AttributeProtocol

public protocol AttributeProtocol

The PangoAttribute structure represents the common portions of all attributes.

Particular types of attributes include this structure as their initial portion. The common portion of the attribute holds the range to which the value in the type-specific part of the attribute applies and should be initialized using [methodPango.Attribute.init]. By default, an attribute will have an all-inclusive range of [0,G_MAXUINT].

The AttributeProtocol protocol exposes the methods and properties of an underlying PangoAttribute instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Attribute. Alternatively, use AttributeRef as a lighweight, unowned reference if you already have an instance you just want to use.
