CaptureStreamHandler

public CaptureStreamHandler()

Method Detail

run

public static String[] run(String[] cmdline)

Runs an executable and captures the output in a String array

Parameters:

cmdline - command line arguments

Returns:

output of process

getOutput

public String[] getOutput()

gatherOutput

public void gatherOutput()

Reads concurrently both the process standard output and standard error. The standard error - if not empty - is copied to the output string array field. Otherwise the standard output is copied to the output field. The output field is set to an empty array in case of any error.

setProcessErrorStream

public void setProcessErrorStream(InputStream is)
                           throws IOException

Install a handler for the error stream of the subprocess.

Specified by:

setProcessErrorStream in interface org.apache.tools.ant.taskdefs.ExecuteStreamHandler

Parameters:

is - input stream to read from the error stream from the subprocess

Throws:

IOException

setProcessInputStream

public void setProcessInputStream(OutputStream os)
                           throws IOException

Install a handler for the input stream of the subprocess.

Specified by:

setProcessInputStream in interface org.apache.tools.ant.taskdefs.ExecuteStreamHandler

Parameters:

os - output stream to write to the standard input stream of the subprocess

Throws:

IOException

setProcessOutputStream

public void setProcessOutputStream(InputStream is)
                            throws IOException

Install a handler for the output stream of the subprocess.

Specified by:

setProcessOutputStream in interface org.apache.tools.ant.taskdefs.ExecuteStreamHandler

Parameters:

is - input stream to read from the error stream from the subprocess

Throws:

IOException

start

public void start()
           throws IOException

Start handling of the streams.

Specified by:

start in interface org.apache.tools.ant.taskdefs.ExecuteStreamHandler

Throws:

IOException

stop

public void stop()

Stop handling of the streams - will not be restarted.

Specified by:

stop in interface org.apache.tools.ant.taskdefs.ExecuteStreamHandler
