Detailed Description

template<class PP, class MP, template< typename > class ALLOC, template< typename, typename > class ST>
class vat< ISET_PROP, V_Fkk_MINE_PROP, ALLOC, ST >

Itemset VAT class by partial specialization of the generic VAT class.

In this partial specialization, PP is fixed to no_edges (itemset property), MP is fixed to Fk X Fk and vert_mine (vertical mining with Fk X Fk), ST is the storage type, what needs a base type information, here templatized with P

	)			[inline, static]

Vat Intersection for Itemset patterns.

Parameters:

[in]	vat_i	A pointer to the VAT corresponding to the first pattern.
[in]	vat_j	A pointer to the VAT corresponding to the second pattern.
[out]	cand_sup	An array of pointers to pattern_support class instances that is modified in this routine to hold actual support value.
[in]	is_l2	A boolean to designate whether current VAT intersection is a Level 2 vat_join.

Returns:

A static array of VAT* to hold the pointer to the new VATs generated through the intersection.

Precondition:

cand_sups array holds pointer to pattern_support instances with NO actual support value associated to it.

Postcondition:

cand_sups array holding pattern_support instances HAS acutal support value associated to it.
