equals

public final boolean equals(java.lang.Object o)
                     throws ReadDeniedException,
                            AuthenticationRequiredException

An RDFNode is equal to another enhanced node n iff the underlying nodes are equal. We generalise to allow the other object to be any class implementing asNode, because we allow other implementations of Resource, at least in principle. This is deemed to be a complete and correct interpretation of RDFNode equality, which is why this method has been marked final.

Specified by:

equals in interface SecuredItem

Overrides:

equals in class SecuredItemImpl

Parameters:

o - An object to test for equality with this node

Returns:

True if o is equal to this node.

Throws:

ReadDeniedException

AuthenticationRequiredException

hashCode

public final int hashCode()

The hash code of an RDFnode is defined to be the same as the underlying node.

Overrides:

hashCode in class SecuredItemImpl

Returns:

The hashcode as an int
