Syntax

public abstract class DirectPropertyBase<TValue> : AvaloniaProperty<TValue>, 
    IEquatable<AvaloniaProperty>, IPropertyInfo

Remarks

Whereas DirectProperty<TOwner, TValue> is typed on the owner type, this base class provides a non-owner-typed interface to a direct poperty.

Type Parameters

Name Description
TValue The type of the property's value.
