forceRefresh

public abstract void forceRefresh()
                           throws Exception

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

Specified by:

forceRefresh in interface OracleElementBase

Throws:

Exception

getAttributes

public String getAttributes()

Returns a String of all the Key, Value Pairs.

getId

public Long getId()

Return the identifier of this element.

Specified by:

getId in interface Element

getProperty

public Object getProperty(String key)

Return the value associated with the provided key.

Specified by:

getProperty in interface Element

getPropertyGraph

public OraclePropertyGraph getPropertyGraph()

Gets the property graph instance associated to this element

Returns:

a OraclePropertyGraph object

getPropertyKeys

public Set<String> getPropertyKeys()

Return all the keys associated with the element.

Specified by:

getPropertyKeys in interface 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.

refresh

public void refresh()

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

removeProperty

public Object removeProperty(String key)

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

Specified by:

removeProperty in interface 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(String key,
               Object value)

Assign a key/value property to the element.

Specified by:

setProperty in interface Element

setProperty

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

Assign a key/value property to the element.

Specified by:

setProperty in interface OracleElementBase

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.

setProperty

public void setProperty(String key,
               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

setPropertyCommon

public void setPropertyCommon(String key,
                     Object value,
                     boolean skipQueue)

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.
