## cpw.mods.fml.common
Class Loader

    java.lang.Object
      cpw.mods.fml.common.Loader

    public class Loader

extends Object

The loader class performs the actual loading of the mod code from disk.

There are several `LoaderState`s to mod loading, triggered in two different stages from the FML handler code's hooks into the minecraft code.

1. LOADING. Scanning the filesystem for mod containers to load (zips, jars, directories), adding them to the `modClassLoader` Scanning, the loaded containers for mod classes to load and registering them appropriately.
2. PREINIT. The mod classes are configured, they are sorted into a load order, and instances of the mods are constructed.
3. INIT. The mod instances are initialized. For BaseMod mods, this involves calling the load method.
4. POSTINIT. The mod instances are post initialized. For BaseMod mods this involves calling the modsLoaded method.
5. UP. The Loader is complete
6. ERRORED. The loader encountered an error during the LOADING phase and dropped to this state instead. It will not complete loading from this state, but it attempts to continue loading before abandoning and giving a fatal error.

Phase 1 code triggers the LOADING and PREINIT states. Phase 2 code triggers the INIT and POSTINIT states.

Method Detail

### instance

    public static Loader instance()

### injectData

    public static void injectData(Object... data)

### getModList

    public List<ModContainer> getModList()

### loadMods

    public void loadMods()

  Called from the hook to start mod loading. We trigger the `identifyMods()` and Constructing, Preinitalization, and Initalization phases here. Finally, the mod list is frozen completely and is consider immutable from then on.

### isModLoaded

    public static boolean isModLoaded(String modname)

  Query if we know of a mod named modname

  Parameters:
    `modname` -
  Returns:
    If the mod is loaded

### getConfigDir

    public File getConfigDir()

### getCrashInformation

    public String getCrashInformation()

### getFMLVersionString

    public String getFMLVersionString()

### getModClassLoader

    public ClassLoader getModClassLoader()

### computeDependencies

    public void computeDependencies(String dependencyString,
                                    Set<ArtifactVersion> requirements,
                                    List<ArtifactVersion> dependencies,
                                    List<ArtifactVersion> dependants)

### getIndexedModList

    public Map<String,ModContainer> getIndexedModList()

### initializeMods

    public void initializeMods()

### getCallableCrashInformation

    public ICrashCallable getCallableCrashInformation()

### getActiveModList

    public List<ModContainer> getActiveModList()

### getModState

    public LoaderState.ModState getModState(ModContainer selectedMod)

### getMCVersionString

    public String getMCVersionString()

### serverStarting

    public void serverStarting(Object server)

### serverStarted

    public void serverStarted()

### serverStopping

    public void serverStopping()

### getModObjectList

    public com.google.common.collect.BiMap<ModContainer,Object> getModObjectList()

### getReversedModObjectList

    public com.google.common.collect.BiMap<Object,ModContainer> getReversedModObjectList()

### activeModContainer

    public ModContainer activeModContainer()

### isInState

    public boolean isInState(LoaderState state)

### getMinecraftModContainer

    public MinecraftDummyContainer getMinecraftModContainer()
