CommandMap contains a method that will auto-complete commands
appropriately. Before the first space, it searches for commands of which
the sender has permission. After the first space, it delegates to the
individual command.
Vanilla commands contain implementations to mimic vanilla
implementation. Exception would be give, that allows for name matching;
a feature we already allowed as part of the command is now supported for
auto-complete as well.
Plugin commands can get a tab completer set to delegate the completion
for. If no tab completer is set, it can check the executor to see if it
implements the tab completion interface. It will also attempt to chain
calls if null gets returned from these interfaces. Plugins also
implement the new TabCompleter interface, to add ease-of-use for plugin
developers, similar to the onCommand() method.
The default command implementation simply searches for player names.
To help facilitate command completion, a utility class was added with
two functions. One checks two strings, to see if the specified string
starts with (ignoring case) the second. The other method uses the first
to selectively copy elements from one collection to another.
When an exception occurs, the version of the plugin is not included.
Having this information would be beneficial to plugin authors performing
debug.
The list of authors for NagAuthorException verbose (although unused)
would be more appropriate to simply include all authors, as opposed to
the first appearing.
This change lets JavaPluginLoader use a temporary HashSet to store
methods that could possibly have the EventHandler annotation. Duplicates
are prevented by the nature of a Set.
Registering parent listeners is a breaking change for any listener
extending another listener and expecting parent listeners to not be
called. Changing this is justified by the ease-of-use and proper object
inheritance design. If this is undesired behavior, the method may be
overridden without reapplying the method with the EventHandler notation.
This metadata implementation has the following features:
- All metadata is lazy. Metadata values are not actually computed until another plugin requests them. Memory and CPU are conserved by not computing and storing unnecessary metadata values.
- All metadata is cached. Once a metadata value is computed its value is cached in the metadata store to prevent further unnecessary computation. An invalidation mechanism is provided to flush the cache and force recompilation of metadata values.
- All metadata is stored in basic data types. Convenience methods in the MetadataValue class allow for the conversion of metadata data types when possible. Restricting metadata to basic data types prevents the accidental linking of large object graphs into metadata. Metadata is persistent across the lifetime of the application and adding large object graphs would damage garbage collector performance.
- Metadata access is thread safe. Care has been taken to protect the internal data structures and access them in a thread safe manner.
- Metadata is exposed for all objects that descend from Entity, Block, and World. All Entity and World metadata is stored at the Server level and all Block metadata is stored at the World level.
- Metadata is NOT keyed on references to original objects - instead metadata is keyed off of unique fields within those objects. Doing this allows metadata to exist for blocks that are in chunks not currently in memory. Additionally, Player objects are keyed off of player name so that Player metadata remains consistent between logins.
- Metadata convenience methods have been added to all Entities, Players, Blocks, BlockStates, and World allowing direct access to an individual instance's metadata.
- Players and OfflinePlayers share a single metadata store, allowing player metadata to be manipulated regardless of the player's current online status.
Removed internal collection leaks from PluginDescriptionFile
BREAKING: PluginDescriptionFile.getAuthors() now returns List instead of
ArrayList
Various places with unsafe generics, notably List<Object> getList() in
Configurations are now referenced as <?>. This is nonbreaking, but
sourcecode will need to be revised when compiled.
Removed throwable and message, because the superclass already stores them
Added message of inner exception to the outer exception to make the first line of the stacktrace more verbose
