- Method Detail
  - finalize
```
protected void finalize()
                 throws java.lang.Throwable
```
    Finalize method.
    
    Overrides:
    
    finalize in class java.lang.Object
    
    Throws:
    
    java.lang.Throwable
  - getPID
```
public int getPID()
```
    Returns the PID of the process.
    
    Returns:
    
    The PID of the process.
  - getPGID
```
public int getPGID()
```
    Returns the PGID of the process.
    
    Returns:
    
    The PGID of the process.
  - getInputStream
```
public java.io.InputStream getInputStream()
                                   throws java.io.IOException
```
    Gets the input stream of the subprocess. The stream obtains data piped from the standard output stream of the process represented by this WrapperProcess object.
    This is an alias of the getStdOut() method.
    Implementation note: It is a good idea for the input stream to be buffered.
    
    Returns:
    
    The input stream connected to the normal output of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - getStdOut
```
public java.io.InputStream getStdOut()
                              throws java.io.IOException
```
    Gets the input stream of the subprocess. The stream obtains data piped from the standard output stream of the process represented by this WrapperProcess object.
    This is an alias of the getInputStream() method.
    Implementation note: It is a good idea for the input stream to be buffered.
    
    Returns:
    
    The input stream connected to the normal output of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - getErrorStream
```
public java.io.InputStream getErrorStream()
                                   throws java.io.IOException
```
    Gets the error stream of the subprocess. The stream obtains data piped from the error output stream of the process represented by this WrapperProcess object.
    This is an alias of the getStdErr() method.
    Implementation note: It is a good idea for the input stream to be buffered.
    
    Returns:
    
    The input stream connected to the error stream of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - getStdErr
```
public java.io.InputStream getStdErr()
                              throws java.io.IOException
```
    Gets the error stream of the subprocess. The stream obtains data piped from the error output stream of the process represented by this WrapperProcess object.
    This is an alias of the getErrorStream() method.
    Implementation note: It is a good idea for the input stream to be buffered.
    
    Returns:
    
    The input stream connected to the error stream of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - getOutputStream
```
public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException
```
    Gets the output stream of the subprocess. Output to the stream is piped into the standard input stream of the process represented by this WrapperProcess object.
    This is an alias of the getStdIn() method.
    Implementation note: It is a good idea for the output stream to be buffered.
    
    Returns:
    
    The output stream connected to the normal input of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - getStdIn
```
public java.io.OutputStream getStdIn()
                              throws java.io.IOException
```
    Gets the output stream of the subprocess. Output to the stream is piped into the standard input stream of the process represented by this WrapperProcess object.
    This is an alias of the getOutputStream() method.
    Implementation note: It is a good idea for the output stream to be buffered.
    
    Returns:
    
    The output stream connected to the normal input of the subprocess.
    
    Throws:
    
    java.io.IOException - If we are unable to access the stream.
  - waitFor
```
public int waitFor()
            throws java.lang.InterruptedException
```
    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.
    
    Returns:
    
    The exit value of the process. By convention, 0 indicates normal termination.
    
    Throws:
    
    java.lang.InterruptedException - If the current thread is interrupted by another thread while it is waiting, then the wait is ended and an InterruptedException is thrown.
  - exitValue
```
public int exitValue()
              throws java.lang.IllegalThreadStateException
```
    Returns the exit value for the subprocess.
    
    Returns:
    
    The exit value of the subprocess represented by this WrapperProcess object. By convention, the value 0 indicates normal termination.
    
    Throws:
    
    java.lang.IllegalThreadStateException - if the process is still alive and has not yet teminated.
  - isAlive
```
public boolean isAlive()
```
    Returns true if the process is still alive.
    
    Returns:
    
    True if the process is alive, false if it has terminated.
    
    Throws:
    
    WrapperLicenseError - If the function is called other than in the Professional Edition or from a Standalone JVM.
  - destroy
```
public void destroy()
```
    Kills the subprocess. The subprocess represented by this Process object is forcibly terminated if it is still running.
    
    Throws:
    
    WrapperLicenseError - If the function is called other than in the Professional Edition or from a Standalone JVM.
