8.4 Packet Template Inheritance

You can create a packet/struct template that inherits field layouts defined in another template.

The created template has all the fields defined in the inherited templates plus its own fields. All

fields must have unique names.

Note: The parser adds the fields defined in the created packet template after it adds fields from

the inherited templates.

You can change the default field values of the inherited fields.

8.4.1 Packet Template Single Inheritance

A new template inherits the field layouts from another template using an ancestor list.

Examples

Packet MY_DataPacket : DataPacket

{

# Example of a field with variable length having a default value.

Data : * = { 00 00 00 01 }

}

# More examples of template inheritance

const LMP = 0

const LMP_SET_LINK_FUNC = 1

}

Packet LMPCommon : USB3Common # Derive a template from a USB3Common

# template.

{
