    Description copied from interface: IClassLoader
    
    Find and return the IClass defined by this class loader that corresponds to the given class name.
    
    Specified by:
    
    lookupClass in interface IClassLoader
    
    Parameters:
    
    className - name of the class
    
    Returns:
    
    the IClass defined by this class loader that corresponds to the given class name, or null if not found.
  - iterateAllClasses
```
public Iterator<IClass> iterateAllClasses()
```
    Specified by:
    
    iterateAllClasses in interface IClassLoader
    
    Returns:
    
    an Iterator of all classes loaded by this loader
  - getNumberOfClasses
```
public int getNumberOfClasses()
```
    Specified by:
    
    getNumberOfClasses in interface IClassLoader
    
    Returns:
    
    the number of classes in scope to be loaded by this loader
  - getName
```
public Atom getName()
```
    Specified by:
    
    getName in interface IClassLoader
    
    Returns:
    
    the unique name that identifies this class loader.
  - getNumberOfMethods
```
public int getNumberOfMethods()
```
    Specified by:
    
    getNumberOfMethods in interface IClassLoader
  - getSourceFileName
```
public String getSourceFileName(IMethod method,
                                int bcOffset)
```
    Specified by:
    
    getSourceFileName in interface IClassLoader
    
    Parameters:
    
    method - The method for which information is desired
    
    bcOffset - an offset into the bytecode of the given method.
    
    Returns:
    
    name of the source file corresponding to the given offset in the given method. Note that this api allows a single method to arise from multiple source files, which is deliberate as it can happen in some languages.
  - getSourceFileName
```
public String getSourceFileName(IClass klass)
```
    Specified by:
    
    getSourceFileName in interface IClassLoader
    
    Parameters:
    
    klass - the class for which information is desired.
    
    Returns:
    
    name of source file corresponding to the class, or null if not available
  - getSource
```
public Reader getSource(IClass klass)
```
    Specified by:
    
    getSource in interface IClassLoader
    
    Returns:
    
    input stream representing the source file for a class, or null if not available
  - getSource
```
public Reader getSource(IMethod method,
                        int bcOffset)
```
    Specified by:
    
    getSource in interface IClassLoader
    
    Parameters:
    
    method - The method for which information is desired
    
    bcOffset - an offset into the bytecode of the given method.
    
    Returns:
    
    input stream representing the source file for a given bytecode index of a given method, or null if not available
  - getParent
```
public IClassLoader getParent()
```
    Specified by:
    
    getParent in interface IClassLoader
    
    Returns:
    
    the parent IClassLoader, if any, or null
  - removeAll
```
public void removeAll(Collection<IClass> toRemove)
```
    Description copied from interface: IClassLoader
    
    blow away references to any classes in the set
    
    Specified by:
    
    removeAll in interface IClassLoader
    
    Parameters:
    
    toRemove - Collection
