public final class Source extends GenericJson
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 Google Dataflow API. For a detailed explanation see: http://code.google.com/p/google-http-java-client/wiki/JSON

Modifier and Type | Method and Description |
---|---|
Source |
clone() |
List<Map<String,Object>> |
getBaseSpecs()
While splitting, sources may specify the produced bundles as differences against another
source, in order to save backend-side memory and allow bigger jobs.
|
Map<String,Object> |
getCodec()
The codec to use to decode data read from the source.
|
Boolean |
getDoesNotNeedSplitting()
Setting this value to true hints to the framework that the source doesn't need splitting, and
using SourceSplitRequest on it would yield SOURCE_SPLIT_OUTCOME_USE_CURRENT.
|
SourceMetadata |
getMetadata()
Optionally, metadata for this source can be supplied right away, avoiding a
SourceGetMetadataOperation roundtrip (see SourceOperationRequest).
|
Map<String,Object> |
getSpec()
The source to read from, plus its parameters.
|
Source |
set(String fieldName,
Object value) |
Source |
setBaseSpecs(List<Map<String,Object>> baseSpecs)
While splitting, sources may specify the produced bundles as differences against another
source, in order to save backend-side memory and allow bigger jobs.
|
Source |
setCodec(Map<String,Object> codec)
The codec to use to decode data read from the source.
|
Source |
setDoesNotNeedSplitting(Boolean doesNotNeedSplitting)
Setting this value to true hints to the framework that the source doesn't need splitting, and
using SourceSplitRequest on it would yield SOURCE_SPLIT_OUTCOME_USE_CURRENT.
|
Source |
setMetadata(SourceMetadata metadata)
Optionally, metadata for this source can be supplied right away, avoiding a
SourceGetMetadataOperation roundtrip (see SourceOperationRequest).
|
Source |
setSpec(Map<String,Object> spec)
The source to read from, plus its parameters.
