Examples of com.google.gwt.dev.cfg.PropertyPermutations

com.google.gwt.dev.cfg.PropertyPermutations
Generates all possible permutations of properties in a module. Each permutation consists of the list of active property values associated with that permutation. That list of property values is represented as an array of Strings corresponding to the list of properties returned by {@link Properties#getBindingProperties()}.
