Method Details

invokeProcess

public static int invokeProcess(String[] commandLine)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Discards any output of the process.

Parameters:

commandLine - the list of command line arguments to run

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs

InterruptedException - if an exception occurred during process exception

invokeProcess

public static int invokeProcess(List<String> commandLine)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Discards any output of the process.

Parameters:

commandLine - the list of command line arguments to run

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs

InterruptedException - if an exception occurred during process exception

invokeProcess

public static int invokeProcess(String[] commandLine,
 Reader input)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Additionally, allows one to supply an input stream to the invoked program. Discards any output of the process.

Parameters:

commandLine - the list of command line arguments to run

input - the input passed to the program

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs, or writing the process' inputs

InterruptedException - if an exception occurred during process exception

invokeProcess

public static int invokeProcess(List<String> commandLine,
 Reader input)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Additionally, allows one to supply an input stream to the invoked program. Discards any output of the process.

Parameters:

commandLine - the list of command line arguments to run

input - the input passed to the program

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs, or writing the process' inputs

InterruptedException - if an exception occurred during process exception

invokeProcess

public static int invokeProcess(String[] commandLine,
 Consumer<String> stdOutConsumer,
 Consumer<String> stdErrConsumer)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Outputs of the process (normal and error) are passed to the respective consumers.

Parameters:

commandLine - the list of command line arguments to run

stdOutConsumer - the consumer for the program's standard output

stdErrConsumer - the consumer for the program's error output

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs

InterruptedException - if an exception occurred during process exception

invokeProcess

public static int invokeProcess(List<String> commandLine,
 Consumer<String> stdOutConsumer,
 Consumer<String> stdErrConsumer)
                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Outputs of the process (normal and error) are passed to the respective consumers such that each line results in a separate call to Consumer.accept(Object).

Parameters:

commandLine - the list of command line arguments to run

stdOutConsumer - the consumer for the program's standard output

stdErrConsumer - the consumer for the program's error output

Returns:

the exit code of the process

Throws:

IOException - if an exception occurred while reading the process' outputs

InterruptedException - if an exception occurred during process exception

                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Additionally, allows one to supply an input stream to the invoked program. Outputs of the process (normal and error) are passed to the respective consumers such that each line results in a separate call to Consumer.accept(Object).

Parameters:

commandLine - the list of command line arguments to run

                         throws IOException,
InterruptedException

Runs the given set of command line arguments as a system process and returns the exit value of the spawned process. Additionally, allows one to supply an input stream to the invoked program. Outputs of the process (normal and error) are passed to the respective consumers such that each line results in a separate call to Consumer.accept(Object).

Parameters:
