extends java.lang.Object

Result is the data structure which contains the returned result(s) of a task execution.

Field Summary

long	argumentPosition When the results are intermediate, this field specifies which input argument (of the destination task) must be set.
Sequence	computedBy This field keeps track of the task that produced the results.
TaskInfo	destinationTaskInfo When the results are not final, this field keeps information about the destination task, i.e.
long	jobId The Id of the current job
java.lang.Object	results The actual results are stored here.

Constructor Summary

Result(Result copyResult)
Use this constructor when you want to replicate a "result" object.

Result(TaskInfo taskInfo, Sequence computedBy, long argPos, java.lang.Object result)
Use this constructor when you want to create a Result object form scratch

Field Detail

argumentPosition

public long argumentPosition

When the results are intermediate, this field specifies which input argument (of the destination task) must be set.

computedBy

public Sequence computedBy

This field keeps track of the task that produced the results. This information can be used for statistical reasons, and helps us NOT to execute the same task twice.

destinationTaskInfo

public TaskInfo destinationTaskInfo

When the results are not final, this field keeps information about the destination task, i.e. the task which will receive as input argument those results.

jobId

public long jobId

The Id of the current job

results

public java.lang.Object results

The actual results are stored here. Even though they appear as type "Object", in reality they are treated as an array of type "Object".
