TaskResult (scheduling 14.1.0-SNAPSHOT API)

All Superinterfaces:

Serializable

All Known Implementing Classes:

TaskResultImpl, TaskResultImpl
```
@PublicAPI
public interface TaskResult
extends Serializable
```
Interface representing the task result.
A task result can be an exception or a serializable object that you have to cast into your own type.
Before getting the object it is recommended to call the hadException() method.
It will tell you if an exception occurred in the task that generate this result.

Since:

ProActive Scheduling 0.9

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`FlowAction`	`getAction()` If a FlowScript was executed on this task, its result is stored it so that the action can be performed later when processed by the core.
`Throwable`	`getException()` Retrieve the exception threw by the task.
`Map<String,String>`	`getMetadata()` Get metadata associated with this result.
`TaskLogs`	`getOutput()` Return the output of the execution, including stdout and stderr.
`Map<String,byte[]>`	`getPropagatedVariables()` Return the content of propagated variables, in byte array format
`Map<String,Serializable>`	`getResultMap()` Returns a map of job results
`byte[]`	`getSerializedValue()` Get the serialized value of the task.
`TaskId`	`getTaskId()` To get the id of the task.
`Serializable`	`getValue()` Get the value of the task.
`Map<String,Serializable>`	`getVariables()` Returns the deserialized version of the propagated variables
`boolean`	`hadException()` To know if an exception has occurred on this task.
`boolean`	`isRaw()` Returns true if this result contains raw data (i.e.
`Serializable`	`value()` Get the value of the task.

- Method Detail
  - hadException
```
boolean hadException()
```
    To know if an exception has occurred on this task.
    
    Returns:
    
    true if an exception occurred, false if not.
  - getTaskId
```
TaskId getTaskId()
```
    To get the id of the task.
    
    Returns:
    
    the id of the task.
  - value
```
Serializable value()
            throws Throwable
```
    Get the value of the task. Throw the exception if the task generate
    
    Returns:
    
    the value of the task.
    
    Throws:
    
    Throwable - If the value has generate an exception.
  - getValue
```
Serializable getValue()
               throws Throwable
```
    Get the value of the task. Returns null if an exception occurred during the task execution
    
    Returns:
    
    the value of the task.
    
    Throws:
    
    Throwable
  - getSerializedValue
```
byte[] getSerializedValue()
```
    Get the serialized value of the task.
    
    Returns:
    
    the value of the task, null if an exception occurred.
  - getMetadata
```
Map<String,String> getMetadata()
```
    Get metadata associated with this result. Metadata let the task add additional information bound to the result. It is the responsibility of the business-code to define the metadata semantics. For example, if the result contains binary data, the metadata map could contain the binary content type, or the name of the file if the result needs to be written on disk.
    
    Returns:
    
    a map of metadata
  - getAction
```
FlowAction getAction()
```
    If a FlowScript was executed on this task, its result is stored it so that the action can be performed later when processed by the core.
    
    Returns:
    
    the Control Flow action embedded in this TaskResult
  - getException
```
Throwable getException()
```
    Retrieve the exception threw by the task. If the task didn't throw an exception, null is returned
    
    Returns:
    
    the exception threw by the task.
  - getOutput
```
TaskLogs getOutput()
```
    Return the output of the execution, including stdout and stderr.
    
    Returns:
    
    the output of the execution, including stdout and stderr.
  - getPropagatedVariables
```
Map<String,byte[]> getPropagatedVariables()
```
    Return the content of propagated variables, in byte array format
    
    Returns:
    
    a map of byte arrays
  - getVariables
```
Map<String,Serializable> getVariables()
                               throws IOException,
                                      ClassNotFoundException
```
    Returns the deserialized version of the propagated variables
    
    Returns:
    
    a map of variables
    
    Throws:
    
    IOException
    
    ClassNotFoundException
  - isRaw
```
boolean isRaw()
```
    Returns true if this result contains raw data (i.e. a byte array) instead of an object
    
    Returns:
    
    result object type
  - getResultMap
```
Map<String,Serializable> getResultMap()
```
    Returns a map of job results
    
    Returns:
    
    merged map of job results
