Custom Apex Class Types

An attribute can have a type corresponding to an Apex class. For example, this is an attribute for a Color Apex class:

1<aura:attribute name="color" type="docSampleNamespace.Color" />

Using Arrays

If an attribute can contain more than one element, use an array.

This aura:attribute tag shows the syntax for an array of Apex objects:

1<aura:attribute name="colorPalette" type="docSampleNamespace.Color[]" />

Make your Apex class methods, getter and setter methods, available to your components by annotating them with @AuraEnabled.
