Method Detail

modify

public static java.lang.Object modify(java.lang.Object obj,
                                      java.lang.String modifications)

Returns a modified copy of the object.

Parameters:

modifications - a comma or semi-colon separated list of strings of the form LHS=RHS, where RHS is something that can be passed to toObject(), and LHS is a period-separated chain of getters/setters, where only the last item is a setter.

Example:
RefUtils.modify( new StackedSequenceLearner(new MaxEntLearner(),1),
"params.historySize=1,params.futureSize=0")
is the same as: StackedSequenceLearner a = new StackedSequenceLearner(new MaxEntLearner(),1);
a.getParams().setHistorySize(1);
a.getParams().setFutureSize(0);
