Class Process

consumeProcessErrorStream

public Thread consumeProcessErrorStream(OutputStream err)

 

Gets the error stream from a process and reads it to keep the process from blocking due to a full buffer. The processed stream data is appended to the supplied OutputStream. A new Thread is started, so this method will return immediately.

Parameters:

err - an OutputStream to capture the process stderr.

Returns:

the Thread

Since:

1.5.2

consumeProcessErrorStream

public Thread consumeProcessErrorStream(Appendable error)

 

Gets the error stream from a process and reads it to keep the process from blocking due to a full buffer. The processed stream data is appended to the supplied Appendable. A new Thread is started, so this method will return immediately.

Parameters:

error - an Appendable to capture the process stderr.

Returns:

the Thread

Since:

1.7.5

consumeProcessOutput

public void consumeProcessOutput()

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The stream data is thrown away but blocking due to a full output buffer is avoided. Use this method if you don't care about the standard or error output and just want the process to run silently - use carefully however, because since the stream data is thrown away, it might be difficult to track down when something goes wrong. For this, two Threads are started, so this method will return immediately.

Since:

1.0

consumeProcessOutput

public void consumeProcessOutput(Appendable output, Appendable error)

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied Appendable. For this, two Threads are started, so this method will return immediately.

Parameters:

output - an Appendable to capture the process stdout.

error - an Appendable to capture the process stderr.

Since:

1.7.5

consumeProcessOutput

public void consumeProcessOutput(OutputStream output, OutputStream error)

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. For this, two Threads are started, so this method will return immediately.

Parameters:

output - an OutputStream to capture the process stdout.

error - an OutputStream to capture the process stderr.

Since:

1.5.2

consumeProcessOutputStream

public Thread consumeProcessOutputStream(Appendable output)

 

Gets the output stream from a process and reads it to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied Appendable. A new Thread is started, so this method will return immediately.

Parameters:

output - an Appendable to capture the process stdout.

Returns:

the Thread

Since:

1.7.5

consumeProcessOutputStream

public Thread consumeProcessOutputStream(OutputStream output)

 

Gets the output stream from a process and reads it to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. A new Thread is started, so this method will return immediately.

Parameters:

output - an OutputStream to capture the process stdout.

Returns:

the Thread

Since:

1.5.2

getErr

public InputStream getErr()

 

An alias method so that a process appears similar to System.out, System.in, System.err; you can use process.in, process.out, process.err in a similar fashion.

Returns:

the error InputStream for the process

Since:

1.0

getIn

public InputStream getIn()

 

An alias method so that a process appears similar to System.out, System.in, System.err; you can use process.in, process.out, process.err in a similar fashion.

Returns:

the InputStream for the process

Since:

1.0

getOut

public OutputStream getOut()

 

An alias method so that a process appears similar to System.out, System.in, System.err; you can use process.in, process.out, process.err in a similar fashion.

Returns:

the OutputStream for the process

Since:

1.0

getText

public String getText()

 

Read the text of the output stream of the Process.

Returns:

the text of the output

Since:

1.0

leftShift

public Writer leftShift(Object value)

 

Overloads the left shift operator (<<) to provide an append mechanism to pipe data to a Process.

Parameters:

value - a value to append.

Returns:

a Writer

Since:

1.0

leftShift

public OutputStream leftShift(byte[] value)

 

Overloads the left shift operator to provide an append mechanism to pipe into a Process

Parameters:

value - data to append.

Returns:

an OutputStream

Since:

1.0

or

public Process or(Process right)

 

Overrides the or operator to allow one Process to asynchronously pipe data to another Process.

Parameters:

right - a Process to pipe output to.

Returns:

the second Process to allow chaining

Since:

1.5.1

pipeTo

public Process pipeTo(Process right)

 

Allows one Process to asynchronously pipe data to another Process.

Parameters:

right - a Process to pipe output to.

Returns:

the second Process to allow chaining

Since:

1.5.2

waitForOrKill

public void waitForOrKill(long numberOfMillis)

 

Wait for the process to finish during a certain amount of time, otherwise stops the process.

Parameters:

numberOfMillis - the number of milliseconds to wait before stopping the process.

Since:

1.0

waitForProcessOutput

public void waitForProcessOutput()

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The stream data is thrown away but blocking due to a full output buffer is avoided. Use this method if you don't care about the standard or error output and just want the process to run silently - use carefully however, because since the stream data is thrown away, it might be difficult to track down when something goes wrong. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish as well. Finally, the output and error streams are closed.

Since:

1.6.5

waitForProcessOutput

public void waitForProcessOutput(Appendable output, Appendable error)

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied Appendable. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish as well. Finally, the output and error streams are closed.

Parameters:

output - an Appendable to capture the process stdout.

error - an Appendable to capture the process stderr.

Since:

1.7.5

waitForProcessOutput

public void waitForProcessOutput(OutputStream output, OutputStream error)

 

Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish as well. Finally, the output and error streams are closed.

Parameters:

output - an OutputStream to capture the process stdout.

error - an OutputStream to capture the process stderr.

Since:

1.6.5

withOutputStream

public void withOutputStream(Closure closure)

 

Creates a new buffered OutputStream as stdin for this process, passes it to the closure, and ensures the stream is flushed and closed after the closure returns. A new Thread is started, so this method will return immediately.

Parameters:

closure - a closure.

Since:

1.5.2

withWriter

public void withWriter(Closure closure)

 

Creates a new BufferedWriter as stdin for this process, passes it to the closure, and ensures the stream is flushed and closed after the closure returns. A new Thread is started, so this method will return immediately.

Parameters:

closure - a closure.
