/** Advertising and negotiating of content exchange formats.
 *
 * %Gdk::ContentFormats is used to advertise and negotiate the format of
 * content passed between different widgets, windows or applications using
 * for example the clipboard or drag'n'drop.
 *
 * GDK supports content in 2 forms: GType and mime type.
 * Using GTypes is meant only for in-process content transfers. Mime types
 * are meant to be used for data passing both in-process and out-of-process.
 * The details of how data is passed is described in the documentation of
 * the actual implementations.
 *
 * A %Gdk::ContentFormats describes a set of possible formats content can be
 * exchanged in. It is assumed that this set is ordered. GTypes are more
 * important than mime types. Order between different Gtypes or mime types
 * is the order they were added in, most important first. Functions that
 * care about order, such as join(), describe in
 * their documentation how they interpret that order, though in general the
 * order of the first argument is considered the primary order of the result,
 * followed by the order of further arguments.
 *
 * For debugging purposes, the function to_string() exists.
 * It will print a comma-separated list of formats from most important to least
 * important.
 *
 * %Gdk::ContentFormats is an immutable object. After creation, you cannot change
 * the types it represents. Instead, new %Gdk::ContentFormats have to be created.
 * Gdk::ContentFormatsBuilder is meant to help in this endeavor.
 *
 * @see Gdk::Drag, Gdk::Drop, Gdk::Clipboard
