Detailed Description
Shared cache mapping host UUID strings to whimsical display names.
Avoids repeated list-hosts requests by centralising the UUID → name mapping. All client models that need to render host names hold a pointer to the single instance owned by the controller.
If a UUID is not present in the cache, display_name_for() returns the first 8 characters of the UUID as a short-ID fallback.
Member Function Documentation
◆ display_name_for()
| QString display_name_for | ( | const QString & | uuid | ) | const |
Returns the display name for the given UUID string.
Falls back to the first 8 characters of the UUID when the cache has no entry (e.g., the host was registered after the last refresh).
◆ populate_from()
| void populate_from | ( | const std::vector< compute::domain::host > & | hosts | ) |
Populates (or updates) the cache from a list of hosts.
Existing entries are overwritten if the host appears in hosts. Entries for hosts not present in hosts are kept (no eviction).
