JMadKernel (jmad-core API)

All Known Implementing Classes:

JMadKernelImpl
```
public interface JMadKernel
```
this is the interface for central class which controls an instance of MadX. The kernel only is able to do the most primitives tasks: start the MadX-process, stop it and send commands to it. Furthermore it takes care of the logging of input and output of the MadX process. Listeners can also be attached, which then get notified, when the status of the kernel changes.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addListener(JMadKernelListener listener)`
`Result`	`execute(JMadExecutable executable)`	executes a Command or Task, waits for completion (our timeout if set), and returns result, if command/task provides one.
`java.io.File`	`getOutputFile()`
`boolean`	`isMadxRunning()`
`void`	`removeListener(JMadKernelListener listener)`
`void`	`start()`	starts madx as a separate thread and configures the needed streams.
`int`	`stop()`	stops the madx-thread

- Method Detail
  - start
```
void start()
    throws JMadException
```
    starts madx as a separate thread and configures the needed streams.
    
    Throws:
    
    JMadException - if the starting of the MadX process fails
  - stop
```
int stop()
  throws JMadException
```
    stops the madx-thread
    
    Returns:
    
    the exit-value of madx
    
    Throws:
    
    JMadException - if the stopping of the MadX process fails
  - execute
```
Result execute(JMadExecutable executable)
        throws JMadException
```
    executes a Command or Task, waits for completion (our timeout if set), and returns result, if command/task provides one.
    
    Parameters:
    
    executable - the command or task to execute
    
    Returns:
    
    the result, if available, otherwise null
    
    Throws:
    
    JMadException - if the execution fails
  - isMadxRunning
```
boolean isMadxRunning()
```
    Returns:
    
    true, if madx was started before, false otherwise
  - addListener
```
void addListener(JMadKernelListener listener)
```
    Parameters:
    
    listener - the listener to add
  - removeListener
```
void removeListener(JMadKernelListener listener)
```
    Parameters:
    
    listener - the listener to remove
  - getOutputFile
```
java.io.File getOutputFile()
```
    Returns:
    
    the JMadKernel OutputFile
