void addVariableNames(Collection<String> variableNames)

Adds any external variables to the variableNames collection.

Parameters:

variableNames - the collection to add to

setVariableValue

void setVariableValue(String name,
                      String value)

Set the named variable to the specified value. If value is null, then the variable will be removed ( ie. a call to getVariableValue will return null )
