Constructors

Constructor and Description
TinkerVertexProperty(Object id, TinkerVertex vertex, String key, V value, Object... propertyKeyValues) Use this constructor to construct VertexProperty instances for TinkerGraph where the id can be explicitly set and validated against the expected data type.
TinkerVertexProperty(TinkerVertex vertex, String key, V value, Object... propertyKeyValues) This constructor will not validate the ID type against the Graph.

Constructor Detail

TinkerVertexProperty

public TinkerVertexProperty(TinkerVertex vertex,
                            String key,
                            V value,
                            Object... propertyKeyValues)

This constructor will not validate the ID type against the Graph. It will always just use a Long for its identifier. This is useful for constructing a VertexProperty for usage with TinkerGraphComputerView.

TinkerVertexProperty

public TinkerVertexProperty(Object id,
                            TinkerVertex vertex,
                            String key,
                            V value,
                            Object... propertyKeyValues)

Use this constructor to construct VertexProperty instances for TinkerGraph where the id can be explicitly set and validated against the expected data type.

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:

The property key set

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>
