IObservable<(bool ShouldEmit, TValue Value)> CreateDirectSetObservable<TTarget, TValue, TObs>(TTarget? target, IObservable<TObs> observedChanged, Expression viewExpression, Func<object?, object?[]?, object?> getter, Action<object?, object?, object?[]?> setter, Func<Type?, Type?, Func<object?, object?, object?[]?, object?>?> getSetConverter) where TTarget : class
Summary: Creates an observable for direct member binding (no intermediate chain).
Type parameters
| Name | Description |
|---|---|
TTarget | The target object type. |
TValue | The property value type. |
TObs | The observed change type. |
Parameters
| Name | Type | Description |
|---|---|---|
target | TTarget? | The target object instance. |
observedChanged | IObservable | The observable tracking property changes. |
viewExpression | Expression | The view expression. |
getter | Func | The compiled getter. |
setter | Action | The compiled setter. |
getSetConverter | Func | Optional set-method converter resolver. |
Returns: IObservable<(bool ShouldEmit, TValue Value)> -- An observable that emits tuples of (shouldEmit, value) when the property changes.
Remarks
Direct set observables are optimized for simple property bindings without intermediate
object navigation. They don't need to track host changes.
