A KeyedUpdatableQueue is a refinement of the UpdatableQueue concept. It requires that models order the contained values by their keys, to which values are mapped via a read/write key map.
| Q | is a type that models KeyedUpdatableQueue. |
| T | is the value type of Q. |
| Member | Description |
| key_type | The type of keys that are associated with values |
| key_map | The key property map type. This type must model Read/Write Property Map. |
| key_map keys() const | Returns the key map |
