Methods

GetMetadata(AvaloniaObject)

public DirectPropertyMetadata<TValue> GetMetadata(AvaloniaObject owner)

Parameters

owner AvaloniaObject

The object for which to retrieve metadata.

Returns

DirectPropertyMetadata<TValue>

GetMetadata(Type)

Gets the AvaloniaPropertyMetadata which applies to this property when it is used with the specified type.

public DirectPropertyMetadata<TValue> GetMetadata(Type type)

Parameters

type Type

The type for which to retrieve metadata.

Returns

DirectPropertyMetadata<TValue>

Remarks

For performance, prefer the GetMetadata(AvaloniaObject) overload when possible.

GetUnsetValue(AvaloniaObject)
