Constructor Detail

ForOpenJ9

protected ForOpenJ9(Socket socket)

Creates a new virtual machine connection for OpenJ9.

Parameters:

socket - The socket on which this VM and the target VM communicate.

Method Detail

attach

public static VirtualMachine attach(String processId)
                             throws IOException

Attaches to the supplied process id using the default JNA implementation.

Parameters:

processId - The process id.

Returns:

A suitable virtual machine implementation.

Throws:

IOException - If an IO exception occurs during establishing the connection.

attach

public static VirtualMachine attach(String processId,
                                    int timeout,
                                    VirtualMachine.ForOpenJ9.Dispatcher dispatcher)
                             throws IOException

Attaches to the supplied process id.

Parameters:

processId - The process id.

timeout - The timeout for establishing the socket connection.

dispatcher - The connector to use to communicate with the target VM.

Returns:

A suitable virtual machine implementation.

Throws:

IOException - If an IO exception occurs during establishing the connection.

loadAgent

public void loadAgent(String jarFile,
                      String argument)
               throws IOException
