Detailed Description

Builder for constructing AutocompleteEngine instances.

Constructor & Destructor Documentation

Builder()

Builder

(

)

Constructs a new AutocompleteEngine.Builder.

        {
            this.analyzer = new Analyzer()
            {
                @Override
                public Collection<String> apply(Collection<String> input)
                {
                    return new ArrayList<>(input);
                }
            };
        }
