Represents the Bukkit core, for version and Server singleton handling

  • Method Details

    • getServer

      @NotNull public static @NotNull Server getServer()
      Gets the current Server singleton
      Returns:
      Server instance being ran

    • getPluginsFolder

      @NotNull public static @NotNull File getPluginsFolder()
      Returns the de facto plugins directory, generally used for storing plugin jars to be loaded, as well as their data folders.

      Plugins should use Plugin.getDataFolder() rather than traversing this directory manually when determining the location in which to store their data and configuration files.

      Returns:
      plugins directory

    • setServer

      public static void setServer(@NotNull @NotNull Server server)
      Attempts to set the Server singleton.

      This cannot be done if the Server is already set.

      Parameters:
      server - Server instance

    • getVersionMessage

      @NotNull public static @NotNull String getVersionMessage()
      Gets message describing the version server is running.
      Returns:
      message describing the version server is running

    • getName

      @NotNull public static @NotNull String getName()
      Gets the name of this server implementation.
      Returns:
      name of this server implementation

    • getVersion

      @NotNull public static @NotNull String getVersion()
      Gets the version string of this server implementation.
      Returns:
      version of this server implementation

    • getBukkitVersion

      version of Bukkit

    • getMinecraftVersion

      @NotNull public static @NotNull String getMinecraftVersion()
      Gets the version of game this server implements
      Returns:
      version of game

    • getOnlinePlayers

      @NotNull public static @NotNull Collection<? extends Player> getOnlinePlayers()
      Gets a view of all currently logged in players. This view is a reused object, making some operations like Collection.size() zero-allocation.

      The collection is a view backed by the internal representation, such that, changes to the internal state of the server will be reflected immediately. However, the reuse of the returned collection (identity) is not strictly guaranteed for future or all implementations. Casting the collection, or relying on interface implementations (like Serializable or List), is deprecated.

      Iteration behavior is undefined outside of self-contained main-thread uses. Normal and immediate iterator use without consequences that affect the collection are fully supported. The effects following (non-exhaustive) teleportation, death, and kicking are undefined. Any use of this collection from asynchronous threads is unsafe.

      For safe consequential iteration or mimicking the old array behavior, using Collection.toArray(Object[]) is recommended. For making snapshots, ImmutableList.copyOf(Collection) is recommended.

      Returns:
      a view of currently online players.

      Selects entities using the given Vanilla selector.
      No guarantees are made about the selector format, other than they match the Vanilla format for the active Minecraft version.
      Usually a selector will start with '@', unless selecting a Player in which case it may simply be the Player's name or UUID.
      Note that in Vanilla, elevated permissions are usually required to use '@' selectors, but this method should not check such permissions from the sender.
      Parameters:
      sender - the sender to execute as, must be provided
      selector - the selection string
      Returns:
      a list of the selected entities. The list will not be null, but no further guarantees are made.

    • createProfile

      @NotNull public static PlayerProfile createProfile(@NotNull @NotNull UUID uuid)
      Creates a PlayerProfile for the specified uuid, with name as null. If a player with the passed uuid exists on the server at the time of creation, the returned player profile will be populated with the properties of said player (including their uuid and name).
      Parameters:
      uuid - UUID to create profile for
      Returns:
      A PlayerProfile object

    • createProfile

      @NotNull public static PlayerProfile createProfile(@NotNull @NotNull String name)
      Creates a PlayerProfile for the specified name, with UUID as null. If a player with the passed name exists on the server at the time of creation, the returned player profile will be populated with the properties of said player (including their uuid and name).

      E.g. if the player 'jeb_' is currently playing on the server, calling createProfile("JEB_") will yield a profile with the name 'jeb_', their uuid and their textures. To bypass this pre-population on a case-insensitive name match, see createProfileExact(UUID, String).

      Parameters:
      name - Name to create profile for
      Returns:
      A PlayerProfile object

    • createProfile

      @NotNull public static PlayerProfile createProfile(@Nullable @Nullable UUID uuid, @Nullable @Nullable String name)
      Creates a PlayerProfile for the specified name/uuid Both UUID and Name can not be null at same time. One must be supplied. If a player with the passed uuid or name exists on the server at the time of creation, the returned player profile will be populated with the properties of said player (including their uuid and name).

      E.g. if the player 'jeb_' is currently playing on the server, calling createProfile(null, "JEB_") will yield a profile with the name 'jeb_', their uuid and their textures. To bypass this pre-population on an case-insensitive name match, see createProfileExact(UUID, String).

      The name comparison will compare the String.toLowerCase() version of both the passed name parameter and a players name to honour the case-insensitive nature of a mojang profile lookup.

      Parameters:
      uuid - UUID to create profile for
      name - Name to create profile for
      Returns:
      A PlayerProfile object

    • createProfileExact

      @NotNull public static PlayerProfile createProfileExact(@Nullable @Nullable UUID uuid, @Nullable @Nullable String name)
      Creates an exact PlayerProfile for the specified name/uuid Both UUID and Name can not be null at same time. One must be supplied. If a player with the passed uuid or name exists on the server at the time of creation, the returned player profile will be populated with the properties of said player.

      Compared to createProfile(UUID, String), this method will never mutate the passed uuid or name. If a player with either the same uuid or a matching name (case-insensitive) is found on the server, their properties, such as textures, will be pre-populated in the profile, however the passed uuid and name stay intact.

      Parameters:
      uuid - UUID to create profile for
      name - Name to create profile for
      Returns:
      A PlayerProfile object

      @NotNull public static RegionScheduler getRegionScheduler()
      Returns the region task scheduler. The region task scheduler can be used to schedule tasks by location to be executed on the region which owns the location.

      Note: It is entirely inappropriate to use the region scheduler to schedule tasks for entities.
