All Implemented Interfaces:

AutoCloseable

@PublicEvolving
public class StreamContextEnvironment
extends StreamExecutionEnvironment

Special StreamExecutionEnvironment that will be used in cases where the CLI client or testing utilities create a StreamExecutionEnvironment that should be used when StreamExecutionEnvironment.getExecutionEnvironment() is called.

Method Detail

execute

public JobExecutionResult execute(StreamGraph streamGraph)
                           throws Exception

Description copied from class: StreamExecutionEnvironment

Triggers the program execution. The environment will execute all parts of the program that have resulted in a "sink" operation. Sink operations are for example printing results or forwarding them to a message queue.

Overrides:

execute in class StreamExecutionEnvironment

Parameters:

streamGraph - the stream graph representing the transformations

Returns:

The result of the job execution, containing elapsed time and accumulators.

Throws:

Exception - which occurs during job execution.

executeAsync

public JobClient executeAsync(StreamGraph streamGraph)
                       throws Exception

Description copied from class: StreamExecutionEnvironment

Triggers the program execution asynchronously. The environment will execute all parts of the program that have resulted in a "sink" operation. Sink operations are for example printing results or forwarding them to a message queue.

Overrides:

executeAsync in class StreamExecutionEnvironment

Parameters:

streamGraph - the stream graph representing the transformations

Returns:

A JobClient that can be used to communicate with the submitted job, completed on submission succeeded.

Throws:

Exception - which occurs during job execution.

setAsContext

public static void setAsContext(PipelineExecutorServiceLoader executorServiceLoader,
                                Configuration clusterConfiguration,
                                ClassLoader userCodeClassLoader,
                                boolean enforceSingleJobExecution,
                                boolean suppressSysout)

unsetAsContext

public static void unsetAsContext()
