                      throws AttachNotSupportedException,

java.io.IOException

Method Detail

detach

public void detach()
            throws java.io.IOException

Description copied from class: VirtualMachine

Detach from the virtual machine.

After detaching from the virtual machine, any further attempt to invoke operations on that virtual machine will cause an IOException to be thrown. If an operation (such as loadAgent for example) is in progress when this method is invoked then the behaviour is implementation dependent. In other words, it is implementation specific if the operation completes or throws IOException.

If already detached from the virtual machine then invoking this method has no effect.

Specified by:

detach in class VirtualMachine

Throws:

java.io.IOException - If an I/O error occurs
