Method Detail

execute

public ExecutorTask execute(ExecInfo info)
                     throws IOException

Description copied from class: Executor

Execute a class given by name with some arguments in this executor.

Overrides:

execute in class Executor

Following copied from class: org.openide.execution.Executor

Parameters:

info - information describing what to execute

Returns:

a task object that can be used to control the running process

Throws:

IOException - if the execution cannot be started (class is missing, etc.)

getHelpCtx

public HelpCtx getHelpCtx()

Description copied from class: ServiceType

Get context help for this service type.

Overrides:

getHelpCtx in class Executor

Following copied from class: org.openide.ServiceType

Returns:

context help

checkClass

protected void checkClass(Class clazz)
                   throws IOException

Subclasses of the executor can override this method to check loaded class before its main method is invoked.

Parameters:

clazz -

Throws:

IOException -

executeClass

protected void executeClass(Class clazz,
                            String[] params)

Invokes main method of the class with given parameters.

Parameters:

clazz -

params -

createClassLoader

protected ClassLoader createClassLoader(InputOutput io)

Allows subclasses to provide its own classloader for loading classes. Because the class loader is responsible for redirection of input and output this method takes input output where the I/O should be printed.

Default implementation creates new NbClassLoader (io)

Parameters:

io - the input/output to sent output of the classes to

Returns:

the class loader to use
