ofClassPath

public static ClassFileLocator ofClassPath()
                                    throws IOException

Resolves a class file locator for the class path that reads class files directly from the file system. The resulting class file locator does not imply classes on the boot path.

Returns:

A class file locator for the class path.

Throws:

IOException - If an I/O exception occurs.

ofClassPath

public static ClassFileLocator ofClassPath(String classPath)
                                    throws IOException

Resolves a class file locator for the runtime jar. If such a file does not exist or cannot be located, a runtime exception is thrown.

Returns:

A class file locator for the runtime jar, if available.

Throws:

IOException - If an I/O exception occurs.

locate

public ClassFileLocator.Resolution locate(String name)
                                   throws IOException
