                                            LogicalOperator operator)

Returns the exceptions associated with the given operator. Returns the empty list if the given operator is not found in the graph.

Parameters:

instance - the logical graph instance

operator - the operator

Returns:

a list of exceptions

getConnectionStatistics

public static List<LogicalStatistic> getConnectionStatistics(LogicalGraphInstance instance,
