public class BigdataBNodeImpl
extends BigdataResourceImpl
implements BigdataBNode

A blank node. Use BigdataValueFactory to create instances of this class.

Note: When AbstractTripleStore.Options#STATEMENT_IDENTIFIERS is enabled blank nodes in the context position of a statement are recognized as statement identifiers by StatementBuffer. It coordinates with this class in order to detect when a blank node is a statement identifier and to defer the assertion of statements made using a statement identifier until that statement identifier becomes defined by being paired with a statement.
