public int GetAffinityForObject(Type type, string propertyName, bool beforeChanged = false)
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 = false | 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.
