Class Boot

java.lang.Object

java.lang.ClassLoader

water.Boot

public class Boot
extends java.lang.ClassLoader

Initializer class for H2O. Unpacks all the dependencies and H2O implementation from the jar file, sets the loader to be able to load all the classes properly and then executes the main method of the H2O class. Does nothing if the H2O is not run from a jar archive. (This *is* a feature, at least for the time being so that we can continue using different IDEs).
