Method NewAnonymous

NewAnonymous(Func<String, TextReader, TokenStreamComponents>)

Creates a new instance with the ability to specify the body of the CreateComponents(String, TextReader) method through the createComponents parameter. Simple example: 

    var analyzer = Analyzer.NewAnonymous(createComponents: (fieldName, reader) => 
    {
        Tokenizer source = new FooTokenizer(reader);
        TokenStream filter = new FooFilter(source);
        filter = new BarFilter(filter);
        return new TokenStreamComponents(source, filter);
    });

Declaration
public static Analyzer NewAnonymous(Func<string, TextReader, TokenStreamComponents> createComponents)
Parameters
Type Name Description
Func<System.String, TextReader, TokenStreamComponents> createComponents

A delegate method that represents (is called by) the CreateComponents(String, TextReader) method. It accepts a fieldName and a reader and returns the TokenStreamComponents for this analyzer.
Returns
Type Description
Analyzer

A new Lucene.Net.Analysis.Analyzer.AnonymousAnalyzer instance.

NewAnonymous(Func<String, TextReader, TokenStreamComponents>, ReuseStrategy)

Creates a new instance with the ability to specify the body of the CreateComponents(String, TextReader) method through the createComponents parameter and allows the use of a ReuseStrategy. Simple example: 

    var analyzer = Analyzer.NewAnonymous(createComponents: (fieldName, reader) => 
    {
        Tokenizer source = new FooTokenizer(reader);
        TokenStream filter = new FooFilter(source);
        filter = new BarFilter(filter);
        return new TokenStreamComponents(source, filter);
    }, reuseStrategy);

NewAnonymous(Func<String, TextReader, TokenStreamComponents>, Func<String, TextReader, TextReader>)

Creates a new instance with the ability to specify the body of the CreateComponents(String, TextReader) method through the createComponents parameter and the body of the InitReader(String, TextReader) method through the initReader parameter. Simple example: 

    var analyzer = Analyzer.NewAnonymous(createComponents: (fieldName, reader) => 
    {
        Tokenizer source = new FooTokenizer(reader);
        TokenStream filter = new FooFilter(source);
        filter = new BarFilter(filter);
        return new TokenStreamComponents(source, filter);
    }, initReader: (fieldName, reader) => 
    {
        return new HTMLStripCharFilter(reader);
    });
