Method Detail

forceRefresh

public abstract void forceRefresh()
                           throws java.lang.Exception

Re-read the attributes about this graph element from the database.

Specified by:

forceRefresh in interface OracleElementBase

Throws:

java.lang.Exception

getAttributes

public java.lang.String getAttributes()

Returns a String of all the Key, Value Pairs.

Specified by:

getAttributes in interface OracleElementBase

getId

public java.lang.Long getId()

An identifier that is unique to its inheriting class.

getProperty

public java.lang.Object getProperty(java.lang.String key)

Return the object value associated with the provided string key.

getPropertyGraph

public OraclePropertyGraph getPropertyGraph()

Gets the property graph instance associated to this vertex

Returns:

a OraclePropertyGraph object

getPropertyKeys

public java.util.Set<java.lang.String> getPropertyKeys()

graph

public com.tinkerpop.blueprints.Graph graph()

Gets the property graph instance associated to this object. All the changes done to this object will be committed once the commit operation is executed for this property graph.

Specified by:

graph in interface Element

Returns:

a OraclePropertyGraph

id

public java.lang.Object id()

Returns an identifier of this element that is unique to its inheriting class.

Specified by:

id in interface Element

isPartial

public boolean isPartial()

Returns TRUE if this object is partially constructed. For example, a vertex with just an ID but not the K/V pairs. Or an edge with just an ID but not the in/out vertices or edge label.

refresh

public void refresh()

removeProperty

public java.lang.Object removeProperty(java.lang.String key)

Un-assigns a key/value property from the element.

setPartial

public void setPartial(boolean partial)

Set a flag to denote if this graph element is only partially constructed. For example, a vertex with just an ID but not the K/V pairs. Or an edge with just an ID but not the in/out vertices or edge label.

Specified by:

setPartial in interface OracleElementBase

Parameters:

partial - true if this graph element is only partially constructed.

setProperty

public void setProperty(java.lang.String key,
                        java.lang.Object value)

Assign a key/value property to the element.

setProperty

public void setProperty(java.lang.String key,
                        java.lang.Object value,
                        boolean skipQueue)

Assign a key/value property to the element.

Specified by:

setProperty in interface OracleElementBase

Parameters:

key - key of an attribute (K/V pair)

value - value of an attribute (K/V pair)

skipQueue - when true, then this K/V pair change will not cause this Element to be put in the update queye.
