Example 6 with WriteOutContentHandler

use of org.apache.tika.sax.WriteOutContentHandler in project tika by apache.

the class SpringExample method main.

public static void main(String[] args) throws Exception {

Example 7 with WriteOutContentHandler

use of org.apache.tika.sax.WriteOutContentHandler in project tika by apache.

the class Tika method parseToString.

/**

     * The given input stream is closed by this method.
     * <p>
     * To avoid unpredictable excess memory use, the returned string contains
     * only up to {@link #getMaxStringLength()} first characters extracted
     * from the input document. Use the {@link #setMaxStringLength(int)}
     * method to adjust this limitation.
     * <p>
     * <strong>NOTE:</strong> Unlike most other Tika methods that take an
     * {@link InputStream}, this method will close the given stream for
     * you as a convenience. With other methods you are still responsible
     * for closing the stream or a wrapper instance returned by Tika.
     *
     * @param stream the document to be parsed
     * @param metadata document metadata
     * @return extracted text content
     * @throws IOException if the document can not be read
     * @throws TikaException if the document can not be parsed
