4) typed Variable<double>(NodeId) + Func<CancellationToken, ValueTask<double>>
async getter — exercises the BaseVariableState.OnReadValueAsync
slot end-to-end through AsyncCustomNodeManager.ReadAsync
(5) NodeFromTypeId with OnNodeAdded lifecycle hook
All five styles compose against the same INodeManagerBuilder, with
the typed and async callbacks pulling in the new IVariableBuilder<T>
surface (committed at e557ecdd9) and the BaseVariableState async
path (committed at 2e2efb4ad).
* Add async-hook tests for BaseVariableState
15 NUnit cases covering the new On{Read,Write}ValueAsync and On
Simple{Read,Write}ValueAsync slots plus the
ReadAttributeAsync/WriteAttributeAsync overrides on
BaseVariableState:
* full async slot routes Value reads/writes
* lock(this) is released around the awaited handler
* simple async slot reapplies cached StatusCode and respects index
ranges (BadIndexRangeInvalid for non-null ranges)
* exceptions and OperationCanceledException from the hook are
caught and surfaced as BadUnexpectedError, mirroring the sync flow
* CancellationToken propagates to the hook
* cache (m_value, m_statusCode, m_timestamp) is updated on success
and skipped on Bad return
* fallback to base sync ReadAttribute/WriteAttribute when no async
slot is set (preserves today's lock(this) semantics)
* non-Value attributes never invoke the async hook
* CurrentRead/CurrentWrite access checks short-circuit before the
hook runs
All 596 State tests pass on net10.0.
* Add round-trip tests for typed IVariableBuilder<T>
Covers the typed Func<T>/Action<T>/Func<...,ValueTask<T>> overloads
on IVariableBuilder<TValue>: each registers the appropriate hook
slot on the underlying BaseDataVariableState, and driving the
variable through ReadAttribute/WriteAttribute (sync) and
ReadAttributeAsync/WriteAttributeAsync (async) reproduces the
typed values the user supplied.
* Add typed model-traversal source generator
Adds FluentBuilderGenerator that walks the design's predefined-instance tree and emits a typed sibling for every NodeManagerBuilder. Each generated wrapper exposes IntelliSense-friendly accessors for child instances, variables (IVariableBuilder<T>) and methods (sync/async OnCall) so wiring sites become builder.Boilers.Boiler__1.LCX001.Measurement.OnRead(...) instead of a stringly typed browse path. The NodeManager template now also emits a Configure(I{Manager}NodeManagerBuilder) partial alongside the existing Configure(INodeManagerBuilder); both partials run, both are optional, and the typed surface is fully AOT-safe (no dynamic, no MakeGenericType, no reflection).
* Add tests for the typed model-traversal source generator
Adds 9 snapshot tests in Tests/Opc.Ua.SourceGeneration.Core.Tests covering the FluentBuilderGenerator's opt-in flag, typed-manager-interface and proxy emission, internal-sealed visibility, lazy child resolution via Context.NamespaceUris.GetIndexOrAppend, IVariableBuilder<TValue> accessors, sync+async OnCall overloads on method wrappers, and the dual Configure(INodeManagerBuilder)/Configure(I{Manager}NodeManagerBuilder) partial wiring in the NodeManager template. Adds 2 end-to-end AOT tests in Tests/Opc.Ua.Aot.Tests that exercise typed-traversal sync read on LCX001/Measurement and typed-traversal async OnCall on Simulation/Halt through the AOT-compiled MinimalBoilerServer fixture.
* Document the typed model-traversal Configure(I{Manager}NodeManagerBuilder) partial
