forExecutable

@Nonnull
public static DefaultProcessExecutor forExecutable(@Nonnull
                                                   String executable)

Factory method for associating an executable. It returns an intermediate executor that must be configured and later started. Under Windows, the '.exe' suffix is automatically appended to the name of the executable.

Parameters:

executable - the executable (with the full path)

Returns:

the executor

withArgument

@Nonnull
public DefaultProcessExecutor withArgument(@Nonnull
                                           String argument)

Adds a single argument to pass to the external process.

Specified by:

withArgument in interface ProcessExecutor

Parameters:

argument - the argument

Returns:

itself for chaining methods

withArguments

@Nonnull
public DefaultProcessExecutor withArguments(@Nonnull
                                            String... arguments)

Adds some arguments to pass to the external process.

Specified by:

withArguments in interface ProcessExecutor

Parameters:

arguments - the arguments

Returns:

itself for chaining methods

start

@Nonnull
public DefaultProcessExecutor start()
                             throws IOException

Starts the external process.

Specified by:

start in interface ProcessExecutor

Returns:

itself for chaining methods

Throws:

IOException - in case of error

stop

public void stop()

Stops the external process.

Specified by:

waitForCompletion

@Nonnull
public DefaultProcessExecutor waitForCompletion()
                                         throws IOException,

Throws:

IOException - in case of I/O error

InterruptedException - if the wait has been interrupted

send

@Nonnull
public DefaultProcessExecutor send(@Nonnull
                                   String string)
