Loader (CoreMIDI4J 1.6 API)

java.lang.Object
- uk.co.xfactorylibrarians.coremidi4j.Loader

```
public class Loader
extends Object
```
Loads the native library when we are running on a Mac. If necessary, extracts a copy of the library from our jar file to a temporary directory, to save the user the trouble of having to install it on their system. Arranges for that directory to be deleted when we exit. Inspired by the techniques used by usb4java, and the loader written by Klaus Raimer, k@ailis.de

```
public static void load()
                 throws CoreMidiException
```
    Tries to load our native library. Can be safely called multiple times; duplicate attempts are ignored. This method is automatically called whenever any CoreMidi4J class that relies on JNI is loaded. If you need to do it earlier (to catch exceptions for example, or check whether the native library can be used), simply call this method manually.
    
    Throws:
    
    CoreMidiException - if something unexpected happens trying to load the native library on a Mac OS X system.
  - isAvailable
```
public static boolean isAvailable()
                           throws CoreMidiException
```
    Checks whether CoreMidi4J is available on the current system, in other words whether it is a Mac OS X system and the native library was loaded successfully. Will attempt to perform that load if it has not yet occurred.
    
    Returns:
    
    true if this is a Mac OS X system and the native library has been loaded successfully.
    
    Throws:
    
    CoreMidiException - if something unexpected happens trying to load the native library on a Mac OS X system.
