Method Detail

degree

public int degree(long nodeId)

Description copied from interface: CompositeRelationshipIterator

Returns the degree of the given node id.

Specified by:

degree in interface CompositeRelationshipIterator

forEachRelationship

public void forEachRelationship(long nodeId,
                                CompositeRelationshipIterator.RelationshipConsumer consumer)

Description copied from interface: CompositeRelationshipIterator

Applies the given consumer on all relationships of the given node id.

Specified by:

forEachRelationship in interface CompositeRelationshipIterator

propertyKeys

public java.lang.String[] propertyKeys()

Description copied from interface: CompositeRelationshipIterator

Returns the property keys that are managed by this iterator. The order is equivalent to the order of the value array in CompositeRelationshipIterator.RelationshipConsumer.consume(long, long, double[]).

Specified by:

propertyKeys in interface CompositeRelationshipIterator

concurrentCopy

public CompositeRelationshipIterator concurrentCopy()

Description copied from interface: CompositeRelationshipIterator

Creates a thread-safe copy of the iterator.

Specified by:

concurrentCopy in interface CompositeRelationshipIterator
