ParamSpecBooleanProtocol
public protocol ParamSpecBooleanProtocol : ParamSpecProtocol
A GParamSpec
derived structure that contains the meta data for boolean properties.
The ParamSpecBooleanProtocol
protocol exposes the methods and properties of an underlying GParamSpecBoolean
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 ParamSpecBoolean
.
Alternatively, use ParamSpecBooleanRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
