 Job job)

Method Details

getPlatform

public JavaPlatform getPlatform()

Returns:

the Platform this instance belongs to

execute

protected Tuple<List<ChannelInstance>,PartialExecution> execute(ExecutionTask task,
 List<ChannelInstance> inputChannelInstances,
 OptimizationContext.OperatorContext producerOperatorContext,
 boolean isRequestEagerExecution)

Description copied from class: PushExecutorTemplate

Executes the given task and return the output ChannelInstances.

Specified by:

execute in class PushExecutorTemplate

Parameters:

task - that should be executed

inputChannelInstances - inputs into the task

isRequestEagerExecution - whether the ExecutionTask should be executed eagerly if possible

Returns:

the ChannelInstances created as output of task

openFunction

public static void openFunction(JavaExecutionOperator operator,
 Object function,
 ChannelInstance[] inputs,
 OptimizationContext.OperatorContext operatorContext)

Utility function to open an ExtendedFunction.

Parameters:

operator - the JavaExecutionOperator containing the function

function - the ExtendedFunction; if it is of a different type, nothing happens

inputs - the input ChannelInstances for the operator

operatorContext - context information for the operator

getCompiler

public FunctionCompiler getCompiler()
