get_param_typesT_get_param_typesGetParamTypesGetParamTypesget_param_types (Operator)
Name
get_param_typesT_get_param_typesGetParamTypesGetParamTypesget_param_types — Get default data type for the control parameters of a HALCON-operator.
Signature
def get_param_types(operator_name: str) -> Tuple[Sequence[str], Sequence[str]]
Description
The operator get_param_typesget_param_typesGetParamTypesGetParamTypesGetParamTypesget_param_types returns the default data type
for each input and output control parameter.
The default type of a parameter is the type used in “simple mode” in
HALCON/C. This concerns parameters which allow more than one type
as for example write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string.
Hereby the types of input parameters are combined in the
variable InpCtrlParTypeInpCtrlParTypeInpCtrlParTypeInpCtrlParTypeinpCtrlParTypeinp_ctrl_par_type, whereas the types of output
parameters are combined in the variable OutpCtrlParTypeOutpCtrlParTypeOutpCtrlParTypeOutpCtrlParTypeoutpCtrlParTypeoutp_ctrl_par_type.
The following types are possible:
- 'integer'"integer""integer""integer""integer""integer":
an integer.
- 'integer tuple':
an integer or a tuple of integers.
- 'real'"real""real""real""real""real":
a floating point number.
- 'real tuple':
a floating point number or a tuple of floating point numbers.
- 'string'"string""string""string""string""string":
a string.
- 'string tuple':
a string or a tuple of strings.
- 'no_default'"no_default""no_default""no_default""no_default""no_default":
individual value of which the type cannot be determined.
- 'no_default tuple':
individual value or tuple of values of which the type
cannot be determined.
- 'default'"default""default""default""default""default":
individual value of unknown type, whereby the systems assumes it to
be an 'integer'.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Result
The operator get_param_typesget_param_typesGetParamTypesGetParamTypesGetParamTypesget_param_types returns the value 2 (H_MSG_TRUE) if the
parameters are correct and the helpfiles are availabe. Otherwise an
exception is raised.
