question: private static boolean clearance_equals ( freert . rules . ClearanceMatrix p_cl_matrix , int p_layer_1 , int p_layer_2 ) { if ( p_layer_1 == p_layer_2 ) { return true ; } for ( int i = 1 ; i < p_cl_matrix . get_class_count ( ) ; ++ i ) { for ( int j = i ; j < p_cl_matrix . get_class_count ( ) ; ++ j ) { if ( p_cl_matrix . value_at ( i , j , p_layer_1 ) != p_cl_matrix . value_at ( i , j , p_layer_2 ) ) { return false ; } } } return true ; }
target:  Returns true, if all clearance values on the 2 input layers are equal.
