views_handler_field::add_self_tokens	(	&$	tokens,
		$	item
	)			`[inherited]`

Add any special tokens this field might use for itself.

This method is intended to be overridden by items that generate fields as a list. For example, the field that displays all terms on a node might have tokens for the tid and the term.

By convention, tokens should follow the format of [token-subtoken] where token is the field ID and subtoken is the field. If the field ID is terms, then the tokens might be [terms-tid] and [terms-name].

Reimplemented in views_handler_field_profile_list, views_handler_field_term_node_tid, views_handler_field_upload_fid, and views_handler_field_user_roles.

views_handler_field::advanced_render ( $ values ) [inherited]
