Method Detail

isPresent

public boolean isPresent()

Description copied from interface: Property

Whether the property is empty or not.

Specified by:

isPresent in interface Property<V>

Returns:

True if the property exists, else false

key

public java.lang.String key()

Description copied from interface: Property

The key of the property.

Specified by:

key in interface Property<V>

Returns:

The property key

value

public V value()

Description copied from interface: Property

The value of the property.

Specified by:

value in interface Property<V>

Returns:

The property value

element

public Vertex element()

Description copied from interface: VertexProperty

Gets the Vertex that owns this VertexProperty.

Specified by:

element in interface Property<V>

Specified by:

element in interface VertexProperty<V>

Returns:

The element associated with this property (i.e. Vertex, Edge, or VertexProperty).

remove

public void remove()

Description copied from interface: Element

Removes the Element from the graph.

Specified by:

remove in interface Element

Specified by:

remove in interface Property<V>

Overrides:

remove in class DetachedElement<Property<V>>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object object)

Overrides:

equals in class DetachedElement<Property<V>>

attach

public VertexProperty<V> attach(Vertex hostVertex)

Specified by:

attach in interface Attachable<Property<V>>

attach

public VertexProperty<V> attach(Graph hostGraph)

Specified by:

attach in interface Attachable<Property<V>>

iterators

public VertexProperty.Iterators iterators()

Description copied from interface: Element

Gets the iterators for the Element. Iterators provide low-level access to the data associated with an Element as they do not come with the overhead of Traversal construction. Use iterators in places where performance is most crucial.

Specified by:

iterators in interface Element

Specified by:

iterators in interface VertexProperty<V>

Overrides:

iterators in class DetachedElement<Property<V>>

propertyIterator

public <U> java.util.Iterator<Property<U>> propertyIterator(java.lang.String... propertyKeys)

Description copied from interface: Element.Iterators

Get an Iterator of properties.

Specified by:

propertyIterator in interface Element.Iterators

Specified by:

propertyIterator in interface VertexProperty.Iterators

Overrides:

propertyIterator in class DetachedElement<Property<V>>
