    • protocol

      public String protocol
      Since the Data instance is 'hidden' in the ParsedURL instance we make all our methods public. This makes it easy for the various Protocol Handlers to update an instance as parsing proceeds.

    • checkGZIP

      public static InputStream checkGZIP(InputStream is) throws IOException
      This is a utility function others can call that checks if is is a GZIP stream if so it returns a GZIPInputStream that will decode the contents, otherwise it returns (or a buffered version of is) untouched.
      Parameters:
      is - Stream that may potentially be a GZIP stream.
      Throws:
      IOException

    • buildURL

      Returns:
      the connect timeout.

    • setConnectTimeout

      public static void setConnectTimeout(int connectTimeout)
      Sets the connect timeout.

      Default is 10 seconds.

      Parameters:
      connectTimeout - the connect timeout.

    • getContentType

      public String getContentType(String userAgent)
      Returns the content type if available. This is only available for some protocols.

    • getContentTypeMediaType

      public String getContentTypeMediaType(String userAgent)
      Returns the content type's type/subtype, if available. This is only available for some protocols.

    • getContentTypeCharset

      public String getContentTypeCharset(String userAgent)
      Returns the content type's charset parameter, if available. This is only available for some protocols.

      Returns whether the Content-Type header has the given parameter.

    • extractContentTypeParts

      protected void extractContentTypeParts(String userAgent)
      Extracts the type/subtype and charset parameter from the Content-Type header.

    • getContentEncoding

      public String getContentEncoding(String userAgent)
      Returns the content encoding if available. This is only available for some protocols.

    • complete

      public boolean complete()
      Returns true if the URL looks well formed and complete. This does not garuntee that the stream can be opened but is a good indication that things aren't totally messed up.

    • openStream

      public InputStream openStream(String userAgent, Iterator<String> mimeTypes) throws IOException
      Open the stream and check for common compression types. If the stream is found to be compressed with a standard compression type it is automatically decompressed.
      Parameters:
      userAgent - The user agent opening the stream (may be null).
      mimeTypes - The expected mime types of the content in the returned InputStream (mapped to Http accept header among other possability). The elements of the iterator must be strings (may be null)
      Throws:
      IOException

    • openStreamRaw

      public InputStream openStreamRaw(String userAgent, Iterator<String> mimeTypes) throws IOException
      Open the stream and returns it. No checks are made to see if the stream is compressed or encoded in any way.
      Parameters:
      userAgent - The user agent opening the stream (may be null).
      mimeTypes - The expected mime types of the content in the returned InputStream (mapped to Http accept header among other possability). The elements of the iterator must be strings (may be null)
      Throws:
      IOException

    • openStreamInternal

      protected InputStream openStreamInternal(String userAgent, Iterator<String> mimeTypes, Iterator<String> encodingTypes) throws IOException
      Throws:
      IOException

    • getPortStr

      public String getPortStr()
      Returns the URL up to and include the port number on the host. Does not include the path or fragment pieces.

    • sameFile

      protected boolean sameFile(ParsedURLData other)

    • toString

      public String toString()
      Return a string representation of the data.
      Overrides:
      toString in class Object

    • getPostConnectionURL
