Interface BNode

All Superinterfaces:

Comparable, Resource, Serializable, Value

All Known Implementing Classes:

BNodeImpl

public interface BNode

extends Resource

A blank node (aka bnode, aka anonymous node). A blank node has an identifier to be able to compare it to other blank nodes internally. Please note that, conceptually, blank node equality can only be determined by examining the statements that refer to them.

Method Summary

boolean	equals(Object o) Compares a blank node object to another object.
String	getID() retrieves this bNode's identifier.
int	hashCode() The hash code of a blank node is defined as the hash code of its identifier: id.hashCode().

Method Detail

getID

public String getID()

retrieves this bNode's identifier.

Returns:

a bnode identifier

equals

public boolean equals(Object o)

Compares a blank node object to another object.

Parameters:

o - The object to compare this blank node to.

Returns:

true if the other object is an instance of BNode and their IDs are equal, false otherwise.

hashCode

public int hashCode()

The hash code of a blank node is defined as the hash code of its identifier: id.hashCode().

Returns:

A hash code for the blank node.
