                         java.lang.Long id)

Method Detail

clearAddedKeys

public void clearAddedKeys()

Clears the hash set of the added keys

clearDeletedKeys

public void clearDeletedKeys()

Clears the hash set of the deleted keys

forceRefresh

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

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

Throws:

java.lang.Exception

getAddedKeys

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

Gets a hash set of the added keys

getAttributes

public final java.lang.String getAttributes()

Returns a String of all the Key, Value Pairs.

getDeletedKeys

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

Gets a hash set of the deleted keys

getDeletedProperties

public java.util.List<java.lang.Object> getDeletedProperties(java.lang.String key)

Gets the value for the specified deleted keys

getFlag

public final OracleElementBase.FLAG getFlag()

graph

public org.apache.tinkerpop.gremlin.structure.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 org.apache.tinkerpop.gremlin.structure.Element

Returns:

a OraclePropertyGraph

id

public final java.lang.Object id()

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

Specified by:

id in interface org.apache.tinkerpop.gremlin.structure.Element

isPartial

public boolean isPartial()

Returns TRUE if this object is partially constructured. 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.

keys

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

Return all the keys associated with the element.

Specified by:

keys in interface org.apache.tinkerpop.gremlin.structure.Element

property

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

Assign a key/value property to the element.

Parameters:

key - key of the attribute (K/V)

value - value of the attribute (K/V)

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

property

public final void property(java.lang.String key,
                           java.lang.Object value,
                           boolean skipQueue,
                           boolean skipLucene)

Assign a key/value property to the element.

Parameters:

key - key of the attribute (K/V)

value - value of the attribute (K/V)

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

skipLucene - when true, then this K/V pair will not be indexed

propertyCommon

Assign a key/value property to the element.

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.

propertyValue

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

Return the value associated with the provided key.

refresh

public void refresh()

Re-read the attributes about this graph element from the database if this element is only partially constructed.

removeProperty

Set the flag denoting if the element is created with optimization flag

setFlag

public final void setFlag(OracleElementBase.FLAG f)

setGraph

public final void setGraph(OraclePropertyGraphBase opg)

Sets the property graph instance associated to this element

Parameters:

opg - a OraclePropertyGraph object

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.

Parameters:

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