Defined in
Type: KVOObservableForProperty
Namespace: ReactiveUI.Reactive

Overloads¶
- 1.
public int GetAffinityForObject(Type type, string propertyName) - 2.
public int GetAffinityForObject(Type? type, string propertyName, bool beforeChanged)
1. Overload¶
Attributes: [RequiresUnreferencedCode("Uses reflection over runtime types which is not trim- or AOT-safe.")]
public int GetAffinityForObject(Type type, string propertyName)
Inherited documentation
These docs were inherited from ICreatesObservableForProperty. The member doesn't override them on this type.
Summary: Returns a positive integer when this instance supports GetNotificationForProperty for the specified type and propertyName, assuming after-change notifications.
Parameters
| Name | Type | Description |
|---|---|---|
type | Type | The runtime type to query. |
propertyName | string | The property name to query. |
Returns: int -- A positive integer if supported; zero or a negative value otherwise.
2. Overload¶
Attributes: [RequiresUnreferencedCode("Uses reflection over runtime types which is not trim- or AOT-safe.")]
public int GetAffinityForObject(Type? type, string propertyName, bool beforeChanged)
Inherited documentation
These docs were inherited from ICreatesObservableForProperty. The member doesn't override them on this type.
Summary: Returns a positive integer when this instance supports GetNotificationForProperty for the specified type and propertyName.
Parameters
| Name | Type | Description |
|---|---|---|
type | Type? | The runtime type to query. |
propertyName | string | The property name to query. |
beforeChanged | bool | If true, indicates the caller requests notifications before the property value changes. If false, indicates after-change notifications. |
Returns: int -- A positive integer if supported; zero or a negative value otherwise.
Remarks
If the method is not supported, return a non-positive integer. When multiple implementations return a positive value, the host selects the highest value.
Implementations should avoid expensive work here; this is typically a hot-path query.
