twisted.internet._signals._MultiSignalHandling

class documentation

class _MultiSignalHandling: (source)

View In Hierarchy

An implementation of SignalHandling which propagates protocol method calls to a number of other implementations.

This supports composition of multiple signal handling implementations into a single object so the reactor doesn't have to be concerned with how those implementations are factored.

Method install Undocumented
Method uninstall Undocumented
Instance Variable _installed If install has been called but uninstall has not. This is used to avoid double cleanup which otherwise results (at least during test suite runs) because twisted.internet.reactormixins doesn't keep track of whether a reactor has run or not but always invokes its cleanup logic.
Instance Variable _signalHandlings The other SignalHandling implementations to which to propagate calls.
