  • Method Details

    • whichResource

      @Description("returns the URI of the given resource") URI whichResource(String name)
      Looks if the given resource can be found in the classpath.

      To avoid problems like "java.rmi.UnmarshalException: failed to unmarshal class java.lang.Object; nested exception is: java.io.IOException: unknown protocol: zip" no longer a URL but URI is now returned

      Parameters:
      name - of a resource e.g. "log4j.properties"
      Returns:
      URI of the given resource (or null if resource was not found)

    • getResources

      @Description("returns all resources of the classpath") String[] getResources()
      Looks in the normal classpath after all resources and returns it as String array.
      Returns:
      all found resources in the classpath

    • getNoResources

      @Description("how often the given resource is found in the classpath") int getNoResources(String name)
      Get number of resources.
      Parameters:
      name - of the resource
      Returns:
      how often the resource was found

    • isDoublet

      @Description("is the given classname or resource found more than once in the classpath?") boolean isDoublet(String name) throws NoSuchElementException
      Is the given classname or resource a doublet, e.g. can it be found several times in the classpath? If the classname or resource is not in the classpath a java.util.NoSuchElementException will be thrown.
      Parameters:
      name - a classname or resource
      Returns:
      true if more than one classname or resource was found in the classpath
      Throws:
      NoSuchElementException - the no such element exception
      NoSuchElementException - if no classname or resource was found

    • getFirstDoublet

      @Description("returns the first doublet of the given classname or resource") URI getFirstDoublet(String name)
      Returns the first doublet of the given classname or resource.
      Parameters:
      name - a classname or resource
      Returns:
      the first doublet

    • getDoublet

      @Description("returns the n'th doublet of the given classname or resource") URI getDoublet(String name, int n)
      Returns the n'th doublet of the given classname or resource.
      Parameters:
      name - a classname or resource
      n - number of wanted doublet
      Returns:
      the n'th doublet URL

    • getDoublets

      @Description("returns a sorted array of all found doublets") String[] getDoublets()
      Looks for each loaded resource if it has a doublet or not.
      Returns:
      a sorted array with the found doublets

    • getDoubletResourcepath

      @Description("returns the classpath where doublets were found") String[] getDoubletResourcepath()
      Looks for each found doublet resource in which classpath it was found. Resources like META-INF/MANIFEST.MF which you would find each jar file should be not considered as doublet - otherwise you'll find all classpathes in the array.
      Returns:
      the classpath where doublets were found

    • getIncompatibleResources

      @Description("returns the doublet resources with different content") String[] getIncompatibleResources()
      Incompatible resources are doublets with different content.
      Returns:
      doublet resources with different content

    • getIncompatibleResourcepath

      @Description("returns the classpath where incompatible resources were found") String[] getIncompatibleResourcepath()
      Gets the incompatible classpath.
      Returns:
      the classpathes where incompatible classes were found
