120
|
|
|
|
|
|
|
|
121
|
|
|
|
|
|
|
This package provides core start/stop logic for all processes |
122
|
|
|
|
|
|
|
and devices. |

=head1 DESCRIPTION |
125
|
|
|
|
|
|
|
|
126
|
|
|
|
|
|
|
This package provides the core run/stop logic for EventStreamr. A |
127
|
|
|
|
|
|
|
process will extend this and provide any extra logic specific to its |
128
|
|
|
|
|
|
|
needs. |
129
|
|
|
|
|
|
|
|
130
|
|
|
|
|
|
|
It consumes the 'ProcessControl' role with requires a 'cmd' attribute |
131
|
|
|
|
|
|
|
and will utilise an optional 'cmd_regex' if one exists. |
