get_handle_tupleT_get_handle_tupleGetHandleTupleGetHandleTupleget_handle_tuple (Operator)
Name
get_handle_tupleT_get_handle_tupleGetHandleTupleGetHandleTupleget_handle_tuple — Retrieve a tuple associated with a key from a handle.
Signature
Herror T_get_handle_tuple(const Htuple Handle, const Htuple Key, Htuple* Tuple)
void GetHandleTuple(const HTuple& Handle, const HTuple& Key, HTuple* Tuple)
def get_handle_tuple(handle: HHandle, key: Union[str, int]) -> Sequence[Union[int, float, str]]
def get_handle_tuple_s(handle: HHandle, key: Union[str, int]) -> Union[int, float, str]
Description
get_handle_tupleget_handle_tupleGetHandleTupleGetHandleTupleGetHandleTupleget_handle_tuple retrieves a tuple associated with the KeyKeyKeyKeykeykey
from HandleHandleHandleHandlehandlehandle and returns it in TupleTupleTupleTupletupletuple.
The list of keys supported by a handle can be queried with
get_handle_paramget_handle_paramGetHandleParamGetHandleParamGetHandleParamget_handle_param.
Note that this operator is provided only for implementing generic
debug and inspection mechanisms.
The keys returned for certain handle types can change without notice.
Additionally, some handle types might not be supported by this operator.
Also, this operator is not optimized for performance.
To obtain more reliable information about a handle in a program, it is
strongly recommended to use the operators specialized for the particular
handle type, such as get_object_model_3d_paramsget_object_model_3d_paramsGetObjectModel3dParamsGetObjectModel3dParamsGetObjectModel3dParamsget_object_model_3d_params,
get_shape_model_paramsget_shape_model_paramsGetShapeModelParamsGetShapeModelParamsGetShapeModelParamsget_shape_model_params etc.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
HandleHandleHandleHandlehandlehandle (input_control) handle → HHandle, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of which to get the key.
KeyKeyKeyKeykeykey (input_control) string → HTupleUnion[str, int]HTupleHtuple (string / integer) (string / int / long) (HString / Hlong) (char* / Hlong)
Key to get.
Number of elements: Key == 1
Restriction: length(Key) > 0
TupleTupleTupleTupletupletuple (output_control) tuple(-array) → HTupleSequence[Union[int, float, str]]HTupleHtuple (string / integer / real) (string / int / long / double) (HString / Hlong / double) (char* / Hlong / double)
Control value of the key.
Result
If the parameters are valid, the operator get_handle_tupleget_handle_tupleGetHandleTupleGetHandleTupleGetHandleTupleget_handle_tuple
returns the value 2 (H_MSG_TRUE).
If the handle is invalid or does not support the given key, or if the
key references an iconic object instead of a tuple, an exception is raised.
