copy_dictT_copy_dictCopyDictCopyDictcopy_dict — 复制字典。
签名
描述
copy_dictcopy_dictCopyDictCopyDictCopyDictcopy_dict creates a deep copy (i.e., all contained handles and iconic
objects are deep copied) of the dictionary DictHandleDictHandleDictHandleDictHandledictHandledict_handle in
the dictionary CopiedDictHandleCopiedDictHandleCopiedDictHandleCopiedDictHandlecopiedDictHandlecopied_dict_handle。
If DictHandleDictHandleDictHandleDictHandledictHandledict_handle contains a handle that can not be copied or
that has been freed already, an exception is raised per default.
This behavior is controlled by GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name
'raise_error_if_content_not_serializable'"raise_error_if_content_not_serializable""raise_error_if_content_not_serializable""raise_error_if_content_not_serializable""raise_error_if_content_not_serializable""raise_error_if_content_not_serializable", and the corresponding
GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value can take the following values:
- 'true'"true""true""true""true""true"：
The default: Errors are raised and the copy process aborted.
- 'low_level'"low_level""low_level""low_level""low_level""low_level"：
Only low level errors are raised. Instead of the handle concerned an empty
handle is copied in CopiedDictHandleCopiedDictHandleCopiedDictHandleCopiedDictHandlecopiedDictHandlecopied_dict_handle and the copy
process will be continued. The behavior regarding HALCON low level errors
is determined by 'do_low_error'"do_low_error""do_low_error""do_low_error""do_low_error""do_low_error" in set_systemset_systemSetSystemSetSystemSetSystemset_system。
- 'false'"false""false""false""false""false"：
The errors are suppressed. Instead of the handle concerned an empty
handle is copied in CopiedDictHandleCopiedDictHandleCopiedDictHandleCopiedDictHandlecopiedDictHandlecopied_dict_handle and the copy process will be
continued.
执行信息
- 多线程类型：独立（即使使用独占算子也能并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
