      • load

        public static Document load​(java.io.File in,
                            java.lang.String charsetName,
                            java.lang.String baseUri)
                     throws java.io.IOException
        Loads and parses a file to a Document. Files that are compressed with gzip (and end in .gz or .z) are supported in addition to uncompressed files.
        Parameters:
        in - file to load
        charsetName - (optional) character set of input; specify null to attempt to autodetect. A BOM in the file will always override this setting.
        baseUri - base URI of document, to resolve relative links against
        Returns:
        Document
        Throws:
        java.io.IOException - on IO error

      • load

        public static Document load​(java.io.InputStream in,
                            java.lang.String charsetName,
                            java.lang.String baseUri)
                     throws java.io.IOException
        Parses a Document from an input steam.
        Parameters:
        in - input stream to parse. You will need to close it.
        charsetName - character set of input
        baseUri - base URI of document, to resolve relative links against
        Returns:
        Document
        Throws:
        java.io.IOException - on IO error

      • load

        public static Document load​(java.io.InputStream in,

                            Parser parser)
                     throws java.io.IOException
        Parses a Document from an input steam, using the provided Parser.
        Parameters:
        in - input stream to parse. You will need to close it.
        charsetName - character set of input
        baseUri - base URI of document, to resolve relative links against
        parser - alternate parser to use.
        Returns:
        Document
        Throws:
        java.io.IOException - on IO error

                  throws java.io.IOException
        Writes the input stream to the output stream. Doesn't close them.
        Parameters:

        public static java.nio.ByteBuffer readToByteBuffer​(java.io.InputStream inStream,
                                                   int maxSize)
                                            throws java.io.IOException
        Read the input stream into a byte buffer. To deal with slow input streams, you may interrupt the thread this method is executing on. The data read until being interrupted will be available.
        Parameters:
        inStream - the input stream to read from
        maxSize - the maximum size in bytes to read from the stream. Set to 0 to be unlimited.
        Returns:
        the filled byte buffer
        Throws:
        java.io.IOException - if an exception occurs whilst reading from the input stream.

      • emptyByteBuffer

        static java.nio.ByteBuffer emptyByteBuffer()

      • getCharsetFromContentType

        static java.lang.String getCharsetFromContentType​(java.lang.String contentType)
        Parse out a charset from a content type header. If the charset is not supported, returns null (so the default will kick in.)
        Parameters:
        contentType - e.g. "text/html; charset=EUC-JP"
        Returns:
        "EUC-JP", or null if not found. Charset is trimmed and uppercased.
