Class Environment

java.lang.Object

ch.sf.htt.Environment

public class Environment
extends java.lang.Object

Abstracts environment variables. On Windows names of environment variables are not case sensitive. If the OS is Windows, names of environment variables are converted to all lower case, e.g. "Path" to "path": All methods that are given names of environment variables can use any case, i.e. are converted to lower case within the method; returned names of environment variables are all lower case. On all other OSes no conversion is done.
