BNode (Eclipse RDF4J 4.2.4)

All Superinterfaces:

Resource, Serializable, Value

All Known Implementing Classes:

AbstractBNode, LmdbBNode, MemBNode, NativeBNode, SimpleBNode
```
public interface BNode
extends Resource
```
An RDF-1.1 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 Detail
  - isBNode
```
default boolean isBNode()
```
    Description copied from interface: Value
    
    Check if the object is an instance of the given type. Typically 2x than using instanceof.
    For implementers: This default implementation is overridden in the repsective sub-interface.
    
    Specified by:
    
    isBNode in interface Value
    
    Returns:
    
    true if instance of BNode
  - getID
```
String getID()
```
    Retrieves this blank node's identifier.
    
    Returns:
    
    A blank node identifier.
  - equals
```
boolean equals(Object o)
```
    Compares this blank node to another object.
    
    Overrides:
    
    equals in class 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
```
int hashCode()
```
    Computes the hash code of this blank node.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code for this blank node computed as getID().hashCode()
