Class ScriptInputFormat

java.lang.Object

<any>

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

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

All Implemented Interfaces:

GraphFilterAware, HadoopPoolsConfigurable

public final class ScriptInputFormat
extends CommonFileInputFormat

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.
