Package org.apache.tinkerpop.gremlin.process.traversal

Class NotP<V>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.P<V>

org.apache.tinkerpop.gremlin.process.traversal.NotP<V>

All Implemented Interfaces:

Serializable, Cloneable, Predicate<V>

public class NotP<V>
extends P<V>

A NotP wraps a P and represents its negation. This class provides the logical NOT operation for predicates, inverting the result of the wrapped predicate's test method.

Method Summary

Modifier and Type	Method	Description
P<V>	clone()
V	getValue()	Gets the current value to be passed to the predicate for testing.
P<V>	getWrapped()	Returns the inner predicate wrapped by this NotP.
boolean	hasTraversal()	Determines if this predicate holds a child traversal whose result is resolved at runtime.
boolean	isResolvedEmpty()	Returns true if the most recent call to P.resolve(Traverser.Admin) produced no results for a scalar predicate, meaning there is no meaningful comparison value.
P<V>	negate()	Returns the original unwrapped P, since double negation cancels out.
void	resolve(Traverser.Admin<?> traverser)	Resolves the child traversal(s) against the given traverser, replacing the traversal value with the resolved literal(s) for this test cycle.
void	setValue(V value)
String	toString()

Method Details

getValue

public V getValue()

Gets the current value to be passed to the predicate for testing.

Overrides:

getValue in class P<V>

setValue

public void setValue(V value)

Overrides:

setValue in class P<V>

toString

public String toString()

Overrides:

toString in class P<V>

getWrapped

public P<V> getWrapped()

Returns the inner predicate wrapped by this NotP.

negate

public P<V> negate()

Returns the original unwrapped P, since double negation cancels out.

Specified by:

negate in interface Predicate<V>

Overrides:

negate in class P<V>

clone

public P<V> clone()

Overrides:

clone in class P<V>

hasTraversal

public boolean hasTraversal()

Description copied from class: P

Determines if this predicate holds a child traversal whose result is resolved at runtime.

Overrides:

hasTraversal in class P<V>

isResolvedEmpty

public boolean isResolvedEmpty()

Description copied from class: P

Returns true if the most recent call to P.resolve(Traverser.Admin) produced no results for a scalar predicate, meaning there is no meaningful comparison value.

Overrides:

isResolvedEmpty in class P<V>

resolve

public void resolve(Traverser.Admin<?> traverser)

Description copied from class: P

Resolves the child traversal(s) against the given traverser, replacing the traversal value with the resolved literal(s) for this test cycle. If no traversal is present, this method returns immediately.

Overrides:

resolve in class P<V>
