Description copied from class: CommonOLAP

Store persistentProperties and any hard coded fields in an apache config object for propagation to spark executors.

Specified by:

storeState in interface org.apache.tinkerpop.gremlin.process.computer.VertexProgram<String>

Overrides:

storeState in class GraknVertexProgram<String>

Parameters:

configuration - the apache config object that will be propagated

loadState

                      org.apache.commons.configuration.Configuration configuration)

Description copied from class: CommonOLAP

Load persistentProperties and any hard coded fields from an apache config object for use by the spark executor.

Specified by:

loadState in interface org.apache.tinkerpop.gremlin.process.computer.VertexProgram<String>

Overrides:

loadState in class CommonOLAP

Parameters:

graph - the tinker graph

configuration - the apache config object containing the values
