Detailed Description
Graceful shutdown adds signal handling support for gracefully terminating a WOApplication. The default implementation in ERXApplication simply calls the terminate method. By default only the TERM and INT signals are registered to handle.Member Function Documentation

- Returns:
- the default handler
| void handle | ( | Signal | signal | ) |
Signal handling method. Gracefully terminates the currently running WOApplication.
- Parameters:

| static void installHandler | ( | ) | [static] |
Installs signal handlers for the given array of signals. Default signals to catch are TERM and INT. The previous handler is saved to chain back to if anything goes wrong with the graceful termination method.
| static boolean isEnabled | ( | ) | [static] |
Determines if signal handling is enabled. Defaults to false.
- Returns:
- if signal handling is enabled
| void setDefaultHandler | ( | SignalHandler | value | ) |
