com.ctc.wstx.util.URLUtil
public final class URLUtil extends Object

  • Field Details

    • URI_WINDOWS_FILE_PATTERN

      private static final Pattern URI_WINDOWS_FILE_PATTERN
      While URIs that contain pipe are wrong, we'll work around that for [WSTX-275].

  • Method Details

    • urlFromSystemId

      public static URL urlFromSystemId(String sysId) throws IOException
      Method that tries to figure out how to create valid URL from a system id, without additional contextual information. If we could use URIs this might be easier to do, but they are part of JDK 1.4, and preferably code should only require 1.2 (or maybe 1.3)
      Throws:
      IOException

    • uriFromSystemId

      public static URI uriFromSystemId(String sysId) throws IOException
      Throws:
      IOException
      Since:
      4.1

    • urlFromSystemId

      public static URL urlFromSystemId(String sysId, URL ctxt) throws IOException
      Throws:
      IOException

    • urlFromCurrentDir

      public static URL urlFromCurrentDir() throws IOException
      Method that tries to create and return URL that denotes current working directory. Usually used to create a context, when one is not explicitly passed.
      Throws:
      IOException

    • inputStreamFromURL

      public static InputStream inputStreamFromURL(URL url) throws IOException
      Method that tries to get a stream (ideally, optimal one) to read from the specified URL. Currently it just means creating a simple file input stream if the URL points to a (local) file, and otherwise relying on URL classes input stream creation method.
      Throws:
      IOException

    • outputStreamFromURL

      public static OutputStream outputStreamFromURL(URL url) throws IOException
      Method that tries to get a stream (ideally, optimal one) to write to the resource specified by given URL. Currently it just means creating a simple file output stream if the URL points to a (local) file, and otherwise relying on URL classes input stream creation method.
      Throws:
      IOException

    • toURL

      public static URL toURL(File f) throws IOException
      Helper method that will convert given file into equivalent URL. Encapsulated as a separate method to allow for working around problems with deprecation of File.toURL() method.
      Throws:
      IOException

    • cleanSystemId

      private static String cleanSystemId(String sysId)

    • throwIOException

      private static void throwIOException(Exception mex, String sysId) throws IOException
      Helper method that tries to fully convert strange URL-specific exception to more general IO exception. Also, to try to use JDK 1.4 feature without creating requirement, uses reflection to try to set the root cause, if we are running on JDK1.4
      Throws:
      IOException
