Decodes resources that are encoded into a Cramfull subclass.
The method byte decode(int iEncodedLength) is invoked on the
implementing subclass, which has access to the method
int read() to read the encoded char sequence.
IMPORTANT: Subclasses should be public and either have no
constructor declaration or have a public constructor that takes no arguments.
Example implementations are given in the package be.arci.pub.
Decodes a resource from a sequence of char-s. This is the reverse process of the
corresponding Encoder's void encode(DataInput di, int iResourceLength).
Implementations must invoke the method int read() to retrieve the encoded char-s of
iEncodedLength - the length in char-s of the encoded form of the resource
the bytes of the decoded resource, as they were read in by the ClassCompiler
from the original resource file. If a decoding error occurs, the implementing subclass has the
choice of either returning the value null, or throwing a ResourceDecodingException
giving more detailed info on the decoding error.
ResourceDecodingException - if a decoding error occurs and the implementing
subclass wants to give a more detailed message about the decoding error.
