public class DataFilePaths
extends java.lang.Object
Simple utility class: reads the environment variable in
ENV_VARIABLE and provides a method that converts strings which
start with that environment variable to file paths. For example,
you can send it
"$NLP_DATA_HOME/data/pos-tagger/wsj3t0-18-left3words"
and it will convert that to
"/u/nlp/data/pos-tagger/wsj3t0-18-left3words"
unless you have set $NLP_DATA_HOME to something else.
The only environment variable expanded is that defined by
ENV_VARIABLE, and the only place in the string it is expanded is at
the start of the string.
