Constructor Detail

TouchDexLoader

public TouchDexLoader(String path,
                      ClassLoader parent)

Create a ClassLoader that finds files in the specified path.

Method Detail

findClass

protected Class<?> findClass(String name)
                      throws ClassNotFoundException

Find the class with the specified name. None of our ancestors were able to find it, so it's up to us now. "name" is a "binary name", e.g. "java.lang.String" or "java.net.URLClassLoader$3$1". This method will either return a valid Class object or throw an exception. Does not return null.

Overrides:

findClass in class ClassLoader

Parameters:

name - The name of the class to search for.

Returns:

The class or null.

Throws:

ClassNotFoundException - if the class cannot be found.

findResource

protected URL findResource(String name)

Description copied from class: ClassLoader

Returns an URL which can be used to access the resource described by resName, using the class loader's resource lookup algorithm. The default behavior is just to return null. This should be implemented by a ClassLoader.

Overrides:

findResource in class ClassLoader

Parameters:

name - The name of the resource to find.

Returns:

The location of the resource.

findLibrary

protected String findLibrary(String libname)

Find a native library. Return the full pathname of the first appropriate-looking file we find.

Overrides:

findLibrary in class ClassLoader

Parameters:

libname - The name of the library to find.

Returns:

The library file name or null.
