Method Detail

getOutputStream

public OutputStream getOutputStream()

Description copied from class: Process

Gets the output stream of the subprocess. Output to the stream is piped into the standard input stream of the process represented by this Process object.

Implementation note: It is a good idea for the output stream to be buffered.

Specified by:

getOutputStream in class Process

Returns:

the output stream connected to the normal input of the subprocess.

getInputStream

public InputStream getInputStream()

Description copied from class: Process

Gets the input stream of the subprocess. The stream obtains data piped from the standard output stream of the process represented by this Process object.

Implementation note: It is a good idea for the input stream to be buffered.

Specified by:

getInputStream in class Process

Returns:

the input stream connected to the normal output of the subprocess.

getErrorStream

public InputStream getErrorStream()

Description copied from class: Process

Gets the error stream of the subprocess. The stream obtains data piped from the error output stream of the process represented by this Process object.

Implementation note: It is a good idea for the input stream to be buffered.

Specified by:

getErrorStream in class Process

Returns:

the input stream connected to the error stream of the subprocess.

finalize

public void finalize()

Description copied from class: Object

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java^TM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Overrides:

finalize in class Object

exitValue

public int exitValue()

Description copied from class: Process

Returns the exit value for the subprocess.

Specified by:

exitValue in class Process

Returns:

the exit value of the subprocess represented by this Process object. by convention, the value 0 indicates normal termination.

waitFor

public int waitFor()

Description copied from class: Process

causes the current thread to wait, if necessary, until the process represented by this Process object has terminated. This method returns immediately if the subprocess has already terminated. If the subprocess has not yet terminated, the calling thread will be blocked until the subprocess exits.

Specified by:

waitFor in class Process

Returns:

the exit value of the process. By convention, 0 indicates normal termination.

destroy

public void destroy()

Description copied from class: Process

Kills the subprocess. The subprocess represented by this Process object is forcibly terminated.

Specified by:

destroy in class Process

create

private long create(String cmdstr,
                    String envstr,
                    String path,
                    FileDescriptor in_fd,
                    FileDescriptor out_fd,
                    FileDescriptor err_fd)

close

private void close()
