Class BulkSet<S>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<S>

org.apache.tinkerpop.gremlin.process.traversal.step.util.BulkSet<S>

All Implemented Interfaces:

Serializable, Iterable<S>, Collection<S>, Set<S>

public final class BulkSet<S>
extends AbstractSet<S>
implements Set<S>, Serializable

BulkSet is a weighted set (i.e. a multi-set). Objects are added along with a bulk counter the denotes how many times the object was added to the set. Given that count-based compression (vs. enumeration) can yield large sets, methods exist that are long-based (2^64).

Method Details

getAllContainedElementsClass

public Class<?> getAllContainedElementsClass()

Returns:

the class of all contained elements/objects if it is guaranteed that all are of the same type/class (but not necessarily, i.e., they can have the same type/class, but we may return null here if it was not analysed/identified). If no common class was identified, then null is returned.

allContainedElementsSameClass

public boolean allContainedElementsSameClass()

Returns:

true if it is guaranteed that all contained elements/objects are of the same type/class and not null (but not necessarily, i.e., they can have the same type/class, but we may return false here if it was not analysed/identified)
