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:

1swfobject.registerObject("clippy.codeblock-0", "9");<aura:attribute name="color" type="docSampleNamespace.Color" />
2

Support for Collections

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

This aura:attribute tag shows the syntax for a List of Apex objects:

1swfobject.registerObject("clippy.codeblock-1", "9");<aura:attribute name="colorPalette" type="List<docSampleNamespace.Color>" />
2

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

1swfobject.registerObject("clippy.codeblock-2", "9");<aura:attribute name="colorPalette" type="docSampleNamespace.Color[]" />
