Method Detail
-
getSpec
public Spec getSpec()
Description copied from interface:YamcsService
Returns the valid configuration options for this service.- Specified by:
getSpec
in interfaceYamcsService
- Returns:
- the argument specification, or null if the args should not be validated.
-
init
public void init(String yamcsInstance, YConfiguration config) throws InitException
Description copied from interface:YamcsService
Initialize this service. This is called before the service is started. All operations should finish fast.- Specified by:
init
in interfaceYamcsService
- Overrides:
init
in classAbstractYamcsService
- Parameters:
yamcsInstance
- The yamcs instance, or null if this is a global service.config
- The configured arguments for this service. IfYamcsService.getSpec()
is implemented then this contains the arguments after being validated (including any defaults).- Throws:
InitException
- When something goes wrong during the execution of this method.
