To set the value of an attribute inherited from an interface, redefine the attribute in the component and set its default value. Let’s look at an example with the c:myIntf interface.
1<!--c:myIntf-->
2<aura:interface>
3 <aura:attribute name="myBoolean" type="Boolean" default="true" />
4</aura:interface>This component implements the interface and sets myBoolean to false.
1<!--c:myIntfImpl-->
2<aura:component implements="c:myIntf">
3 <aura:attribute name="myBoolean" type="Boolean" default="false" />
4
5 <p>myBoolean: {!v.myBoolean}</p>
6</aura:component>
