Overloads

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

1. Overload

Attributes: [RequiresUnreferencedCode("The method uses reflection and may not work in AOT environments.")]

public int GetAffinityForObject(Type? type, string propertyName)

View source

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

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

Returns: int -- A positive integer if supported; zero or a negative value otherwise.

2. Overload

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

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.
