Method Detail

key

public 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

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

toString

public String toString()

Overrides:

toString in class Object

id

public Object id()

Description copied from interface: Element

Gets the unique identifier for the graph Element.

Specified by:

id in interface Element

Overrides:

id in class TinkerElement

Returns:

The id of the element

equals

public boolean equals(Object object)

Overrides:

equals in class TinkerElement

keys

public Set<String> keys()

Description copied from interface: Element

Get the keys of the properties associated with this element. The default implementation iterators the properties and stores the keys into a HashSet.

Specified by:

keys in interface Element

Returns:

property

public <U> Property<U> property(String key)

Description copied from interface: Element

Get a Property for the Element given its key. The default implementation calls the raw Element.properties(java.lang.String...).

Specified by:

property in interface Element

property

public <U> Property<U> property(String key,
                                U value)

Description copied from interface: Element

Add or set a property value for the Element given its key.

Specified by:

property in interface Element

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: Property

Remove the property from the associated element.

Specified by:

remove in interface Element

Specified by:

remove in interface Property<V>

properties

public <U> Iterator<Property<U>> properties(String... propertyKeys)

Description copied from interface: VertexProperty

Get an Iterator of properties.

Specified by:

properties in interface Element

Specified by:

properties in interface VertexProperty<V>
