Class ScriptInputFormat

java.lang.Object

<any>

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

All Implemented Interfaces:

HadoopPoolsConfigurable

public final class ScriptInputFormat
extends <any>
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.
