com.izforge.izpack.util.VariableSubstitutor
Substitutes variables occurring in an input stream or a string. This implementation supports a generic variable value mapping and escapes the possible special characters occurring in the substituted values. The file types specifically supported are plain text files (no escaping), Java properties files, and XML files. A valid variable name matches the regular expression [a-zA-Z][a-zA-Z0-9_]* and names are case sensitive. Variables are referenced either by $NAME or ${NAME} (the latter syntax being useful in situations like ${NAME}NOTPARTOFNAME). If a referenced variable is undefined then it is not substituted but the corresponding part of the stream is copied as is. @author Johannes Lehtinen
