Method Detail

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: Quad

Check it this Quad is equal to another Quad.

Two Quads are equal if and only if their Quad.getGraphName(), Quad.getSubject(), Quad.getPredicate() and Quad.getObject() are equal.

Implementations MUST also override Quad.hashCode() so that two equal Quads produce the same hash code.

Note that a Quad MUST NOT be equal to a Triple, even if this Quad's Quad.getGraphName() is Optional.empty(). To test triple-like equivalence, callers can use:

 Quad q1;
 Triple t2;
 q1.asTriple().equals(t2));
 

Specified by:

equals in interface Quad

Overrides:

equals in class java.lang.Object

Parameters:

obj - Another object

Returns:

true if other is a Quad and is equal to this

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Description copied from interface: Quad

Calculate a hash code for this Quad.

The returned hash code MUST be equal to the result of Objects.hash(Object...) with the arguments Quad.getSubject(), Quad.getPredicate(), Quad.getObject(), Quad.getGraphName().

This method MUST be implemented in conjunction with Quad.equals(Object) so that two equal Quads produce the same hash code.

Specified by:

hashCode in interface Quad

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this Quad.

Object.hashCode(), Objects.hash(Object...)
