Detailed Description

template<class CODER>
class StatCoder< CODER >

This class assigns 0,1,.

.. new codes to the frequent items. Actually, this class can be regarded as a wrapper around a transaction reader, that changes the items of the read in transaction with new codes. Obviuosly, when an itemset is written out, the items must be decoded. Writting out a coded itemset, however, is not the duty of the StatCoder class but rather the duty of a decoder. After the StatCoder generated the new codes it calls the setCodeInverse function of the decoder.

Parameters:

	T_R	the transaction reader
	D	the decoder
