描述

get_handle_objectget_handle_objectGetHandleObjectGetHandleObjectGetHandleObjectget_handle_object retrieves an iconic object associated with the KeyKeyKeyKeykeykey from HandleHandleHandleHandlehandlehandle and returns it in ObjectObjectObjectObjectobjectValobject. 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_generic_shape_model_paramget_generic_shape_model_paramGetGenericShapeModelParamGetGenericShapeModelParamGetGenericShapeModelParamget_generic_shape_model_param etc.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
