      java.util.Enumeration<java.net.URL> getResources​(java.lang.String name)
      Allows the standard ClassLoader.getResources() mechanisms to be replaced with a different implementation.
      boolean isLocallyDefined​(java.lang.String classname)

    • Method Detail

      • getResources

        java.util.Enumeration<java.net.URL> getResources​(java.lang.String name)
                                          throws java.io.IOException
        Allows the standard ClassLoader.getResources() mechanisms to be replaced with a different implementation. In an OSGi environment, this will allow for filtering to take place on the results of ClassLoader.getResources(). In a non-OSGi environment, ClassLoader.getResources should be returned.
        Parameters:
        name - the name of the resource to search for
        Returns:
        an enumeration containing all of the matching resources found
        Throws:
        java.io.IOException

      • getBundleIdFromURL

        java.lang.String getBundleIdFromURL​(java.net.URL url)
        Deprecated.
        use getFile() or getClassLoaderName()
        In an OSGi environment, determin which bundle a URL originated from. In a non-OSGi environment, implementors should return null.
        Parameters:
        url -
        Returns:

      • getClassLoaderName

        java.lang.String getClassLoaderName()
        In an environment with multiple class loaders allows each to be identified using something safer and possibly shorter than toString
        Returns:
        name of the associated class loader

      • getClassLoader

        java.lang.ClassLoader getClassLoader()

      • getFile

        java.lang.String getFile​(java.net.URL url)
        Format a URL
        Returns:
        filename

      • getId

        java.lang.String getId()
        In an environment with multiple class loaders allows messages to identified according to the weaving context
        Returns:
        short name

      • isLocallyDefined

        boolean isLocallyDefined​(java.lang.String classname)
        Return true if the classloader associated with this weaving context is the one that will define the class with the specified name. In a delegating classloader hierarchy this might check the parent won't define it and the child will - in OSGi it will do something else.
        Parameters:
        classname - name of the class, eg. "java.lang.String"
        Returns:
        true if the associated classloader will define the class

      • getDefinitions

        java.util.List<Definition> getDefinitions​(java.lang.ClassLoader loader,
                                          WeavingAdaptor adaptor)
        Allow custom parsing of aop.xml or alternative mechanism for providing Definitions
        Parameters:
        loader -
        adaptor -
        Returns:
        List containing 0 or more Definition instances
