Method Details

findClass

public JavaClass findClass(String className)

Description copied from interface: JavaClassLoader

Find a named class within this class loader. The class may have been defined in this class loader, or this class loader may have delegated the load to another class loader and cached the result.

Specified by:

findClass in interface JavaClassLoader

Parameters:

className - of the class to find. Packages should be separated by '/' instead of '.'

Returns:

the JavaClass instance, or null if it is not found

getCachedClasses

public Iterator getCachedClasses()

TODO: javacore appears to only list defined classes per class loader. If this changes in the future, this implementation must be changed.

Specified by:

getCachedClasses in interface JavaClassLoader

Returns:

an iterator over the collection of classes which are defined in this JavaClassLoader or which were found by delegation to other JavaClassLoaders

• JavaClass
• CorruptData

getDefinedClasses

public Iterator getDefinedClasses()

Description copied from interface: JavaClassLoader

Get the set of classes which are defined in this JavaClassLoader.

Specified by:

getDefinedClasses in interface JavaClassLoader

Returns:

an iterator over the collection of classes which are defined in this JavaClassLoader

See Also:

getObject

public JavaObject getObject()
                     throws CorruptDataException

Description copied from interface: JavaClassLoader

Get the java.lang.ClassLoader instance associated with this class loader.

Specified by:

getObject in interface JavaClassLoader

Returns:

a JavaObject representing the java.lang.ClassLoader instance associated with this class loader, or null if there is no Java class loader associated with this low-level class loader.

Throws:

CorruptDataException
