Member Function Documentation

void CdsResourceManager::addResources	(	zmm::Ref< CdsItem >	item,
		zmm::Ref< mxml::Element >	element
	)			`[static]`

Adds a resource tag to the item.

Parameters:

	item	Item for which the resources should be added.
	element	Element in the XML to which the resource should be appended.

This function figures out what resources should be added to what files. It looks at the server configuration to find out what it needs. For example, if you want to add another mime/type alias for an existing mime/type, this function would do it. Also, when transcoding will be implemented, the various transcoded streams will be identified here.

Todo:: what if the resource has a different mimetype than the item??

Todo:: who will sync mimetype that is part of the protocl info and that is lying in the resources with the information that is in the resource tags?

Todo:: currently resource is misused for album art
