KDDMLObjectType getType ()

Detailed Description

A condition as used in a KDD Query. This object is used to represent language conditions. The condition can be used to evaluate boolean operators (such as “<”) on table attributes and/or constants. Here, table attributes stand for both relational (or preprocessing) table columns and model properties (e.g. the support of an association rule). Table attributes can be referred using the special symbol "@" in the value attribute. The Condition is composed by an AND, OR, NOT combination between primitive cases. Each base condition can be expressed using the attribute op type, representing the name of the used boolean operator. The terms of that operator can be given using the term XML attributes. Operators can be unary, binary or ternary.
