Method Detail

degree

public long degree(org.apache.tinkerpop.gremlin.structure.Direction direction,
                   java.lang.String... labels)

Get the vertex degree according to the provided direction and edge labels

Specified by:

degree in class OracleVertexBase

Parameters:

direction - the direction of the edges of the adjacent vertices

labels - the labels of the edges of the adjacent vertices

Returns:

vertex degree

edges

public java.util.Iterator<org.apache.tinkerpop.gremlin.structure.Edge> edges(org.apache.tinkerpop.gremlin.structure.Direction direction,
                                                                             OraclePropertyGraphBase.OptimizationFlag flag,
                                                                             java.lang.String... labels)

Return the edges incident to the vertex according to the given direction and edge labels. The information read back from the edges will be complete or partial based on the optimization flag specified.

Specified by:

edges in class OracleVertexBase

Parameters:

direction - the direction of the edges to retrieve

labels - the labels of the edges to retrieve

flag - an OptimizationFlag object specifying if a partial or complete vertex object will be returned. It can be NULL which implies the vertices created must be complete.

Returns:

an iterator of incident edges

getInstance

public static OracleVertex getInstance(OraclePropertyGraph opg,
                                       java.lang.Long vid)

Returns an instance of OracleVertex from the underlying graph

Parameters:

opg - the property graph where the OracleVertex instance will be obtained

vid - the id of the vertex

Returns:

a OracleVertex object.

getInstance

public static OracleVertex getInstance(OraclePropertyGraph opg,
                                       java.lang.Long vid,
                                       boolean bCreateIfAbsentFromCache)

Returns an instance of OracleVertex. If there is no match in the cache and bCreateIfAbsentFromCache is false, then a NULL value will be returned.

Parameters:

opg - the property graph where the OracleVertex instance will be obtained

vid - the id of the vertex

bCreateIfAbsentFromCache - if false, returns a NULL value if there is no match in the cache.

Returns:

a OracleVertex object.

getInstance

public static OracleVertex getInstance(OraclePropertyGraph opg,
                                       java.lang.Long vid,
                                       boolean bCreateIfAbsentFromCache,
                                       boolean bSkipStoreToCache)

Returns an instance of OracleVertex. If there is no match in the cache and bCreateIfAbsentFromCache is false, then a NULL value will be returned.If the skipStoreToCache is true, then the vertex will not be stored into the cache.

Parameters:

opg - the property graph where the OracleVertex instance will be obtained

vid - the id of the vertex

bCreateIfAbsentFromCache - if false, returns a NULL value if there is no match in the cache.

bSkipStoreToCache - if true, the vertex instance will not be stored into the cache.

Returns:

a OracleVertex object.
