Overloads

  • 1. int GetAffinityForObject(Type type, string propertyName)
  • 2. int GetAffinityForObject(Type? type, string propertyName, bool beforeChanged)

1. Overload

Attributes: [RequiresUnreferencedCode("Uses reflection over runtime types which is not trim- or AOT-safe.")]

int GetAffinityForObject(Type type, string propertyName)

Summary: Returns a positive integer when this instance supports GetNotificationForProperty for the specified type and propertyName, assuming after-change notifications.

Parameters

NameTypeDescription
typeTypeThe runtime type to query.
propertyNamestringThe 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.")]

int GetAffinityForObject(Type? type, string propertyName, bool beforeChanged)

Summary: Returns a positive integer when this instance supports GetNotificationForProperty for the specified type and propertyName.

Parameters

NameTypeDescription
typeType?The runtime type to query.
propertyNamestringThe property name to query.
beforeChangedboolIf 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.
