All Implemented Interfaces:

com.tinkerpop.blueprints.Graph, com.tinkerpop.blueprints.IndexableGraph, com.tinkerpop.blueprints.KeyIndexableGraph, com.tinkerpop.blueprints.TransactionalGraph, MesgConsts
```
public class OraclePropertyGraph
extends OraclePropertyGraphBase
```
This class implements the Blueprints Graph interface on top an Apache HBase backend database. Note that this implementation is not thread safe. To safely perform concurrent operations against a single graph, multiple instances of OraclePropertyGraph are recommended.

```
    Gets an array of Iterable objects that hold all the edges in the graph that satisfy the specified edge filter callback. The information read back from the edges will be complete or partial based on the optimization flag specified. Each element in the Iterable array uses a separate connection provided to fetch a subset of the results from the corresponding split. The splits are determined by # of regions & num of splits per region for the table. Note that we assign an integer ID (in the range of [0, N - 1]) to all the splits in the vertex table with N splits. The subset of splits queried will consist of those splits with ID value in the range of [startSplitID, startSplit - 1 + size of connections array].
    
    Parameters:
    
    connections - an array of connections to Apache HBase.
    
    bSkipStoreToCache - if true, the edges instances will not be stored into the cache.
    
    flag - an OptimizationFlag object specifying if a partial or complete edge object will be returned. It can be NULL which implies the edges created must be complete.
    
    startSplitID - the ID of the starting split.
    
    efc - a EdgeFilterCallback object specifying the conditions to keep an edge in the Iterable.
    
    Returns:
    
    an Iterable array object.

    Gets an array of Iterable objects that hold all the vertices in the graph that have a particular key. Each element in the Iterable array uses a separate connection provided to fetch a subset of the results from the corresponding split. The splits are determined by # of regions & num of splits per region for the table. Note that we assign an integer ID (in the range of [0, N - 1]) to all the splits in the vertex table with N splits. The subset of splits queried will consist of those splits with ID value in the range of [startSplitID, startSplit - 1 + size of connections array].
    
    Parameters:
    
    connections - an array of connections to Apache HBase.
    
    bSkipStoreToCache - if true, the vertices instances will not be stored into the cache.
    
    startSplitID - the ID of the starting split.
    
    key - name of the property. It can be NULL which implies all vertices in the graph will be returned.
    
    bCloneGraph - if true, each Iterable in the array will use a new OraclePropertyGraph instance behind the scenes. If there are writing operations done over the retrieved vertices, the associated property graphs need to be commited for the changes to be persisted into Apache HBase.
    
    Returns:
    
    an Iterable array object.

```
    Gets an array of Iterable objects that hold all the vertices in the graph that satisfy the specified vertex filter callback. The information read back from the vertices will be complete or partial based on the optimization flag specified. Each element in the Iterable array uses a separate connection provided to fetch a subset of the results from the corresponding split. The splits are determined by # of regions & num of splits per region for the table. Note that we assign an integer ID (in the range of [0, N - 1]) to all the splits in the vertex table with N splits. The subset of splits queried will consist of those splits with ID value in the range of [startSplitID, startSplit - 1 + size of connections array].
    
    Parameters:
    
    connections - an array of connections to Apache HBase.
    
    bSkipStoreToCache - if true, the vertices instances will not be stored into the cache.
    
    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.
    
    startSplitID - the ID of the starting split.
    
    vfc - a VertexFilterCallback object specifying the conditions to keep an vertex in the Iterable.
    
    Returns:
