Method Details

setup

public void setup()

Sets up plugins. Non-static so that loading is inherited.

redirectIO

private static void redirectIO(InputStream src,
 PrintStream dest,
 Consumer<String> cons)

Redirects an input stream to another stream (in parallel).

Parameters:

src - the source stream

dest - the destination stream

cons - optional consumer to analyze received lines, may be null for none

createPythonProcess

public static Process createPythonProcess(File dir,
 String... args)
                                   throws IOException

Creates and starts a Python process.

Parameters:

dir - the home dir where to find the script/run it within

args - the process arguments for the script including python arguments (first), script and script arguments

Returns:

the created process

Throws:

IOException - if process creation fails

createPythonProcess

public static Process createPythonProcess(File dir,
 Consumer<String> stdCons,
 Consumer<String> errCons,
 String... args)
                                   throws IOException

Creates and starts a Python process.

Parameters:

dir - the home dir where to find the script/run it within

stdCons - optional consumer on standard out, may be null

errCons - optional consumer on standard error, may be null

args - the process arguments for the script including python arguments (first), script and script arguments

Returns:

the created process

Throws:

IOException - if process creation fails

createPythonProcess

public static Process createPythonProcess(String... args)
                                   throws IOException

Creates and starts a Python process with home directory "./src/test/python".

Parameters:

args - the process arguments for the script including python arguments (first), script and script arguments

Returns:

the created process

Throws:

IOException - if process creation fails

createPythonProcess

public static Process createPythonProcess(Consumer<String> stdCons,

Parameters:

stdCons - optional consumer on standard out, may be null

errCons - optional consumer on standard error, may be null

args - the process arguments for the script including python arguments (first), script and script arguments

Returns:

the created process

Throws:

IOException - if process creation fails
