  - findClass
```
protected java.lang.Class<?> findClass(java.lang.String name)
                                throws java.lang.ClassNotFoundException
```
    Find bundle class to load. First check if this load comes from an imported package. Otherwise load class from our bundle.
    
    Overrides:
    
    findClass in class java.lang.ClassLoader
    
    Throws:
    
    java.lang.ClassNotFoundException
    
    See Also:
    
    ClassLoader.findClass(java.lang.String)
  - findLibrary
```
protected java.lang.String findLibrary(java.lang.String name)
```
    Find native library code to load.
    
    Overrides:
    
    findLibrary in class java.lang.ClassLoader
    
    See Also:
    
    ClassLoader.findLibrary(java.lang.String)
  - findResources
```
protected java.util.Enumeration<java.net.URL> findResources(java.lang.String name)
```
    Returns an Enumeration of all the resources with the given name.
    
    Overrides:
    
    findResources in class java.lang.ClassLoader
    
    See Also:
    
    ClassLoader.findResources(java.lang.String)
  - findResource
```
protected java.net.URL findResource(java.lang.String name)
```
    Finds the resource with the given name.
    
    Overrides:
    
    findResource in class java.lang.ClassLoader
    
    See Also:
    
    ClassLoader.findResource(java.lang.String)
  - isBootClassContext
```
public boolean isBootClassContext(java.lang.String name)
```
    Check if the current call is made from a class loaded on the boot class path (or rather, on a class loaded from something else than a bundle class loader)
    
    Parameters:
    
    name - The name of the class to load.
  - loadClass
```
protected java.lang.Class<?> loadClass(java.lang.String name,
                                       boolean resolve)
                                throws java.lang.ClassNotFoundException
```
    Find Class and load it. This function is abstract in PJava 1.2 so we define it here to work as closely as it can to Java 2. Should work okey if we don't use the Java 2 stuff.
    
    Overrides:
    
    loadClass in class java.lang.ClassLoader
    
    Parameters:
    
    name - the name of the class
    
    resolve - if true then resolve the class
    
    Returns:
    
    the resulting Class object
    
    Throws:
    
    java.lang.ClassNotFoundException - if the class could not be found
    
    See Also:
    
    ClassLoader.loadClass(java.lang.String)
  - getResource
```
public java.net.URL getResource(java.lang.String name)
```
    Finds the resource with the given name. This is defined a little different in PJava 1.2 versus Java 2. So we first try to use the super() version and if it fails we try to find it in the local bundle.
    
    Overrides:
    
    getResource in class java.lang.ClassLoader
    
    Parameters:
    
    name - resource name
    
    Returns:
    
    an URL to resource, or null if the resource could not be found or the caller doesn't have adequate privileges to get the resource.
    
    See Also:
    
    ClassLoader.getResource(java.lang.String)
  - getResourcesOSGi
```
public java.util.Enumeration<java.net.URL> getResourcesOSGi(java.lang.String name)
                                                     throws java.io.IOException
```
    Finds all the resources with the given name. A resource is some data (images, audio, text, etc) that can be accessed by class code in a way that is independent of the location of the code.
    The name of a resource is a /-separated path name that identifies the resource.
    
    Parameters:
    
    name - resource name
    
    Returns:
    
    An enumeration of URL objects for the resource. If no resources could be found, the enumeration will be empty. Resources that the class loader doesn't have access to will not be in the enumeration.
    
    Throws:
    
    java.io.IOException
    
    See Also:
    
    ClassLoader.getResources(java.lang.String), Bundle.getResources(String name)
  - getResourceAsStream
```
public java.io.InputStream getResourceAsStream(java.lang.String name)
```
    Finds the resource with the given name and returns the InputStream. The method is overridden to make sure it does the right thing.
    
    Overrides:
    
    getResourceAsStream in class java.lang.ClassLoader
    
    Parameters:
    
    name - resource name
    
    Returns:
    
    an InputStream to resource, or null if the resource could not be found or the caller doesn't have adequate privileges to get the resource.
    
    See Also:
    
    ClassLoader.getResourceAsStream(java.lang.String)
  - toString
```
public java.lang.String toString()
```
    Return a string representing this object
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    A message string.
  - getBundle
```
public Bundle getBundle()
```
    Description copied from interface: BundleReference
    
    Returns the Bundle object associated with this BundleReference.
    
    Specified by:
    
    getBundle in interface BundleReference
    
    Returns:
    
    The Bundle object associated with this BundleReference.
