public final class Step
extends com.google.api.client.json.GenericJson
Defines a particular step within a Cloud Dataflow job. A job consists of multiple steps, each of
 which performs some specific operation as part of the overall job. Data is typically passed from
 one step to another as part of the job. **Note:** The properties of this object are not stable
 and might change. Here's an example of a sequence of steps which together implement a Map-Reduce
 job: * Read a collection of data from some source, parsing the collection's elements. * Validate
 the elements. * Apply a user-defined function to map each element to some value and extract an
 element-specific key value. * Group elements with the same key into a single element with that
 key, transforming a multiply-keyed collection into a uniquely-keyed collection. * Write the
 elements out to some data sink. Note that the Cloud Dataflow service may be used to run many
 different types of jobs, not just Map-Reduce.

 
 This is the Java data model class that specifies how to parse/serialize into the JSON that is
 transmitted over HTTP when working with the Dataflow API. For a detailed explanation see:

Method Detail





getKind
public String getKind()
The kind of step in the Cloud Dataflow job.

Returns:
value or null for none








setKind
public Step setKind(String kind)
The kind of step in the Cloud Dataflow job.

Parameters:
kind - kind or null for none








getName
public String getName()
The name that identifies the step. This must be unique for each step with respect to all other
 steps in the Cloud Dataflow job.

Returns:
value or null for none








setName
public Step setName(String name)
The name that identifies the step. This must be unique for each step with respect to all other
 steps in the Cloud Dataflow job.

Parameters:
name - name or null for none








getProperties
public Map<String,Object> getProperties()
Named properties associated with the step. Each kind of predefined step has its own required
 set of properties. Must be provided on Create. Only retrieved with JOB_VIEW_ALL.

Returns:
value or null for none








setProperties
public Step setProperties(Map<String,Object> properties)
Named properties associated with the step. Each kind of predefined step has its own required
 set of properties. Must be provided on Create. Only retrieved with JOB_VIEW_ALL.

Parameters:
properties - properties or null for none








set
public Step set(String fieldName,
                Object value)

Overrides:
set in class com.google.api.client.json.GenericJson








clone
public Step clone()

Overrides:
clone in class com.google.api.client.json.GenericJson
