question: @ Override public String toString ( boolean freq ) { StringBuffer result = new StringBuffer ( ) ; result . append ( m_attribute . name ( ) + " " ) ; switch ( m_comparison ) { case EQUAL : result . append ( "=" ) ; break ; case LESS_THAN_OR_EQUAL_TO : result . append ( "<=" ) ; break ; case GREATER_THAN : result . append ( ">" ) ; break ; default : break ; } result . append ( " " + Utils . doubleToString ( m_splitPoint , 4 ) ) ; if ( freq ) { result . append ( ":" + m_frequency ) ; } return result . toString ( ) ; }
target:  A string representation of this item, (i.e. <attribute name> <comparison operator> <item value>). This default implementation just prints the attribute name and (optionally) frequency information.
