Class ScriptOutputFormat

java.lang.Object

<any>

org.apache.tinkerpop.gremlin.hadoop.structure.io.CommonFileOutputFormat

org.apache.tinkerpop.gremlin.hadoop.structure.io.script.ScriptOutputFormat

All Implemented Interfaces:

PersistResultGraphAware, HadoopPoolsConfigurable

public final class ScriptOutputFormat
extends CommonFileOutputFormat
implements HadoopPoolsConfigurable

ScriptInputFormat and ScriptOutputFormat take an arbitrary script and use that script to either read or write Vertex objects, respectively. This can be considered the most general InputFormat/OutputFormat possible in that Hadoop-Gremlin uses the user provided script for all reading/writing.
