Output adapters

Output adapters are used to output generated HTML text to various output objects. The following output adapters are currently supported:

  • FileOutputAdapter is an output adapter that is used to output text to a file. The path to a file is specified in the constructor of the adapter.
  • StreamOutputAdapter is an output adapter that is used to output text to a stream. The stream is specified in the constructor of the adapter.
  • StringOutputAdapter is an output adapter that is used to output text to a string. The resulting string can be accessed through the getResult method of the adapter class.

The example below demonstates how to use adapters of different types.

String indexFolder = "c:\\MyIndex\\";
String documentsFolder = "c:\\MyDocuments\\";
// Creating an index in the specified folder
Index index = new Index(indexFolder);
// Indexing documents from the specified folder
// Getting list of indexed documents
DocumentInfo[] documents = index.getIndexedDocuments();
// Getting a document text
if (documents.length > 0) {
    DocumentInfo document = documents[0];
    // Output to a file
    FileOutputAdapter fileOutputAdapter = new FileOutputAdapter("C:\\Text.html");
    index.getDocumentText(document, fileOutputAdapter);
    // Output to a stream
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    StreamOutputAdapter streamOutputAdapter = new StreamOutputAdapter(stream);
    index.getDocumentText(document, streamOutputAdapter);
    // Output to a string
    StringOutputAdapter stringOutputAdapter = new StringOutputAdapter();
    index.getDocumentText(document, stringOutputAdapter);
    String result = stringOutputAdapter.getResult();
