question: private String testComparisonString ( ) { Attribute att = m_Dataset . attribute ( m_AttIndex ) ; if ( att . isNumeric ( ) ) { return ( ( m_Not ? ">= " : "< " ) + Utils . doubleToString ( m_Split , 3 ) ) ; } else { if ( att . numValues ( ) != 2 ) { return ( ( m_Not ? "!= " : "= " ) + att . value ( ( int ) m_Split ) ) ; } else { return ( "= " + ( m_Not ? att . value ( ( int ) m_Split == 0 ? 1 : 0 ) : att . value ( ( int ) m_Split ) ) ) ; } } }
target:  Gives a string representation of the test, starting from the comparison symbol.
