AssociationListUtil

public AssociationListUtil()

Method Detail

get

public static java.util.List<java.lang.Object> get(com.sas.metadata.remote.AssociationList acList)

Returns the items in the association list, guarding against a concurrent modification exception for either 10 attempts or for the value of the system property "IQ.RetryUtil.MaxRetries". If that property is set to less than 1, then no retries will be made.

Parameters:

acList - AssociationList to retrieve the members from.

Returns:

filteredSnapshot

public static <T> java.util.List<T> filteredSnapshot(com.sas.metadata.remote.AssociationList acList,
                                                     java.lang.Class<T> type)

Returns a filtered snapshot of the association list that is safe for iteration.

A ConcurrentModificationException is guarded against for either 10 attempts or for the value of the system property "IQ.RetryUtil.MaxRetries". If that property is set to less than 1, then no retries will be made.

All elements in the returned list will be of type type, and none of the elements will be null. In other words, the returned list is a filtered snapshot of the input list.

Parameters:

acList - the original AssociationList

type - the type parameter for the legacy (pre-generic) association list.

Throws:

java.lang.IllegalStateException - when a snapshot can not be obtained

java.lang.ClassCastException - if elements in the association list are not of type type
