ComputerElement

public ComputerElement(Element element)

Method Detail

id

public Object id()

Description copied from interface: Element

Gets the unique identifier for the graph Element.

Specified by:

id in interface Element

Returns:

The id of the element

label

public String label()

Description copied from interface: Element

Gets the label for the graph Element which helps categorize it.

Specified by:

label in interface Element

Returns:

The label of the element

graph

public Graph graph()

Description copied from interface: Element

Get the graph that this element is within.

Specified by:

graph in interface Element

Returns:

the graph of this element

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 <V> Property<V> 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 <V> Property<V> property(String key,
                                V value)

Description copied from interface: Element

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

Specified by:

property in interface Element

value

public <V> V value(String key)
            throws NoSuchElementException

Description copied from interface: Element

Get the value of a Property given it's key. The default implementation calls Element.property(java.lang.String) and then returns the associated value.

Specified by:

value in interface Element

Throws:

NoSuchElementException - if the property does not exist on the Element.

remove

public void remove()

Description copied from interface: Element

Removes the Element from the graph.

Specified by:

remove in interface Element

properties

public <V> Iterator<? extends Property<V>> properties(String... propertyKeys)

Description copied from interface: Element

Get an Iterator of properties where the propertyKeys is meant to be a filter on the available keys. If no keys are provide then return all the properties.

Specified by:

properties in interface Element

values

public <V> Iterator<V> values(String... propertyKeys)

Description copied from interface: Element

Get the values of properties as an Iterator.

Specified by:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object other)

Overrides:
