## RBRandomPlayOrder RBRandomPlayOrder — base class for weighted random play orders |

## Types and Values

struct | RBRandomPlayOrder
struct | RBRandomPlayOrderClass

## Object Hierarchy

        GObject
        ╰── RBPlayOrder
            ╰── RBRandomPlayOrder

## Description

Subclasses only need to override `get_entry_weight()` to return the right weight for a given entry.

This class also delays committing any changes until the user moves to the next or previous song. So if the user changes the entry-view to contain different songs, but changes it back before the current song finishes, they will not see any changes to their history of played songs.
