Constructor Summary

SearchpathFinder(String path)
Create a finder using the supplied classpath.

Method Summary

protected void	finalize()
byte[]	getClassfile(String className) Retrieve the class file that is used to define the named class.
long	getClassfileHash(String className) Return the hash of the bytes that would be returned by getClassfile() with the same arguments.
String	getPath() Returns the constructor's argument.
File[]	getPathArray() Returns the path split out into individual components.
static String[]	splitPath(String path) Split a search path into components.

getClassfile

public byte[] getClassfile(String className)
                    throws ClassNotFoundException

Description copied from interface: ClassfileFinder

Retrieve the class file that is used to define the named class. This is a capability specific to the JC virtual machine.

Specified by:

className - Class name (with slashes, not dots)

Throws:

ClassNotFoundException - if class is not found

getClassfileHash

public long getClassfileHash(String className)
                      throws ClassNotFoundException

Description copied from interface: ClassfileFinder

Return the hash of the bytes that would be returned by getClassfile() with the same arguments. The hash of a class file is defined as the last 16 bytes of the MD5 of the class file.

Specified by:

getClassfileHash in interface ClassfileFinder

Parameters:

className - Class name (with slashes, not dots)

Throws:

ClassNotFoundException - if class is not found

finalize

protected void finalize()

splitPath

public static String[] splitPath(String path)
