addAll

public static Set<BindingSet> addAll(Iteration<? extends BindingSet,? extends QueryEvaluationException> arg2,
                                     Set<BindingSet> includeSet,
                                     AtomicLong used,

                              throws QueryEvaluationException

Deprecated, for removal: This API element is subject to removal in a future version.

Parameters:

arg2 - the iteration with elements to add to the includeSet

includeSet - the set that should have all unique elements of arg2

used - the collection size counter of all collections used in answering a query

maxSize - the point at which we throw a new query exception

Returns:

the includeSet

Throws:

QueryEvaluationException - trigerred when maxSize is smaller than the used value

add

public static <V> boolean add(V object,
                              Collection<V> excludeSet,
                              AtomicLong used,
                              long maxSize)
                       throws QueryEvaluationException

Deprecated, for removal: This API element is subject to removal in a future version.

Parameters:

object - object to put in set if not there already.

excludeSet - set that we need to store object in.

used - AtomicLong tracking how many elements we have in storage.

maxSize -

Throws:

QueryEvaluationException - when the object is added to the set and the total elements in all limited size collections exceed the allowed maxSize.
