java.lang.Objectde.unihalle.informatik.Alida.tools.ALDOpRunner
public class ALDOpRunner
Generic commandline interface to run an Alida operator. The operator needs to be annotated to allows execution mode CMDLINE.
Reading of IN and INOUT parameters and writing of OUT and INOUT parameters
is accomplished using the interface ALDDataIOCmdline
in conjunction
with ALDDataIOManagerCmdline
.
For each parameter which should be read or written according to its
annotated direction
, a name=value pair has to be given as argument.
If the flag --donotrun
or -n
is given, only the parameters of the operator
and there details will be printed but the operator is not invoked.
The flag noDefaultHistory
specifies that not for each input parameter
a history file should be read and associated with the parameter for all data types
(irrespective whether the corresponding provider does so).
Likewise this flags specifies if a history is to be written for all output parameters.
If the flag --verbose
or -v
the interface of the
operator will be printed to stdout (and potentially further information).
