Lightning Aura Components Developer Guide
jAttribute Access Control
The access attribute on the aura:attribute tag controls whether the attribute can be used
outside of the attribute’s namespace.
Possible values are listed below.
| Access | Description |
|---|---|
| private | Available within the component, app, interface, or event, or method and can’t be
referenced outside the resource. Accessing a private attribute returns undefined unless you reference it from the component in which it’s declared. You can’t access a private attribute from a sub-component that extends the component containing the private attribute. |
| public | Available within your org only. This is the default access value. |
| global | Available in all orgs. |
