decode

protected String decode(String filename)

Deprecated.

Inverse of encode exept it do not use path. So decode(encode(s) - m_path) = s. In other words it returns a String that can be used as key to retive the record contained in the 'filename' file.

encode

public String encode(String s)

Deprecated.

Returns a String that uniquely identifies the object. Note: since this method uses the Object.toString() method, it's up to the caller to make sure that this method doesn't change between different JVM executions (like it may normally happen). For this reason, it's highly recommended (even if not mandated) that Strings be used as keys.
