Method Detail

doCreateRunOnceTasks

protected java.util.List<Task> doCreateRunOnceTasks(java.util.Map<java.lang.String,Bucket> inputBuckets,
                                                    java.util.Map<java.lang.String,Bucket> outputBuckets,
                                                    AnyMap parameters,
                                                    java.lang.String workerName)

Creates a list of tasks for given input buckets. One task will be generated for each input bucket and in the store an empty bulk object will be created.

Overrides:

doCreateRunOnceTasks in class DefaultTaskGenerator

Parameters:

inputBuckets - key: input slot name, value: bucket for this slot

outputBuckets - key: output slot name, value: bucket for this slot

parameters - key: param name, value: (evaluated) param value

workerName - (action) worker for which to create new tasks

Returns:

a list of new generated tasks

createRunOnceTasks

public java.util.List<Task> createRunOnceTasks(java.util.Map<java.lang.String,Bucket> inputBuckets,
                                               java.util.Map<java.lang.String,Bucket> outputBuckets,
                                               AnyMap parameters,
                                               java.lang.String workerName)
                                        throws TaskGeneratorException

Creates tasks for the RunOnce mode, i.e. for all objects in the input bucket of the start action.

Note: The method will create one task per object in the input bucket. If there is more than one input bucket defined for the worker, a TaskGeneratorException will be thrown.

. But there is no check for the number of buckets.

Specified by:

createRunOnceTasks in interface TaskGenerator

Overrides:

createRunOnceTasks in class DefaultTaskGenerator

Parameters:

inputBuckets - key: input slot name, value: bucket for this slot

outputBuckets - key: output slot name, value: bucket for this slot

parameters - key: param name, value: (evaluated) param value

workerName - (action) worker for which to create new tasks

Returns:

a list of new generated tasks

Throws:

TaskGeneratorException - error while generating tasks
