|---|---|
Vertex |
addVertex(Object... keyValues)
Add a
Vertex to the graph given an optional series of key/value pairs. |
void |
close()
Closing a
Graph is equivalent to "shutdown" and implies that no futher operations can be executed on
the instance. |
GraphComputer |
compute()
Generate a
GraphComputer using the default engine of the underlying graph system. |
<C extends GraphComputer> |
compute(Class<C> graphComputerClass)
Declare the
GraphComputer to use for OLAP operations on the graph. |
Configuration |
configuration()
Get the
org.apache.commons.configuration.Configuration associated with the construction of this graph. |
Iterator<Edge> |
edges(Object... edgeIds)
Get the
Edge objects in this graph with the provided edge ids. |

Transaction |
tx()
Configure and control the transactions for those graphs that support this feature.

A collection of global
Graph.Variables associated with the graph. |

public <C extends GraphComputer> C compute(Class<C> graphComputerClass) throws IllegalArgumentException
GraphGraphComputer to use for OLAP operations on the graph.
If the graph does not support graph computer then an UnsupportedOperationException is thrown.compute in interface GraphgraphComputerClass - The graph computer class to use.IllegalArgumentException - if the provided GraphComputer class is not supported.public GraphComputer compute() throws IllegalArgumentException
GraphGraphComputer using the default engine of the underlying graph system.
This is a shorthand method for the more involved method that uses Graph.compute(Class).compute in interface GraphIllegalArgumentException - if there is no default graph computerpublic Iterator<Vertex> vertices(Object... vertexIds)
GraphVertex objects in this graph with the provided vertex ids. If no ids are provided, get all
vertices. Note that a vertex identifier does not need to correspond to the actual id used in the graph. It
needs to be a bit more flexible than that in that given the Graph.Features around id support, multiple
arguments might be applicable here.
If the graph return true for Graph.Features.ElementFeatures.supportsNumericIds() then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsCustomIds() ()} then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsAnyIds() ()} then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsStringIds() ()} then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsStringIds() ()} then it should support
filters as with:
public Iterator<Edge> edges(Object... edgeIds)
GraphEdge objects in this graph with the provided edge ids. If no ids are provided, get all edges.
Note that an edge identifier does not need to correspond to the actual id used in the graph. It
needs to be a bit more flexible than that in that given the Graph.Features around id support, multiple
arguments might be applicable here.
If the graph return true for Graph.Features.ElementFeatures.supportsNumericIds() then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsCustomIds() ()} then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsAnyIds() ()} then it should support
filters as with:
true for Graph.Features.ElementFeatures.supportsStringIds() ()} then it should support
filters as with:
public Transaction tx()
GraphTransaction in the TinkerPop context is a
transaction "factory" or "controller" that helps manage transactions owned by the underlying graph database.public Graph.Variables variables()
GraphGraph.Variables associated with the graph.
Variables are used for storing metadata about the graph.public Configuration configuration()
Graphorg.apache.commons.configuration.Configuration associated with the construction of this graph.
Whatever configuration was passed to GraphFactory#open(org.apache.commons.configuration.Configuration)
is what should be returned by this method.configuration in interface Graphpublic void close()
throws Exception
GraphGraph is equivalent to "shutdown" and implies that no futher operations can be executed on
the instance. Users should consult the documentation of the underlying graph database implementation for what
this "shutdown" will mean as it pertains to open transactions. It will typically be the end user's
responsibility to synchronize the thread that calls close() with other threads that are accessing open
transactions. In other words, be sure that all work performed on the Graph instance is complete prior
to calling this method.close in interface AutoCloseableclose in interface GraphExceptionCopyright © 2013–2015 Apache Software Foundation. All rights reserved.
